Im guessing that when mixing in the added peat additional lime was needed to buffer the ph back up into the 6’s. The organic potting soil was likely buffered but the amount of lime it had is dilluted now.

Im sorry i dont know how to advise how much line to mix in as top dress but can be done. Go easy is always good advice.

Also maybe using tap water would be better than ro for the calcium content to help keep the ph up in the soil.

The seedlings look like their soil is acidic for sure.
Really? Tsp? I never heard that, but I'm willing to try anything and I seem to have multiple problems.

The blocks are nice and cheap. Mix with perlite and go. They will have nothing in them tho so at this stage you will need some calmag. I would definitely transplant tho. That soil is probably sure hot.
Ro water is fine in Coco. Will need to pH up tho at the end of mixing nutes (later when the plant is a bit bigger. No nutes other than calmag at this stage). With soil ph is supposed to be around 6.5-7 I think but with coco 5.7-6.0 is perfect. Once you get the coco mixed up, mix a batch of to water with calmag at 1/4 recommended strength and just keep pouring it through the coco mix to wash out anything in it. Transplant only after you've washed the coco a lot. When you water, go until you get a bit of runoff. If you wanna know when to water, the top of the coco can dry out and the pot can lighten up a bit and it's time to water again. You can overwater Coco but it is tough.
As far as your light goes, stretching is far prefered to drooping. Your light had a recommended hang height at the veg stage. Mine is 24" but 36" worked just fine for me. Too close and you're introducing heat and more light than they can process.
Hope you can pull this grow off. Hate to see a fellow medical patient suffering. Good luck!

Yeah I use tap water aka sink water lol I fill up what ever amount I need and let it sit out for 24 hours to dechorlinate you will see little bubbles form on sides of gallon jug after the 24hrs smack the jug and get all those bubbles out then it's good water then I go from there

This is my first grow and I am messing it up pretty good. I've made almost every mistake you can think of so far. Read on man. It's bad.

My seeds germinated fine. I transplanted them into a soil that I mixed myself with organic potting soil from home depot, pearlite, and peat. First I didn't have the lights low enough and they stretched. Moved to a few inches away from the 900w LED. Made the classic rookie mistake of overwatering. Got fungus gnats. Got rid of them using food grade Diatomaceous earth. Repotted them deeper to encourage more root growth and let medium dry out a bit. Temp is 77 with the use of a heater and RH is 60%. Running a box fan on low and a programmable humidifier. They are in a grow room that I created, which has no exhaust/ ventilation until this weekend. I'm trying to PH my water to 5.5, but it ends up at about 5.7.

My questions are: The bottom leaves are yellowing and I have very slow growth. What caused it and can I fix it? Seeds are expensive and I can't afford this chit. If it's the soil (I don't have a soil PH tester), can I change it out or is it too late for that? I'm not going to stress them out more than I have and I need to save them. I'm truly medical and can't afford to buy at the dispensary any more.
The pic I'm attaching is from a plant germ'd on 1/15, planted on 1/17. Today is 1/29. This is the only plant that is yellowing, but they all have stunted growth. Please tell me they are salvageable.
Welcome! Your pH is too low, you want 6.5 in soil, good luck!

So I need a PH soil tester, correct? I can't think of any other way to test it. And thank you. It's confusing. The soil has to be a certain ph and so does the water after the nutes are added, if you're using them in there first place. I've been growing stuff forever. I can't believe it's this complex. I really didn't think it would be.

I would bump that ph up to 6.5. Cause if you look at that chart I posted that is the ph range u want for soil and with a low ph range the roots cant uptake what they need as far as nutrition
But the only way to know the ph of the soil is with a soil ph meter, right?

Well u need a ph pen for your water and ppm meter aswell and u could get a ph soil tester but idk how accurate those are and personally I've never used one lol and I also look at each grow as science class cause each plant is different.

I can't wrap my head around that 🤣 How do I rinse the soil inside? I get why. I just don't get how. I originally had the light higher, but that's what stretched them. Then I read something else that said that they need the light as close as possible if it wasn't heat- producing and add long as it wad an 18/6 cycle, they should get as close add possible to the light. Everybody I watch day different things. It's frustrating. I've learned SOOO much in the last couple of months but everybody seems to have their nuances as to what they prefer. So every time I watch a grow video something is different.

I hear ya. I see that. Ppm meter... back to Google. Thank you very much. I really appreciate you guys helping me out. I can't afford the money or time invested in these things to lose them. Plus it's really irritating to lose them after all that.

I get how to PH the water and add nutrients. I don't get how you know the ph of your soil and how the 2 mesh together. I feel like I'm missing something really simple here.

There's a lot of info out there. I'll try to address as much as I can but people's opinions differ.
Stretching is okay. If you are confined with space you can low stress train them (plenty of LST how-to vids on YouTube) to keep the height down.
When you water your plants in Coco you mix your nutes, get your pH right and then water one plant until it's draining out the bottom into your drainage pan. I aim for about 20-30% of the water I put in to come back out. A good sized drainage pan helps to avoid spills. Then collect the drainage in a cup and pH and ppm test it. If you keep doing that every feed you will know intimately if things are good or going south. Aim for your runoff to be around 200ppm higher than your feed mix. My feed mix is usually around 6-800 ppm so I like to make sure my runoff is under 1000.

I use aquarium drops. Look up slurry test if you want to know how to check the pH of your soil I would start by adjusting the pH of what I'm pouring in 1st tho.

When I get a moment I'll read your thread and try to make rrecommendationls, it will probably be first thing in the morning

To test your soil search 'slurry test' and follow the directions; you will need some type of a meter or pH tester and a PPM pen to read the results properly though

If you find your soil PH low Dolomite lime is a great fix, normally used at one level tablespoon per gallon, I would recommend watering in just one level tablespoon/gallon initially and then re-testing the results because if you put too much it becomes very difficult to lower the soil pH

I would aim to balance your water out between 6.5 - 6.8. One of the good folks above shot over a chart showing where lockout can occur. Check your soil Ph as well. My sweet spot has been 6.8 ph in my soil and water.

Given you're hovering in the 5.something ph range I would guess lockout is the root cause.

Adjusting Ph in soil can be a major b*tch. Soil holds onto minerals and salts. If possible, I woule revert to the absolute basics. Repot into a fresh soil without any additives, let them recover and move forward.

I find a healthy soil as the base gets me through the first 3 weeks of growth without tinkering with it too much.

Best of luck to you. Looking forward to seeing your progress.

I saw that chart. I hope I thanked him for it. I thought that 7.2 was the correct zone for nutrients to be absorbed, but I always see conflicting information too. I'm afraid to change out the soil though. I'm going to expose the roots? And not kill it?

I reccomend going no higher than 6.8. Try to gravitate towards the middle of your nutrient uptake chart as possible.

Wear nitrile gloves while transfering your plant into a new container. Do your best to guess / feel if you're cutting into your root ball and slowly dig around the perimeter of your plant. When she lifts freely, give her a light shake. Expose those roots and lose some of the soil you're trying to leave behind. Tuck her into your new container and water immediately. Do NOT touch your roots with exposed skin.

Exposed roots arent a problem. Aeroponics relies heavily on roots to be exposed to oxygen. Large "grown up plants" have roots which can breach the top layer of soil. If you've ever walked through the woods and seen roots of evergreen trees and such exposed out of the ground - that was the tree working to pull in the oxygen it needed at one point or another.

Dont be afraid to make a mistake - plants in general WANT to live. If there is a chance at survival (no matter what you or I do) that plant will fight to thrive. Its nature ✌

Man, you are awesome. Really. That wasn't just a thorough explanation, but I feel like I could actually do it and not eff it up. I already have nitrile gloves. I use them for when I handle concentrates. I remembered what number you said for the ph. I just don't get how so many people vary in how they grow, but yet everybody seems to do ok. I've watched so many grow videos and there's not a lot* odd similarities. Except people seem to really like ffog. I wanted to try to do this as simply as possible and I ended up stressing the poor things out. Thanks for all the info and thorough explanations. I'm getting the coco on Friday. It's Amazon, so i assume I'll have it the next day. I'm not far from a warehouse.
