I was going to switch in spring but now I have another grow I'm using soil. It's actually the same mix @Jimster gave me for my mother plants. So far it's been incredibly easy. 2 weeks into flower and fed once at 400ppm. The plant are in perfect shape. Noticeably slower than hydro but none the less they look immaculate. Also under 1000w HPS. I have 2 complete opposite grows. Did a slurry test to start and adjust the soil ph to 6.4 I have someone watering and I pop in once a week or so. Not through a full grow yet but I don't foresee any issues.It can be a frustrating world in soil lol. I'm going the other way and moving to hydro to get more control. Hydro at least has more absolutes, soil can be a guessing game at the best of times.
I am seeing issues on the leaves on all my plants and I always ph my feed and water to around 6.5 - 6.6 I've fed 3 girls 3 times over 7 weeks 3/3/3mm = 3/5 tsp Micro/Grow/Bloom General Hydroponics 3 part system.my tap waters ph is a bit over 7, my clear runoff is 6.2 consistently, it creeps up to 6.5 max in flower, it depends on what is coming out of your tap, a mild solution of baking soda will raise your ph, a very mild solution of waterd down white vinegar will lower it, if you have hard water you can distill it, or buy water at the store, or go buy something that will raise or lower your ph, i mentioned baking soda and white vinegar beacuse its cheap and really does work, you just have to go real mild.
You can't really trust ph of RO water. It has no carbonate or bicarbonate to keep it stable. Literally moving it from your basement that may have CO2 levels of 1200 to the upstairs that may have 500 can slightly alter the ph.I am seeing issues on the leaves on all my plants and I always ph my feed and water to around 6.5 - 6.6 I've fed 3 girls 3 times over 7 weeks 3/3/3mm = 3/5 tsp Micro/Grow/Bloom General Hydroponics 3 part system.
I noticed a problem with new growth on my 3 month old Cherry Bomb plant I'm still vegging. I was advised to check my RO ph and I found it to be at 4.8 ( I'd checked it a week or so earlier and found it to be ast 5,8) on all my plants, to low from what I've learned, here. I lifted the ph of my input water hoping to bring up the ph of the soil / promix but I haven't had success in doing that I still have low soil RO after flushing numerous times. I figured I'd flush out the salts and start fresh.
I flood the fk out of the plant, then let it drain completely 100% run off then do it again . Water shouldn't hurt it as long as it drains I figure. I always have 10 - 20% + run off when I feed or water then wet vac it up. I'm heading out for dolomite if I can find some in something other than a 40lb bag.
I don't have a PPM meter( coming soon I guess) so I can't check that yet. If I didn't have issues with the leaves I wouldn't bothered with any of this but I'd like to have this fixed yesterday because I'd like to turn them asap.
Slow down a bit... Is your plant showing signs of nutrient deficiency or burning? Or is it growing ok?
I advise never checking soil ph runoff, you're far better off doing a slurry test. Soiless like coco or rockwool sure, but stuff that has nutrients mixed in it can be very misleading and can cause you to attempt to correct problems that arent actually a problem, and 9 times out of 10 you just make things worse. If the plants are consuming a lot of positively charged nutrients like calcium or potassium, the roots can exude negatively charged hydronium ions that lower ph runof also, doesnt always mean there is a problem.

I'm glad to hear that things are working out well for you. How much difference are you seeing between the Promix VS the Hydro method that you used before? I've never tried hydro and haven't messed with my nutrient levels in the Promix for decades. I'm wondering if more often feeding would benefit anything or not. The period between waterings usually keeps buildups to a minimum, but I've been wondering if it would be worthwhile increasing the nutrients... either more nutrients or possibly the same nutrients but more often... maybe every 9 or 10 days instead of what I've been using. I would test it myself, but I have things dialed in pretty well and don't have the gumption to start taking notes and comparing potions. It doesn't get much easier and foolproof, but everything can be improved. I have quite a surplus currently and I don't know if I'm going to do another round of growing or not. Most of my harvest is for personal use, but I can't go thru all that I have in a couple years, so I also give it to some close old friends... but even they can't smoke it all. I have some totally new strains that I'd love to try my hand at, but I gotta find out something to do with all of this extra buds that have accumulated over the grows. Maybe edibles could help in using up the surplus....I was going to switch in spring but now I have another grow I'm using soil. It's actually the same mix @Jimster gave me for my mother plants.

The growth difference is very noticeable between hydro and soil but so is the amount of work out in to make sure thing go right in hydro. I spend close to 20min a day just testing, topping off and misc things in hydro. I go once a week and have a dude watering in between in that soil mix. Plants look perfect I don't think I wanna feed anymore than I have.I'm glad to hear that things are working out well for you.

So I thought as well. BUT I just fed one plan5/5/5 mil = tsp/gal MGB. I checked the ph and it read 6.56 so I fed the plant the gallon in a 3 gal pot and that gives me a good 10 -15% runoff. I checked the ph of this RO and it read 4.65 wtf I grabbed another sample of RO and got the same 4.65 wtf? this can't be good.....right? Plant has some leaf discoloration on a couple of leaves but how the FK does my ph RO go to such low numbers? It's ProMix I've not added any acid to this sht and only 6.5 water/feed and that was only it's 4th and largest feeding of its 7 weeks of life.You can't really trust ph of RO water. It has no carbonate or bicarbonate to keep it stable. Literally moving it from your basement that may have CO2 levels of 1200 to the upstairs that may have 500 can slightly alter the ph.
It has no ability to hold a stable. Ph without carbonate or Bicarbonate added. This is not really of concern in soil. When you add the water to the soil the soil will adjust the ph of the water to the ph of the soil.
Adding something like calcium carbonate, dolomite lime even baking soda (sodium bicarbonate) will raise the ph of the nutrient solution but also when you feed will stay in the soil and help raise the soil ph.
I'm not going to make suggestions there are some very good soil growers here that will do that.
I just want to explain that the PH of RO water and checking it is absolutely meaningless. It has no ability to alter the ph of anything and anything added to it will change its ph towards what was added.
Have you done the slurry test yet?So I thought as well. BUT I just fed one plan5/5/5 mil = tsp/gal MGB.

Nutrients as you know generally are slightly acidic. As they build up in the soil they can cause ph to become lower. There is also cation exchange. It's not abnormal for runoff to have a lower ph. And runoff may not be a good indication of soil ph. It's kind of a snap shot. A slurry test is much betterSo I thought as well. BUT I just fed one plan5/5/5 mil = tsp/gal MGB.

are you checking the PH of the RO water or the RO mixed with nutrients or the RO mixed with nutrients and poured through the medium and caught as run off?So I thought as well.

you might be flushing to much mate,problem from washing all the nutrients ,even pro mix can build bioligy,when i used it i just watered and feed like reg soil,never check runoff at all,i do always go buy the ppm chart as i do with every grow,that how i control the salt buildup,i just didnt exchange the air and feed as much,coco hell it takes a lot to get it a hydro speed,the pro mix didnt give me much problems,i just feed it when the bucket lean was light,once a week i gave the plants feed,you keep that pro mix happy it does do a good job,sorta like right in the middle of soil and coco what my experience was with it,me i would fix the problem with something like herculean harvest& olympus up,just seen that on a post by jwm and really like the idea of it,get with him on how to use but ya,stop the flushing thats were a bunch of rif raf startsI am seeing issues on the leaves on all my plants and I always ph my feed and water to around 6.5 - 6.6 I've fed 3 girls 3 times over 7 weeks 3/3/3mm = 3/5 tsp Micro/Grow/Bloom General Hydroponics 3 part system.
