What I used was a 50 litre bag from Australia, and it might of been prebuffed for all I know. So you think the yellowing and droopiness are coming from lack of humidity? I’ll add a humidifier tonight if that’s the case. I wasn’t sure if it would make the fabric pots stagnated. Thanks for your info. I shouldn’t start new ones then I guess. Do they look good for 2 weeks old?All I can say is get the humidity up to 60-70%. Learn from your mistakes, as I buy Root Royale 50 L. for 4 3 gal pots. Needs no cal/mag to start the seedlings after they "firm up" into the coco.
Also should the humidifier be turned on at same time as the light or in “off” hours with the intake and oscillating fans turned still running.All I can say is get the humidity up to 60-70%.

Yes humidifier on when light comes on .your humidity usually rises lights off.i use an inkbird humidity/dehumidifier and basically set it say 65% and it will turn on when it drops..if it drops lights off make sure you tape up the light coming from the humidifier..near all good brands of bagged coco/perlite are buffered... professors nutrients (pn) 70/30 has a low ec of 500 which is pretty good to start with..Also should the humidifier be turned on at same time as the light or in “off” hours with the intake and oscillating fans turned still running.
Run off EC/ppm is good indicator for what's happening in the root zone. You can convert your ppm to EC from picture I posted above. EC is the first one which is measured in millisievert (mS).Thank you all for your advice. The yellow streaked one is the one concerning me the most right now and I’m thinking of taking it out of the tent incase it has a virus. I’ve seen yellow patching or spots but never stripes or streaks. I thought it might be something with the coco for sure. They’re doing great otherwise, even with only the six hours of humidifier on they’ve perked up a bit.
How can I check EC of soil with ppm meter? I’ve been checking feeding solution before I feed and then the runoff after I feed. Always between 30-70 ppm more after feed. Should I add more CalMag then what the company suggests so I can bring ppm/EC up?
Are they good size for being 2 weeks old from time of germination or am I slacking lol
Thanks for the feedback, humidifier’s been in all day now but it’s one of those little ones you put in a kids room, it’ll do for now. Any advice on the yellow oneAnd get the humidifier! :D
Let it grow. Miscoloured leaves are quite usual at this stage when growing from seed.Thanks for the feedback, humidifier’s been in all day now but it’s one of those little ones you put in a kids room, it’ll do for now. Any advice on the yellow one
That’s the first time I hear that term but phew, I thought I was going to have cull it lol. You guys are great, thank youVariegated leaves and or stems can come from a virus but yours are fine. These guys are taking me to the Promised Land, true harvest! Just enjoy. Peace.
Thanks for the advice. I’m into my second week of flowering now and the nutrient line I’m using is supposedly super chelated so just when I switched to 12/12, my solution only has a ppm of 570. All of veg it was in the 300-350 range and my runoff would be slightly lower after feeding, Ever since I made the switch to 12/12 I thought I had a magnesium or calcium deficiency because of rust spots on older leaves of one of my plants so I upped the amount I feed them to 1500ml a day. They are in 3 gallon fabric pots and there was still barely any runoff. I gave them slightly more the last 2 days around 2000ml each day and there was finally runoff but it came back double at 1140 ppm. I flushed one of them with tap water (57ppm in my city) today until the runoff went from 1140 to 210ppm. Not sure if that’s what I’m supposed to do but I figured I’ll try it with one and see how she reacts.Here are my tips for coco:
Plastic pots. Wet is your friend. No more than 3 gallons per 2x2 area.
Automation. Use pumps and timers.
Surfactants. Soap and or yucca root. Flushes salts and keeps everything wet.
ppms: 600-700 range.
Ph: 5.5-6.5
If you use low ppms, add a surfactant, and at least once a week water until runoff you won't need to flush.
Thanks for the advice, I read aquamans post on watering coco a little too late lol. He is also giving me advice. I'm going to give coco another go even if this run doesn't turn out great. But just like another post I read on here said, automation may be the only solution since my hand watering has been too inconsistent. My plants are on pot risers btw. Now I'm trying to figure out what automatic watering system I could incorporate for the last 3/4 weeks of my cycle.You water coco every day with food to achieve 10-20 % run off. This run off is what helps keep the salts from building up. It acts as a mini flush every time you water. If you water not enough your going to get lots of issues due to rising salt concentration. Also never flush coco w straight water. Always at least 1/4 strength otherwise you can completely strip all the nutes in your pot which can lead to problems in itself. Cal/mag deficiency etc. Read aqua mans post on watering coco it’s full of juicy nuggets (pun intended)!
I’m just learning this stuff too as I am on my first coco grow. It’s a great medium and the op is right about the perlite.
If your in a saucer put your pots on a lift so they don’t sit in the runoff. Once you get into it since your coco is at near saturation point consistently you won’t need to add too much water/nutes to achieve some run-off.
you want your runoff to be no more than about 300 ppm more than your input. If it gets higher then add a watering cycle, lower your nute strength, or water more volume to get more runoff. Your plants will rebound and all your hard work will not be in vain.
Initially when you water 1/4 strength to get the ppm down from nuclear levels bring it down only to the poms your already watering with. 800ish is typical. Can be 600 and even easier to keep from getting out of hand and 600 is def enough for your plants to thrive. Just a learning curve
