really dont know what to do please who has experie...

Firstly, your pH is way too high. Try to get it down to around 6.3. Secondly its clearly too warm in there, and your light is too close -back it off, and get some air moving in there. You leaves will probably stay curled but as long as your new growth is find, youll be ok. Just went through this myself.

Hello couple of things one if your plant is stressed one thing you can do is raise the light as it pushes the plant to perform when it too close and if the plant has a problem then it can magnify issues. Two plants of this age should never need fertilizer even in the worst soil mixes so I would hold off on those for now. And lastly with organic nutrients ph is maybe more important as these nutrients are not as salt based but based more on the calcium they are bonded to and calcium is only brought up into the plant in a very specific ph range. So checking your ph and making sure your feeding within that range is very important

Hi there! Strange situation, since your light distance seems fine and you stopped nutrients intakes... Maybe you have some broad mites, they're almost impossible to see without a microscope. An affected plant will show twisted new growth, blistered and “wet” looking leaves. If so, I'd recommend to spray your babies at night with low doses of neem oil. If none of these symptoms look familiar to you, then your issue is related to heat stress and/or nutrients lockout. I'll be around, keep us up-to-date so we can help you adjust your parameters, see ya!

Hi so when I first read your diary, I noticed the strong lights, slightly high ph, and a relatively low humidity for this young. I think your issue lies with either heat/light stress, lack of moisture in the air and potentially root related issues. Taco leaves and crispness are characteristic of these problems. I recommend that if you don't already, increase air flow a fan or exhaust system especially with hid, up your moisture, water your plants off and on with nute and regular water, possibly add a calm supplement, and if at all possible get a ph pen. I hope your problems sort out best of luck. Oh ps. Perhaps take light down to an 18/6 schedule for more rest.
