Gelato#33 looks sad

That my friend is a case of multiple issues and some steps need healthy steps before even trying to apply and growing techniques, I'm thinking it's your mix. It's too compact, and that's why 1 problem is leading to many. I really don't think it's the case that you are doing a lot wrong, it's just 1 r 2 even crucial steps. Root teapmeant can lead to all them problems, PH BUILD UP/ NUTE LOCK OUT, Why you ask am I'm coming to this conclusion, well it's simple. Only parts of your plant are deformed, discoloured and so on, if it was a problem of too much nutes or ph problems it's effect all the roots, meaning your whole plant would show signs of sickness. Try this. It is very very risky, and could mean your plant will die. But in it's current state she will not make it to harvest. Carefully take her out substrate and roots intact, and go through her and see if you have root development through the whole plant and if so just pop her back in the pot. If not, just break and it'll be a mission but lay the plant on its side with pot pack in soil then lay roots on and more soil doing layers, oh but before being that you have her out go through and give a root bath for a few hours. 5.8 PH. That's very drastic, I know. But it's just hard to believe that all these problems are dwn to many problems 1 major problem can cause lots of problems also if it's too compact you'll have a lot of root rot due to lack of O2. Best of luck my friend.

I believe your humidifier should not be pointed directly on the plants. I'm guessing that's why looks limp. The browning looks like maybe needs magnesium.
