Leaves turing brown on tips and transparent

I'd imagine 0.5ml/l grow but check. Depends on your background EC.

Sorry what's an EC I'm not used to online shorthand o only made this account to ask about this grow in particular apologies for sounding like a noob. I filter my water in a Brita if that makes a difference thanks for the tip will do.

I grew some cheesecake autos with the same set up and I'm smoking that now and it turned put great that's why I can't understand the problem .

Ahh ok if filtered EC is low. Try 0.5ml/l no more. Ionic feed schedule is very high. Get an ec pen as well, you can see your exact nutrient strength then :) also try reading some Coco diary's here, search for bulls the user and basically copy if you want to be good right, bed. Back tomorrow.

Id also drop your PH to 5.8. Plants under LED will often need more cal mag. As nook says drop for now, they are young and you have put plenty through already. If you dont have some Epsom salts handy grab some, it helps plants uptake cal mag when you do feed it with some when applied with a foliar spray.

What's your "daytime" temp? What's your tent humidity? Gotta ask as well you did soak the coco and test the water ph before and after, does the coco have nutes added beforehand some do.
