what are you feeding them, how much and how often. looks like you're possible overwatering as well. i've never seen the white bumps tho, not even in the plant problem sticky's. I'll be interested to see what the big dogs might say about that.

The white bumps are roots wanting to come out. If it was buried deeper those would all be new roots...

didn't think of that. good call. If so then I'd transplant to larger pots, those babies may be root bound and will suffer greatly if you don't do it soon.

It's possible that could be the problem with the leaves. But not 100% sure. It could be a thousand reasons for that. There are people on here that can look and tell better than I could. So I will leave it up to them. Could ask brick top. He really knows his shit...

You might want to try a 6500K lighting if you are vegging 24/0. The plant needs that blue spectrum. Than the hps for flowering. Or even better use both spectrum's. Its what I use and it works awsome

You need to be more specific. What is your setup like and what is your rituals like? how often you water, do you have a co2? indoor or outdoor grow? you know the basics, also what are you feeding it and how often?

thanks for quick reply everyone!
plants are ww and hawaiian haze there is 18 of them i am using organic soil mix and canna bio vega at the moment i mix 15-20 ml of canna per 10 liters of water and i water them once every 2 days.i will start flowering in a few days and will be using canna bio flores and canna boost later on. ph level is around 7.5/8 and i dont have anything to lower it. 2 days ago i ordered some epsom salt, ph up/down solution, carbon filter and fan but didnt arrive yet. i have another 400 watt hps bulb and as soon as i get a reflector i will start using it along with the 600 for flowering. some of the plants are in smaller containers i will move them to bigger ones tomorrow.the room is very messy and it doesnt have proper reflective material on the walls. i whill update pictures soon!

ph is high. might be causing nute lockup. i'd still flush repot them. those look like small containers. good luck!
