That's plenty of humidity; my plants are in 35-40% humidity without that problem, of course I am also giving them silica.

But I want to know if you are feeding with micronutrients too, if you have a complete fert?

Zinc def/lockout can cause crinkly weird-looking new growth.
stinkyattic Reviewed by stinkyattic on . What is my major malfunction?? PICS ok guys these baby girls are about 2-2.5' tall and are placed into 5 gallon buckets. lots of holes so good drainage. this is day 5 of 12/12 and the top leaves and new growth seems spindly and weak. it is yellowing somewhat but I have heard that is normal for light shock in the first week of flowering. I use ph balanced water and nutes and check it every time. I haven't begun flowering nutes yet I was told to wait for a week of flowering and will be watering with big bloom in a couple days. can Rating: 5
