Hi there! Im DrDankness. I have about 3 years of growing experience. Ive always used soil to grow and this time i switched to Roots Organic soiless mix. Im currently a week and a half into veg. Im running 2x 600s over 15 Vanilla Kush. Im using 5 gallon buckets (im switching to 2 gallon pots with drain to waste drip system next time) Im doing LST for the first time. I attached pics of the nutes im using. Im giving 1/3 the CalMG and Grow and full strength root enhancer. I mix my nutes per gallon and hand water every 2 days for now. About 1/3 of my plants are having this issue. Leaves are turning and getting light colored spots that are dry and crumbly. Any help would be great!

No, but my watering can be a little haphazardly done. But theres a few leaves near the top that are twisting. At the moment ive switched to straight water.
 
Temps are around high 70s with lights on. My fans are tad bit small, but i just did a grow in soil with the same strain and didnt have these probs. There are no bugs that ive seen.
 
I hope its just something as simple as light burn from some water.Off PH can do this too, but doesnt make sense just 5 are doing this...Im sure you water and treat them all the same;)
 
Yes i sure do treat them all the same. Im hoping straight water will clear it up soon. I mainly just want the roots to beef up a lot before i flower them. I didnt think the nutes ive been using would burn since 2/3 of them are "organic" and ive been under dosing with grow formula.
