I found a light leak, I got suspicious when after about 2weeks of 12/hr of light plants were still growing and not stretching, plus no little buds.
Leak has been fixed and after just 2 days plants start stretching showing signs of asymmetrical growth at the nodes, you can see in couple pictures I took.
The yellowing might not of have been a deficiency but rather just normal for new growth, which turned green after a day or two.
Couple leave show sign s of CalMg deficiency, added half strength Megacrop version of CalMg.
The girls look healthy and are getting bushy due to my LST training, will do some pruning at next feed.
