Heres the pics, all my specs are good, pH of ~6.45, 300watt hps, ~70F, etc... They are 3 1/2 weeks old, and I have no fed any nutes so I am positive its a deficiency and not a nute or pH burn because I use R/O water and have a digital pH/ppm meter. I also have they nutes to use: (botanicare) Cal-Mag, Pro Grow, Pro Bloom, Silica Blast, Liquid Karma. Have GH pH up and down. Need any more info please ask. Thanks for helping!! and the pics...
feed her then...if you know it is a deficiency b/c you have not fed her and she is 3 weeks old then feed her at 0.6-0.9EC and she should be fine.
