What's wrong with my plant?

1/2 tbsp per gal of water of water for Epsom salt. If that worked no need for ph or cutting nutes. Just do a normal feed. Soil drench just means water a lil heavier. Epsom is organic nutes for mag and sulfur.. I just suggested that if foliar wasn't enough.

Some new pictures of my problem. I guess they did not plant anything and fixes. splashing the leaves with a mixture of epsom salt is a big help: (Now I have a new fertilizer from GH ([FONT=Arial, Helvetica, sans-serif]BioThrive grow, Bio Essential ,BioThrive bloom[/FONT] and Ph down). I really do not know how to help my plants: (

Report after 3 days. Plants are a little better. I fertilized with Bio thrive (added Ca and Mg + bio-essential). I've used water (RO). The mixture of water and fertilizer - PH 6.0 and 490ppm. It has been the following problem which is seen pictures.







The only problem is I do not have an organic Ca and Mg :/ For foliar spray using Bio Essentials 1,5ml/L ( (B): 0,01%, (Mo): 0,003%, (Co): 0,001%; (Fe): 0,1%; : 0,1%; (Mn): 0,025%; (Zn): 0,01%;: 0,01%; (Cu) 0,01%.)

Again will answer I have a new problem within 45 days of flowering. Currently I use FloraNova fertilizer (18ml/10L) + bio boost (2ml/10) + mineral magic (4g/10l). I use tap water and RO water (I mix ratio, 3-1). I currently 980ppm (1.9EC) and Ph 6.3. I can not find where it was a problem, or it can be too much nutrients?
