Fan leaves are browning at the tip/turning up and feel crispy. and seems to be moving up the plant. With the same browning at the tips.. Roots are slightly brown and im pretty sure its not nute stained. Temp=75 RH=50% Nutes=400 and i just changed the reservoir 3/25/16 when the problem was minimal. And just changed it yesterday 3/30/16 and added minimal nutes=275. <PLEASE PLEASE HELP ME SAVE MY BABY GIRL> I use FloraNova Grow, and Liquid Seaweed/Sm-90 as a foliage spray. Also my reservoir is 3.5gal and i put a total of 6ml of sm-90 in the changed res and just 1/2 tbs floranova grow.
