The plant is Third Demension from TGA. I started them (after seedlings rooted) it in a local soil that has a bit of blood/bone and others added(not much). When the fan leaves started yellowing from the bottom up i thought it could be too much N so i waited a week to see how it did and it was still yellowing so i went out and grabbed a General Organics GO box. Started at a low dose every watering of grow/CaMg+/Bio root/Bio Weed/Bio Marine and now feeding slightly over a heavy dose. Sometimes i cant grab RO water so i use tap water, its got a decent amount of Mg and Ca so maybe its to much Ca-Mg? but when i use tap water i only use half a Tsp of CaMg+. The yellowing/discoloring is now in the other leaves and branches of the bottom of the plant. The other three plants (not the same strain) with it are all doing fine and have a nice dark green lush coloring. I dont PH because the GO box said it balances itself but i plan on getting a tri-pen tomorrow. .18/6 lights (switches from side T5's and a 400w MH above)Water when its pretty dry.It doesnt look root bound (just checked) but itll be getting a new pot before flowering.yellowing starts from the edges and works in. Ignore the burnt tips i found them growing to close to the T5's Cant seem to add pictures.... RIU seems messed up right now, i guess ill try to put pictures up later.IMG_0107.jpgIMG_0103.jpg

I use the same nutes and not had that issue until flowering on some strains. Usually N.. the nutes take a bit to kick in.
