Hi all:

I am growing in fox farm ocean forest soil 50% / sunshine mix 50% with added coarse perlite in 5 gallon pots. Plants looked healthy during veg and into first couple weeks of flowering, now some of the oldest, biggest bottom fans leaves starting to dry and die....help please.

I am using the fox farm regimen at approximately 50% recommending dosage per their schedule, alternating with plain ro, ph'd water at approximately 6.5. I am running co2 at 1500 ppm in a almost sealed room. Temps range between 70-85 and rh runs between 50-70%. I am planning to run dehumidfier starting week 4 keeping at 50%. I let the

The plants started off so darn healthy, and now I am starting to wonder wtf I am doing wrong.

Any suggestions are greatly appreciated all!!

i wouldnt say nute burn but wrong formula, my stuff did the same with fox farm line. you can go with a 25%bloom 75%grow untill you get them back on track then maybey 50 50 grow bloom.

Im hoping to go all organic, but this round is leaving me scratching my head. I have used ff for quite a while, and usually went pretty darn well, but something has certainly changed - lost my greenthumb

it could be a nute lockup then. see plants take what they want and leave what they dont. maybey your water is harder than before or something. i used to get that problem with bloom nutes, over or under watering. but the lockout was mainly due to my hard water. i was useing it not knowing what was in it, found out its 980 ppm well water after loseing many plants to nute lockout.

yes i would blame that if its the only thing you changed in your recipe. the water at every location is very different

my suggestion is your probably going to have to look into getting a reverse osmosis filtration system for the ladies. untill then you may have to buy ro water at the local food mart.
