Week 3 of Flower, Largest Fan Leaves Near bottom Looking Burnt, Dead, etc.

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!!

these days i get my nutes made direct from a companny called hy -gen was on house and garden for years but i like this stuff now and i grow in coco not soil

cool thanks. so does it look like nute burn? deficiency? heat stress? Im gonna figure this one out. I shut the co2 off for now

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.

and are you useing ro water with calcium and mag supplements

and dont use the fox farm ec levels they will fry these plants. not your tomatoes tho they love a hot mix.

nope. was using rainwater last cycle but same shit happened to leaves so I switched to ro hoping it would help

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

I'll look into adding those to the water as well.

Props dude

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.

iv used hesi, fox farms, advanced nutes, you name it. now useing dyna-gro stuff is cheapest yet easiest iv used period.

maybe it is the water....we just moved to a new location

i use there veg formula for veg and a 50 50 veg bloom at first sign of blooming. but i hear their foliage pro is good from start to Finnish.

ill check that stuff out

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.

i hear ya. interesting tho that in veg and early bloom they look so healthy until about week 2-3

weird. thanks for your expertise tho! definitely gave me a lot of things to dial in!
