Leaves yellowing too fast in flower?

I ask, because Ocean Forest is already a pretty hot soil. Like, it’s already fully loaded with nutrition. That, plus all those nutes twice a week are probably locking you out. I only feed once weekly and water once roughly halfway between.

It’s been about 48 days since she was transplanted from a 16oz solo cup
Like, maybe now or as early as 10 days ago would have been a better time to start feeding. I think you overdid it with P and K. And organics don’t flush as well. It’ll be alright, I think, but stop feeding it so much. Give it just water for a bit. And maybe CalMag.

It could have also potentially run out of N, but that’s just an aside. I still think it might be lockout.

Yea but only since 12/12 in bloom in veg I get the grow big also fox farms line
Ok, this is what I was trying to get to. If you feed bloom nutes too early, they go yellow just like yours. They still require more N during the first 1-2 weeks from flip to 12/12 (stretch). If you keep a veg feed for the first week or two into transition to flower (during stretch) then at about week 3 start using the bloom feed I think you will have more success keeping them green until closer to harvest time. Then use the mammoth p around week 5 of flower once buds are well developed for the icing on the cake.

You think using a cal mag supplement that provided N to counteract the Bloom from transition? They need N to get through the stretch right?
Correct, The cal/mg will supply a small amount of N but not enough to work off of with using only a bloom nute and p-k boosters right from flip. Him being an 8 wk strain it wont be too bad. If it were a 10+ wk sativa he'd be in trouble right now.

Oh, I agree, I'm just thinking I could start my Bloom nutes at flip with CalMag, but yeah, def hold off on the pk booster till after the stretch.

So I just purchased some cal mag on amazon and I will feed straight ro but how many times a week water with cal mag?

Ok I understand yea man I fed really early like a week after flip. Thanks man that’s some good info I’m going to try it that way. Should I switch to better nutes for my next run?

pH won’t matter as much in organics. That isn’t lockout from pH.
hes been adding water at 5.8 to his soil mine always drops down a couple points from 6.8 to around 6.5 if I’m performing well. I’ve heard a lot about this with organic it doesn’t matter so how does this work out I’m interested ?

FF nutes are ok. They work. I'd suggest just dialing in what you are more familiar with now instead of changing stuff out. If you cant seem to dial it in after a couple tries with that nute, then switch it up to another. Just my .02

Sorry I didn’t explain that right, I put my water in at 6.8, 6.9 and when I test my run off it’s around 6.5

Because pH range is relevant to chelates because it can only take up certain nutrients in certain pH ranges. Because they’re nutrients bound to salts. With organics, you feed the soil microbes organic matter. Soil microbes eat matter and break it down into a form the plant can take up. When it comes to organics, pH only matters when it’s swinging way out of bounds, to the point of root rot or something.
