Leaves yellowing too fast in flower?

I have been feeding it this crap fox farm bloom nutrients and mammoth p i just feel the plant wants more those bites probably aren’t best. Feeding At ph of 5.8 is that too low? I just got blue planet nutrients I’m ditching the fox farm nutrients but hmm I wonder what this is
I'm gonna guess you have been using both of those bloom nutes since flip to 12/12? This usually happens when you feed heavy bloom feed too early. The conditions are top to bottom so it isnt hungry and its not N tox.

pH won’t matter as much in organics. That isn’t lockout from pH.
Did he say he was growing organically? Trying to figure out what his medium is. imho pH matters to an extent, I remember when using Earth Juice that shit would drop my pH to the low 3's and gave me all kinds of headaches.

FoxFarms is organic. Organics buffer themselves, so pH isn’t as huge as it is with synthetic chelated nutes, long as there’s no drastic swing. I have never had to pH with Roots Organics.

That def looks like some n tox to me, may be a secondary issue. Just because there is yellowing doesn't mean it can't have a N toxicity issue, it may have been as a result of trying to correct yellowing by adding extra N.

Also, excess K and P I wouldn't think would cause such yellowing just based off a simple antagonism chart.

Please don't misinterpret me here lol I'm drunk and high it's late so I realize I may sound salty, I saw that he's using fox farm as his nutrients, but if he's running coco with perlite or peat with perlite that's 100% soiless and he should be shooting for 5.8. OP hasn't provided what substrate he's using, so we're all just speculating about the pH.

And that’s all I’m using

yea man I’m just using that one bottled bite the whole way and it worked great on my last grow but it seems this plant is a little more finicky

Again, it doesn’t matter. The pH range only applies to the uptake of synthetic chelated nutes, due to the range they are absorbed. In organics, which soilless can be and is in this case, microbes in the soil eat organic matter and shit out what the plants can take up immediately, pretty much regardless of pH. As long as your medium isn’t like, below 5, 5.5 and not above 7-7.5, it doesn’t really matter.

Ocean Forest, to my knowledge, isn’t soilless. It’s a supersoil, and it’s already hot. He shouldn’t even really be feeding like he is, because it’s a supersoil.

I want to say I am also feeding mammoth p twice a week 1 ml per gallon and recharge half a teaspoon per gallon once a week

Fox Farm Ocean Forest was on the first one.

I was just gonna say bro that I like FFOF, and use it at 50% to the Soilless Advanced Sunshine #4 at 33% and Vermiculite at 17% with Mykos and Azomite. I'm trying for an Organicish mix that's simple. Botanicare Pure Blend Pro, 1 part formulas, use Calmag Plus Grow thru stretch, then AN Flawless Finish MagSulphur product towards the end. The only special thing is an occasional Tea.

Hey guys Ok so I’m using fox farm ocean forest for soil and here’s a picture of what I’m using for nutrients

Have you been feeding all bloom nutes & mammoth P since flip to 12/12?
Also, notice how purple the petioles are.
