How do I boost PK in soil I think I'm dealing with some kind of a deficiency or something

Hey thanks guys for taking a look at my plants if you can see there is some kind of a discoloration I've been strictly trying to stay organic in this fox farm ocean Forest I'm in 3 gallon fabric pots I've been using nothing but mykos and the soil it's self I started feeding with the only organic of the trio Big Bloom did a little couple tees over the past couple weeks with that I'm officially switch to flowering phase also so I'm thinking that the yellowing might just be the beginning of the stretch but what would you guys recommend I boost PK with in this soil

I like Earth Juice for bottled organic nutes. If you only want P and K Earth Juice Bloom would do it. I also like Neptune's Harvest Fish and Seaweed, but it has N too. There are dry organic amendments you can get too that could make things easier. Fox Farms even has some decent ones.

Your plants look ok to me. Maybe the newer growth is starting to get pale; pot up to a bigger size container if possible. Throwing a handful of chicken manure in the bottom of the next size container at the next transplant would help green them up. The idea is to give your plants all of what they need in the soil before you put in the plants. Then you just water as needed. Doesn’t get simpler. Thing is until you recycle your mix a few times you may need to provide a bit more npk and compost to keep the mix active through to harvest time.
If you are keeping the plants in the same container for longer than you should there are other ways to deliver npk to the root system without dumping synthetic nutes on them. Check out Jobes AP organic spikes. I push two into each final bloom container but you can stick them in anytime you need to feed plants for 8 weeks. You can stagger them by adding more spikes to feed longer but they are slow release. Takes a week or two for the spike to become available through decomposition. The other thing I suggest trying out is fish emulsion. I like Neptune’s Harvest with seaweed but any brand liquid fish like say maxi crop will work.
