Looks like a pH issue from over ferting....pH for sure though....

Your getting lockouts...classic look of.

Never been a fan of FF nutrients....

I suggest a switch to something easier - Botanicare KIND line is my FAV synthetic.....Stupid simple and infinitely adjustable to suit strain needs...Works in all styles of growing....
Plenty of better things to choose from..

You do understand that RH and temp you run at,,,,,increases uptake and transpiration. Thus you get a higher nutrient dose to your plant daily...

Nutrient charting is done at specific Temps and RH values. They use the Vapor Pressure Deficit when setting feeding charts for Nutrient products.

You said over fertilizer but I'm only using half strength could it be possible it's magnesium deficiency?...brown rusty spots appeared before the yellowish leaves did and if it is locked out is there anyway to reverse this or am I screwed?

Ok, first off.
Leech the media (What are you growing in?) with plain water and a bit of Ca/mg.... pH that to 6.7 From now on, pH all in-going to that pH (for bloom - 6.5 for Veg)

Let that dry to needing a watering and water with the same thing a cpl of times b4 restarting nutrient.

Secondly. It's still a pH issue no matter if it came from over feeding or build ups or not having your feeding at the proper pH before using!

I'm using 3 gallon cloth pots smart pots whatever they call them...I'm using FF ocean forest soil for the medium ..I don't have a PH meter I do have a soil pH/light/moisture meter than has been reading 7 the entire time I'm giving nutrients..I did water yesterday and now it's dry again already....

Those soil pH meters are worthless for indoor pots. They give you an idea outside in the garden but not so good for potted plants.

It does look like too many nutes and pH probably due to that. Those pots are not very big. It doesn't take long to change the balance in smaller amounts of soil in pots.

Plain water is your friend. Don't dump massive quantities through but enough for some runoff.

I'm just repeating what @Dr. Who already stated but it's the best advice.

You're just going to have to ride it out. There is no solution in a bottle to fix what's wrong. In fact the bottle is probably what caused these issues.

You'll still get some bud.

Looks like you have a couple other plants. This is a learning moment to not do the same thing again. In Ocean Forest you can go awhile without any need to feed. And then when you start it can be half strength.

You're growing auto's correct?

Good luck
