Yellowing leaves Week 4 Flower

[OakRidgeReefer]

I’ve had almost zero issues up til this point. I fed my girl Saturday morning. 3-2-2 of the fox farm trio (big bloom, grow big, tiger bloom), Molasses. Kelp. Same mix as always.
Checked on her Sunday morning and the leaves were already at this point?? Would a deficiency appear this quick or am I missing something? All help is welcome.

Adding in some more info.

Feed full strength nutes once a week. Then follow with water w/molasses and kelp.

That could potentially be a potassium deficiency. Are you soil or hydro? A pH lower than 5.5 may cause a lockout of potassium and other macro nutrients. Otherwise, I say give it a bit more K. Perhaps someone else can chime in.

Fox Farms soil. Planned on flushing tomorrow morning to maybe reverse any effects. Will start back feeding next week.

Whoa, let’s not go doing anything crazy! Flushing half way through flowering would rarely be helpful. Most of your leaves are fine, and the lower leaves seem
To be the developing issue. This seems to me to indicate A mobile nutrient. Of them, this appears a lot more (to me) like a pottasium deficiency. There are some dark colors in some of your growth, and those and the clawing may be a nitrogen overload..stay away from nitrogen during flowering.

Your plant is going through a lot of phosphorus and pottasium right now. If you have been using your nutrients at a steady rate since flowering begun, it’s possible you may just be under fertilizing. I make my own dirt and don’t use chemical nutrients. Maybe someone else can help???

just a thought, I wasn’t adding kelp and molasses until the last two weeks. I have been adding them during my regular waterings as well as during my full strength water. Could that be causing issues?
