Find out what your ph is. Looks like your getting ph lock and some minor nutes aren't moving. Anytime you see weird shit happening, start with ph and go from there.
 
Looks like potassium deficiency. I had that when my ph was out due to a out of wack ph pen.

I have to disagree. Mabey for your special situation but not at all relevant for the OP. It's a calcium deficiency. Calcium is immobile and there for move very slowly. Foliar feed with calcium nitrate. Add powdered dolomite @ 1tbsp/gallon of soil. Top dress lime and water in with pH adjusted and stableized plain or feed water. Better yet, use AACT to water in the top dressing. Mabey add a 2" layer on top of compost/castings. Continue the foliar for 2-3 days untill the lime kicks in.
 
If one were to insist on using an organic approach, yes you can double up on it but not too often. Like 2 times max. Otherwise you cave an overabundance of ca/mg and that can be harmful in time. Carbonates have to be broken down first by microbes before the plant benefits. This is why I advised a dual approach to remediate and maintain. Only a way to fast cure is synthetic foliar. Good luck on the grow bro.
