Charlie sheen crack issues!! Cal/mag or nute burn?!

I've had ppl tell me both and I'm just curious as to what the great minds here at RIU can lend more help!!
this is CFL all the way thru. Grown in soil, it's either happy frog or kelloggs topper with dol lime, worm castings, and bone meal. I rarely add nutes but use Buddha bloom and Buddha grow when needed. The plant in question does this every time I flower the strain. It's a 10-11 wk flower plant. And week 5-6 the leaves slowly turn like this then die snd fall off. Any ideas guys??

Calcium and potassium, either straight deficiency or a pH issue is my guess. Happy Frog plus dolomite should be pH-safe so perhaps lockout or Ca/K def. Flowering plants are hogs for both ime. But with bone meal, you should be fine for both Ca and P. So maybe potassium is where I'd concentrate my investigation.

How much and what color temp of CFLs? cn

Around 250w of 2700 k with a few 6500k bulbs.

Thank you for your reply tho!! Ill look into the p and be more careful with my ph. (Been doing 5.9-6.4 so far)

Actually it would be K (potassium) but you'll get it figured out. Im in agreement with cannabineer, looks like a K deficiency

Okay so I figured ill use my bloom nutes (Buddha bloom .5-2-1.5) on the next watering at say half strength?? That way p and k are covered?? What do you guys think???

You want approx. 2:1 K to P at this point imo. Too much P and you're risking a different lockout presentation. Jmo. cn

Lol fml. So what options do I have?? I don't have much $ for more nutes and would like to stay organic. I can only think of banana peels and only cause I know they have k.

Edit: or is it p??
