What is wrong with my bitches?

What's wrong with these? I have a feeling it's an obvious/classic something if you know. They have white or yellow at the edges of the leaves in the center of the pictures. Does it change the diagnosis whether they are white or yellow? Sorry bad photos.

More background: Different strains have same pattern. Before transplant they were somewhat malnutritioned in water only, were sexed, impregnated (not purposefully) and revegged. After transplanting into SIPs they greened up pretty fast but still getting used to it. Some fungus gnats about. Medium is organic modified coots with pete, 1/2 is new and other 1/2 is reused and ammended. Water is degassed tap 7.0 water only. Light HID mostly MH and a little HPS. Env tends to be 80F high 71 low and rH ~50% and rising. Is it just Ca? I think there's available Ca in the mix, but also there could have been dry pockets in the SIP. I guess I'd doubt heat stress because these leaves are lower down. I also guess there could be root issues that will likely prob1.jpgprob2.jpgrebound.

Did you add both oyster flour and gypsum to your mix, also, how much per cu ft?

I add gypsum at I think at ~ 4 Tablespoon per cu ft? I add Plant Tone at about 2 cu per cu ft I guesstimate, which has Ca too. I omit oyster flour and crab shell.

tough to find those charts when you want them.

I'm still thinking Ca def but accordingly that could also be from excess N, K, Mg, Na, or NH4+.
Does which is mobile/immobile in any way narrow it down further? Without that if I had to guess which most likely to be excess if any I say N or Mg. Mg because I top watered some. But usually I see Mg def.

Did you add any other nutrients beside traditional coots ingredients. Like blood meal or something.

Hi greenmachine, no bloodmeal. It's base is pete/perlite/compost. I'm more likely to omit but I put tiny bits of barley, neem, a little mgso4..nothing coots is against i think. I may mismeasure by accident like how much gypsum I guess but nothing obvious here I think.

Potassium deficiency? I had some Dracarys plants that were K whores, looked similar to this in the beginning.

Hi GrassBurner. Do you golf? I've hit a few of those in my time ;).

I was thinking potassium too but not as much so. Maybe you're right.

Yesterday I decided I'd try to top water a weak ACT so I started some. My thought was maybe the mychos could use some sugar. Of course I couldn't leave it alone so I put more in. I got very small amount of bag ewc, 1T molasses, 2tsp gypsum, dried marigold, 2tsp alfalfa. Today they get a cup or so. I don't recall if alfalfa is high K or high P. But we'll see. If they don't get worse I won't know if it helped but it wont have hurt.
