Looks like natural leave colours to me, don’t worry too much just keep an eye on it. Leaves are prone to develop mutations

Yellow and crusty leaves
Hey dear community, Why is my plant not recovering? I even adjusted the ph of the watering and add cal mag. Every week it’s getting worse and I don’t see any improvement. I use the fertilizer from Bio bizz and light is far enough away from the plant. Temp and humidity are fine

Co2/Temps/Nutrients
I pushed the temps up and got the VDP on point w/co2. Now since the plant is drawing a lot more water up through the roots, I've noticed very slight nute burn on the newest leaf growths. Do you have to drop PPM's as temps rise? I thought it was the other way around?

Nutrient lockout, ph imbalance or nutrient burn?
Unfortunately I don't have a ph meter, so my best guess is one or more of these problems: nutrient lockout, ph imbalance or nutrient burn. The first 3 photos are from an Auto Northern Light and the last 2 are from an Auto Jack Herer.

Cal/mag problem or heat issue?
A few leaves have some problem spots popping up here in week 6 (see pics). No nutes, PH’d water. FFOF/HF/Perlite mix for medium under 20 hours of light. I’m guessing either got too hot from being in 90F heat for an hour or needs cal/mag? Any advice from any veterans out there?

It got a little hot yesterday I think plants hit around 81 at one point when I was gone. Not sure if this is some heat stress and light burn or if it’s a nutrient problem. This is this only plant and only leaf with any signs of this

I think underwatering combined with the light being close has caused my issue. However older leaves have also dried up and died (but staying green). The way the leaf looks with yellowing though, and because a couple of leaf stems are turning reddish, maybe it's K deficiency?
