Young plants with possible deficiency
They're under t5ho , about 8 inches away.
Humidity kept at 40% mostly
temp is 77-81
Watered with ph'd water (6.5ish)
Any ideas?
Two plants one topped and 1 non topped one. The none topped one looks like this too but not nearly as bad.
Roughly the same time this started (maybe a day or two after the spots started appearing) I had started using foxfarm nutes, I started them on a 1/2 teaspoon per gallon. Needing some help, new growth is looking fine though but it still bothers me.

If that's soil they are in, I would stop Ph'ing the feed, you will probably find they will stop being deficient then.
Soil contains lime and will buffer Ph on its own, as per nature, if you are lowering the Ph, then soil will further buffer it and lock out nutrients to your plants.
If you are in coco then ideally you need to have the Ph around 5.8, for best nutrient uptake.
In this case it looks like it has locked out calcium and nitrogen, I would give them a foliar spray with water and cal/mag once a day until they pick up as well
