I believe its Boron deficiency, but not sure.

I haven't dealt with Boron deficiency, but from the guide I'm taking a shot this is what we're dealing with. Any suggestions would be helpful.

Looks like pest problems. Specifically fungus gnats. Not much info to go on but looks like some leaf curl as well might be overwatering.

Just changed to 6.0 last water from 5.5-6.0 (read that sativa like lower pH, but for soil its too much apparently). We use a 3-in-1 anti-fungal/pest/bacterial, but Neem Oil is on the list as well.

Soil ph soil should be between 6-7 no matter if it's sativa or indica. The leaf curl still makes me wonder if you're overwatering which can cause deficiency. It can clear itself up after fixing ph and not overwatering.

Okay excellent, thank you!
