had some new growth come in slightly deformed almost like it got bit by something but no pest in sight , one or two leaves small yellow hole and one or two fan leaves had slight yellow tips other than that plants doing great!
Light is 19 in from tallest sight
RT-72-75
RH-58-60%
Coco perlite
Lotus nutrients- grow 1.75 tsp per gallon
Lotus nutrient-cal mag 0.5 tsp
6.5ph
Should mention feed twice a week once with grow and the other just water with a smaller dose of cal mag any suggestions?

Leaves look eaten. Got a cat? Coco, should aim for 5.8pH, or at least maintain pH around 5.5-6.1., what's ur ppm/ec?, what's ur ppfd?

Yes now that you mention it it says it’s pre buffered with calcium

Thanks for that. Both Mg and K can be an issue with coir also. Looks like the coir could be depleting Mg availability. You might want to supplement with some Mg sulfate. Maybe @Captspaulding could offer some input. He knows his coco.

I will definitely be trying the spray at lights off and in soil method , I’ve been using cal mag but feel like the pre buffered coco is retaining most of it and just passing my calcium
