Hello everyone. Just got my new basement grow up and running and I already have an issue down there. Probably about 20% or so of my plants have these rust colored spots on them and some even have it around the edge of the leaves. I'm thinking it's a calcium deficiency but not quite sure.
Im in 2 gallon root pouches and just started week 2 of flower
Medium is Canna coco with about 20% perlite
Greenstone coco base nutrients at 4 - 4.5ml per gallon
I'm using local tap water which is about 45ppm
I dropped the Calimagic down to 3 - 3.5ml per gallon since I figured there would be some in the tap water
I flushed them and upped the calmag to 4ml per gallon the last two feedings
Lights are 6kw total, 4kw DE HPS, 2kw SE HPS
I'm wondering if I'm underfeeding a bit after going from 2kw to 6kw?
Any help or advice is appreciated , thanks
