I find i need to add calmag with my tap water...it is pretty clean with a pm of about 27, last time I measured...easy enough I have a small pipette of the proper size and I just add one to each watering...I’ve been using a super easy nute called MegaCrop...you just mix it with water, ph and feed...but, it’s not organic and I’m gonna go fully organic this time outside and then perhaps inside in the fall...
I kinda thought that the pics look kinda like bugs though since it was all spots...seems like a deficiency would be more uniform but hey, I’m a beginner at this too...hope ya finger it out...!
