Ive looked around and haven’t been able to figure this problem out to one of my plants this week so im looking for help lol. My strongest looking plant till now started getting some brown/dead spots on the leafs which i was thinking may be a Manganese problem, but then the leaves started yellowing and canoeing pretty fast and its all around about the mid level of the plants. I got some CalMag to put in my RO water since i though it was gonna need it anyways, but it dropped my PH to 5.8 and i though that was on the lower side so im waiting on PH up to get here. Am i looking in the right direction to solve my problems or way off haha. Ive also checked a small section of roots due to still learning how to water them with out over/underwatering.
