Pot size and coco mixture. I see hydroton and perlite, any soil mixed in as well or straight coco?
Three of them are 3 gallon smart pot and have of them are 2.5 gallon hempys. I have perlite hydroton and coco no soil.take my comment with a grain of salt. since i a fairly new also.. but the first picture looks like a PH swing.
I dropped everything but the floranova, armor si, added AN big bud coco, drip clean, and therpinator. I add orca and hydroguard once a week with some black strap for the sugar,mag,cal and iron. I am not really using cal mag right now just kinda seems a bit much with how much is in the floranova and big bud coco.
