Sorry guys panciek
Sorry bro, I'm feeding when pots are light. Don't know ppm, ph 6.5 always, it's a mix of coco and Pete 40/60 if I remember correctly. It was all going dandy then all of a sudden rust spots. I got the feed charr off here woody his name is with his biobizz feed schedule. Starts off 1ml or so up to 4ml.
