Hi guys!
I´m running this Blackshead auto and the day before yesterday some leaves started to get yellow. Is this a Mg deficiency?
Soil: peat + perlite, some composting liquid @ 3-1-1 NPK and a few days ago some peruvian bat guano. PH at 7.0.
Thanks,
Thanks. I checked it out and seems to be OK these lower/early leaves get yellow and drop. Anyways, I add some Epson salts. I´ve been trying to lower PH but to no avail. Watering with 6.3 water PH by adding lemon drops. BTW, organic.
I'd think it was low P due to them being in flowering and needing more P and the purple petiole and necrosis. You haven't fed them anything other than what you listed?
