Magnesium?

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.

calisun will become famous soon enough
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?

99% positive it's from nutrients being splashed on the leaves. This is very common and usually freaks people out. I would not start adding adding more
