Could this be Leaf Septoria?

Bearijuana · Feb 27, 2019

There are 4 plants in here; 2 white widow extreme and 2 Northern Berry. 3/4 are bangers but 1/4, a White Widow Extreme has these leaves. They arrived a couple weeks ago on the fan leaves below. I attributed it to potentially low nutrient solution before I transferred all the individual DWC's to the RDWC system.
But now they are back again in the newer growth and only on one plant.

Great thanks! Well not great but easy fix. Fuck they consume a lot of calcium! I mean I add up and above GH 3 part but I guess not enough.

LED lights?

Yeah LED's really seem to make a plant consume more cal/mag.

Well that would make sense. Between my cobs and RO water, I'm adding like 1.5x the recommended cal-mag at the peak of bloom. Anything less and they start purpling and showing deficiency symptoms.

If only cal-mag didn't contain nitrogen... *sigh*

Yup. I use the GH Cal-Mag. It sure adds ppm to a solution!

I use GH CaliMagic, Joint Monster.
