What's my plant missing? Growth has slowed down, and I think I'm seeing veinal chlorosis, see last picture in week 2 / or attached pic.
I've been feeding A + B with a tiny bit of cal+mag at an EC of 0.8, now reduced to 0.6, pH around 6.
Pure and simple - "Gimme some grub, bro!" :)
Add nutrients to increase the nitrogen. CalMag or the Micro nutrients. It should clear up in a few days to a week tops. Keep an eye on the ppm and pH! I always shoot for 5.95 pH.
