Plant problems

My thinking is the FFOF intial fert charge ran out. Your using RO water every other watering with low fert levels on Sunday. There are micros in the TB but you are at such low levels and with the Cal Mag you can push up soil ph which limit micro uptake. You might have a micronutrient deficiency going on.

What is the ec of your regular Sunday fertilizing?

Teaspoons right? That’s really weak.
If my math is correct a 1/4 tsp(teaspoon) is 8-32-16 PPM N-P-K in the Tiger bloom plus the other stuff. If that is the case, how long have you been at this level?

Since I started
