Hi guys,
I'm growing 2 plants right now, both have been on the same feeding schedule. One of them developing some discoloration, while the other is looking pretty decent.

pot: 1/3-gallon (1l) airpot
medium: biobizz light mix with a little extra perlite
nutes: Advanced Nutrients Sensi CalMag Xtra + Biobizz Grow
last feedings:
04-19: RO Water + 150PPM CalMag + Grow 1ml/l + Tap Water(for PH)
04-22: RO Water + 250PPM CalMag + Grow 0.6ml/l + Tap Water(for PH)

Any idea? Increasing CalMag doesnt seem to help.
Thanks!
