All of my plants have started to burn yellow in colour when they switched to flower, they have also lost they lovely green colour and started to go lime. Too much nitrogren still in the soil? Or Just a deficiency? They have recently been fed 1ML fishmix and 2ML Bloom.

Older leaves are yellowing, brown/red rusty spots, dying tissue, red stems.
Older leaves have brown/red rusty spots and looks like dying tissue in between the veins. Burnt tips, and yellowing leaves. The soil was really dry and my PH meter was 0.4 too high. I gave each plant 3L of water with EC: 0.0 PH: 6.4 to check runoff. Runoff was PH: 6.1 EC: 0.8
