Could be it wants a bit more nitrogen. Your balance is 4-4-4 so you could use a calmag nutrient with more nitrogen in, a lot of cal mag products have 2-0-0

Dying leaves I think it's a nitrogen deficiency causing me to lose some leaves earlier than I hoped, What should I carry on doing from now on? Last watering was 0.5ml/l of Grow, 2ml of bloom and 1ml of CalMag, just recently fixing a calmag deficiency after not having any(ran out).

Yellow discoloration again I'm annoyed by having to post another question but oh well. Yesterday evening I increased the PAR from 370 to 400 in center. This morning the top fan leaves were pointing straight up and so I raised the lights a little. I later looked and saw discoloration. Light burn?

Yellow spots on bottom leaves.Starting to notice big brown/yellow spots on the bottom leaves only. Plants look healthy at the top but not happy(not praying and look droopy). I water every 3/4 days so it’s not a matter of being locked and Calmag is also used. Can’t figure out what the problem is here.
