day 37:
I suspect my plant suffering from mineral deficiency (mostly Iron), because I noticed dark color leaves and light green veins, also lower fan leaves continuing turn yellow.
day 38:
I found out why my plant is experiencing mineral deficiency - because high pH water.
When switched out on BioBizz (organic) over GHE (mineral) fertilizer, I stopped pHing water because BioBizz fertilizer's manual said that you shouldn't adjust pH till it have no something weird values like 9, but my water have 7.5 pH.
As I see consuming of minerals was blocked because of high pH water, so for today watering I pHed water with a few drops juice of lemon and it have been around 6.5 pH after added fertilizers.
I hope it'll will fix mineral deficiency.
Watering (500ml) + (1ml/l Bio-Grow, 1ml/l Bio-Bloom, 1ml/l Top-Max, 1ml/l Bio-Heaven).
day 40 - Watering (600ml) + (1ml/l Bio-Grow, 1ml/l Bio-Bloom, 1ml/l Top-Max, 1ml/l Bio-Heaven)
@soma666 Yeh mate the oldest leaves will usually die off once the buds start developing. Don't pull them off until they are yellow as the plant will utilise any energy
before they die
