You need calmag, I imagine. Or you have a severe lack of micronutrients like iron, sulfur, etc.

Leaves Sad
Guys I'm a little worried and for a few days I've seen them falling and sad... I checked the ground with water RO + CalMag EC 0.3 Ph 6.4.... The outflow of my soil gave me Ph 6.6 EC 1.9 values on average! I fertilized three days ago with EC 1.8

New growth and top leaves have some discoloration. Could it be light related, or maybe a zinc deficiency?
She has been flowering for about a week now and showing some pale spots. At the start of flower I turned the light up from 200w to 300w. Light is currently at about 20" from the canopy. Plants seem healthy otherwise, should I be concerned?

Yellow centre veins fan leaves
Yellowing of the inner vein of fan leaves only. Also sporadic yellowing and blemishes of whole fan leaves but only some, others fine nice and green. All bud leaves and buds don't appear affected. Is it just that she's nearing the end of her life cycle? Or over water/over nute?

Yellow Burned Bud Leaves. Purple Calyxes. Red Stigmas. Stunted?
As u go from top of canopy to bottom, the leaves get darker green and less burn. Lamp is at top of 3ft tent, 10 inch above canopy. Feed is at 1.3EC/6.1ph. Runoff EC climbs, then I FloraKleen flush about once a week. So is it just light burn? What you see? Is she stunted? Thx.

Why are my leaves turning yellow?
I have stopped giving it nutrients since I was seeing potential nutrient burn. However, I am still seeing some yellowing in leaves, some leaves also have yellow spots. What could be causing this? There might be some white flies in the tent.
