To much nutrients dude. Water them with only water then start feeding and you will be fixed.

They are on the older leaves and they keep getting that faded yellowing starting from the tips. The pH of the run off is 6.43 and they havent been fed a round of nutrients in a week! I thought it was a cal/mag def but they haven't bounced back after a dose. Help please!

Veg Nute Issues
Has anyone seen any diaries that catalog a successful sick veg -> healthy flower recovery? I'm curious to see how sick growth transitions to healthy growth over several weeks. Current issue: a) LED intensity, b), N excess, c) PK def, or d) cal/mag def(rust on leaves top and btm)?

Upward curling of leaves
One of my plants has started to have it's lower leaves curl upwards & started to go a yellow tint that's harder to see in my images. Yellow tint is starting higher up as well I think, but the curling is only on the low leaves. Is it nutrient defficiency, heat stress, wind stress?

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.

Leaf discolouration. Nutrient deficiency?
Leaves are discoloured and clawed. Started about a week ago with yellowing of tips and clawing at top of the plants. Now lots of leaves are slowly changing colour. Thought it was nitrogen toxicity but my runoff is 330ppm. Are they deficient in nutrients?

Deficiency help
What deficiencies are these? I’ve flushed her, ph’ed her water and I’m giving her a good amount of nutrients - no nitrogen for the past two weeks I think. Is this just an age thing? I don’t need her to look perfect before harvest, but I’m afraid it’s affecting the bud maturity.

Sudden yellowing and discoloration of a e or 4 week cutting. I water it when I see the Coco getting a little dry. I make sure there is at least 20% of run off water. I watered with pH corrected water to pH of 6. I also add a small amount of canna bioryzotonic for their roots.

Yellowing leaves
Hey fam, Just ended 3 weeks of flower for this Banana Purple Punch Auto. A heap of yellow leaves basically appeared over night. I fed on the 13th with flower fert (has some N in it) and again on the 18th. This is the only plant that’s going yellow. What do you think?
