Looks like Heat and overwatering + calcium deficiency possibly caused by Potassium excess.

Still having a issue 5 days into flowering and my wedding cake has gotten very yellow looking. It hasn’t seem to slow down any but I’ve also applied some nutes yesterday but not heavy as I’m swapping over from veg nutes to bloom. Any advice? I moved fans and lights 18”+

Yellowing on GT and clawing on CB
I'm seeing an issue with Ghost Toof. The lower leaves are burning it seems. It looks like it could be a K(Potassium) issue, or possibly nutrient burn. Also, Chem Bear seems to claw quite a bit. I don't think I'm overwatering... so maybe a Nitrogen issue?

Yellow leaves
Hello, take a look at the pictures please. Leaves are turning yellow and curl. Is this a N burn, or a deficianty from some mineral? Or is this nutrient lockout? Plant does grow well!

Noticing my very bottom leaves are turning yellow. Should I be concerned with this? Any idea of the cause? I haven’t used any nutrients yet.

Is this yellowing normal? Probably because of LST?
I am growing my plant with LST and some of the lower fan leaves have been moved down in the shadow. Is this the reason why those leaves are getting yellow and dry? All the rest of the leaves look very green and healthy by the way.

Lower Leaves Yellowing
I have noticed that a lot of lower leaves are turning yellow. Theres nothing special going on, it just fades from green to yellow evenly. I am feeding it Veg nutrients 3:1:3. So it can't really be a Nitrogen deficiency right?!

Yellow dot on the leaf.
Yesterday I watered with fertilizers. The dosage is 0.8 grams per liter. PS in the area of 5.5. The instructions say 4 grams per gallon. 1 gallon = 4.55 liters. Everything seems to be correct, so I do not understand what the problem might be.
