Wedding Cake nute burn or possible P deficient with yellowing slightly down the edge? Also may have N toxicity with curling leaves? Blueberry also has slightly burnt tips, both plants have yellowing in the oldest growth. All in diary pictures. Thoughts? And how do I fix it?

Hi mate, I think it all looks good. Yeah It looks like one or two leaves have a little nute burn but I wouldn't worry about it too much. Rest of the plant looks healthy. Good luck and happy growing.

Doesn’t look too bad! Dial back a bit on the nutes if you think your burning her. I always give my plants a hit of ph’d water once a week.

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.Leaves. Curl down

Clawing / StuntedNitrogen toxicity? Day 24, heavy soil and plastic pot, thought overwatering because the soil wasn’t drying out. Put lots of extra drainage holes in it and let dry out for 6 days. Giving plain water today. Will she recover or go to flower in this stunted state?a year ago

Yellowing, curling tips?I'm in the middle of week seven and noticing significant yellowing, curling tips, especially on the top colas. Is this cause for concern and what could be causing? Feeding low-dose (1/4-1/2 tspn/gal) of dyna-gro bloom and the plant is growing in MG soil. I know, rookie mistakea year ago

'Claws' on tips just after flowering started. Previous answers help - it is a bit worse. I keep a perfect VPD. What should I do? Flower wouldnt fI'm confused. For the first 3w I used LED as instructed 30-40cm, I had ~43cm,100%dim, everything was fine. When the bloom started yellow claws appeared and still there, maybe a bit worse, with 53cm and 75%dim. Mostly on BPP, one more plant showed her claws today aswell. 😓Leaves. Edges burnt

Weird Sugar Leaf BurningDoes anyone have an idea what happened to my leaves? They are trying up and burning for some reason but only 3 of the 7 that are in the tent. They are all clones from the same mother plant. At first I assumed it was too much light at 1200 ppfd but dropping it didn't help.a year ago

Slight leaf tip "burn"What do you think is causing this burn on my leaves? It seems to be quite common. and maybe nothing to worry about if it's this minute. but I would prefer to not burn my plants at all if possible. Could it be a sign of underwatering? Light distance? i have a dimmer keepin at 1000a year ago
