Las últimas dos semanas riega con enzimas y agua no más , para que las plantas vayan absorbiendo todo los nutrientes del sustrato.

Lower leaves damaged (macronutrient excess) or Top leaves damaged (micronutrients), may also have a little bit of N to spend but that might be one those blooms that come with N

Weird Sugar Leaf Burning Does 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.

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 1000

Plant issue Best guess as to what this is caused by? Only appears on upper half of the plant. Lower half is healthy and normal. Flushed with 5 Liters of 6.4 pH water stopped the progression

Leaf tips browned. What nutrient problem is this?Leaf tips browned. And some signs of burn/discoloration at the leaf side edges. Do you think it's general nutrients overdose? I didn't increase my PPM for the last two weeks, so I don't think it is a problem... Or Potassium deficit? Or any other secondary nutrient deficit?

Deficiency or Burn?I have used Happy Frog before with no issues. I am running my first 420 Fast Buds seeds and they seem to have nute burn for the last few weeks no matter what I do. Is this maybe a deficiency and not burn?

'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 f I'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. 😓

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 mistake
