brown tips on some leaves

handamanstarted grow question 5y ago

first week of flower, only one plant out of five affected, only couple of leaves close to the top affected (up to 5 in total) - my assumption is 1. too close to light (I have 40cm between 400HPS which seems enough), PH problem or deficiency (potassium?)

Hi mate, looks like a little heat stress. I'd lift the light an extra 10cm and see if she improves. I hope this helps, good luck and happy growing...

Ciao a tutti. Ho un problema alle foglie più giovani superiori. Stanno avendo delle bruciature e non capisco se sia un problema di troppa luce oppure a causa della carenza/eccesso di fertilizzante. Qualcuno può darmi un aiuto ???

Is this possible nutrient burn?Sour Kush Day 24 (Coco/perlite) - brown tip appearing on lower fan leaves. I suspect it's nutrient burn. Flushed with 900cc PH neutral water, lot of runoff, PPM was 391 (PPM in 495). Should I cut back on feeding by diluting the nutrient water or by watering less frequently? TY

Fan leaves getting burned in week 4 Earlier my plant suffered from nutrient burn as I fed it nutrients by mistake in week 2. You can see the pic in earlier weeks. If you see Week 4 Day 27, the fan leaves are still getting burned, this is the topmost fan leaves, also some random fan leaves below are suffering?

Slightly Brown Crinkly Tips Dose anyone know what could be causing this browning at the leaf edges? It is a bit dry and crinkly to the touch. This is only on the bottom two fan leaves, and only the very tips. All the newer growth looks fine. Nutrient Burn maybe? Should I be worried, or adjust anything?

Some brown and crispy tips to buds. I think burn from crazy hot sunny days after all the rain/clouds over last couple weeks. I have cut off affected part an inch below, and no sign of worms and doesnt look like rot. Any suggestions are appreciated.

I probably have spider mites on my plant. Yesterday I sprayed it with Maag oil. Today I bought an organic product and sprayed it on the plant. Are the discolourations on the plant caused by the mites or burns due to increased light from the drops? Or a lack of nutrients?

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
