It is potassium deficiency just starting. If you have been giving a lot of Nitrogen and have some leaves clawing tips, then it is blocking the K from being absorbed. You can give some more potassium to your plant. This can be seen when a plant is switched to flowering, so provide more K for stronger flower production.

It looks like lightburn to me but at 75cm that shouldn't be possible (are you sure the light is that far away?) so maybe it's nute burn rather, maybe you just need another fan to move the air round more or better extraction to remove warm air more efficiently 🌱👍

Is this heat light burn? HPS 600w at 20cmIs this light heat burn?? These are all buds at the top of the canopy and they are the ones nearer to the lights. I have 2x600w HPS, one with a cooltube and the other just with the wing. The possibly burnt buds are the ones under the wing (just 20 cm).

Calcium excess, which led to potassium deficiency? Or just light burn? Or both? What's wrong with my girl? Please, help.I've been giving her BioBizz in accordance with the schedule, including CalMag. Using tap water (250-300 ppm). So my only guess is calcium excess, which led to potassium deficiency.
However, only the main cola is affected now. So I also suspect light burn.
What's your opinion?

Did I do the right thing? Pls check my update on this week!Can my Growmies check my update on this week please? Ppm shot up and I noticed nute burn. Weird bc I have only added water since last week. I cleaned the pump, removed air stone and lowered ppm. Definitely seems like too much nutes - hoping they’ll perk up.

They were slightly overwatered, the soil PH of 7.1 to 7.3, lacking phosphorus, maybe magnesium to. Branches from the sides are stretching, but I noticed thet lower leaves started to turn yellow a little at both. If anyone knows good advice to help them out, I would be grateful.😅

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?

Deficiency?So I noticed this yesterday and I'm struggling to figure it out. The symptoms only appear on a few leaves of only 1 branch. Nothing about the environment or feeding has changed. A recent flush of plain pH'd water showed slightly acidic soil but not too crazy. Bottom feeding with

Yellow/burned tips & curled leavesI have an issue with some yellow/burned tips and curled leaves.
I already suspect that mainly is from light stress but could also be a nutrient deficiency?
I´ve raised the lights the max I can and keep it at 80% for 20 hours.

Potassium deficiency?Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

Maybe PH Lockout?Hello everyone, can you maybe help me? My Black Cherry Punch has some kind of problem. I suspect it’s a nutrient lockout caused by the pH value. I flushed it two days ago, and the drain had a PPM of 1000 and a pH of 7. The plants are at the beginning of the 2nd week of flowering.

Burnt looking seedlingWhat's going on with my #2 seedling? I thought it could be light burn and raised my light by 4" but the odd coloration on the tips has gotten worse 18hr later. It also doesn't seem to be drinking whats in the coco yet so I'm cautious about feeding.
