How much are you feeding her because to me it Looks like underwatering buddy or air drying roots that are too close to the intake! Had the same problem a long time ago! I can say it’s defiantly NOT nutrient burn or nitrogen burn or anything to do with nitrogen! Especially when your in bloom! Try and use some calmag or compost tea to se stress the roots and replenish them! Best option promise

Yeah definitely Nutrient burn or fertilizer burn is one of the most common beginner cannabis growing problems. The yellow or brown leaf tips are caused by too-high levels of nutrients at the roots, which disrupts the flow of water through the plant and causes the symptom of burnt tips on leaves.

Plant has nitrogen toxicity. Give a flush and lower the nitrogen in your feedings.

Starting Training I'm currently worried about my older plant set that seem to be constantly having the leaf edges curl and seem to be a little droopy and a little too dark green. Also I feel like I should be doing some sort of training. I would love to have some feedback on what you all think. ✌️

Leaves curl on upper new growth and mid but not lower.I’m using the canna coco line except boost, looks like phosphorus deficiency. I just lowered my a and b 0.7 ec and added 0.3 of pk for a total of 1.0. Is this phosphorus deficiency and do you think my changes will help. Leaves are a little dark shinny and the shape is odd.

Too Much Light?Top looks yellowish, more so IRL than in the pic and the new growth is kinda taco-ing. Just under 24" from the light, 78F and using Photone the DLI was at ~30. I don't really trust that app but if it's even sorta accurate, 30 might be high with no CO2? says their charts anyways.

Leaves are curling up The sugar leaves on one of my plants have curled up, I was wondering if this could be a humidity issue or maybe a temperature problem. Can this affect the plants yield as it is approaching harvest time.

Curling new growth All of my new growth is curling a little bit. I dont think it's N toxicity, but it's also probably not heat because all of them look like this. Is it N toxicity or something else? Thankss

Yellowing between veins on 3 of 4 plants, and curled tips - 27-29C in tent - Just heat/light stress or something more?Only on 3 out of 4 of my girls, see 1 pic of sad girl and 1 pic of happy girl.

Looking droopy/yellow due to light burn?Looking like light burn (most intense from the top) and maybe overwatering? I am trying Nectar for the Gods #4 soil for the first time, and I just put it in a grow bag and put the clones in it. Unsure if I was supposed to prep somehow beforehand.
