Deficiency late in flower
Mystummyhurtstarted grow question 3 years ago
I am having an issue with a possible deficiency but it came so quickly. Does anyone know what this is? My growth seemed slow before and I noticed the leaf tips turning. Now they’re crinkling up and dying…

Looks a lot like heat stress to me. But since I see drooping on your other plant I guess you underwater a little. The combination of heat and low humidity is catastrophical. Happens real fast. Had the same issue. Raise your lamps . Find ways to optimize ventilation and humidity. (Fiddle with the fan and add humidity by adding wet fibres)

Are you certain your temps are staying below 75?( Got that from your diary).
My last grow looked exactly like this at the end of flowering die to heat stress. My temps were in the 90's, as soon as I fixed my airflow issue there were no more curling leaves.
It can get really dense in there and the fatter the flowers the more heat will stay trapped in the tent.

Dude those leaves look really bad, it could be bud rot. Try removing one of the leaves and see if it comes off super easily at the stem. If it does then the bud is likely rotten and ull have to cut it open to confirm. If bud is rotten harvest ASAP and toss all rotten buds, u cant smoke that it's toxic.

Organic soil 0.1-0.1-0.1 60% soil 40% perlite soil is pretty damn dry on topThe girls seem to be doing ok, little bit of curl up on some of the leaves, which indicates I over watered, humidity is usually 40-50%. I water 1 time per day with a mister, it's only been last few days that leafs curl up. Is it time for nutrients?. They are 10-11 days old.TIA

Leaf Symptom DiagnosisThe leaves (pictured with weird wrinkles and crispy edges) are showing some form of stress. Theory is that they were dehydrated from the overly salty medium, but I'd love to hear from a more experienced coco grower about if and how I should intervene to alleviate the stress.

Brown yellow leaves?Can anyone help me? I had this issue with my last early Miss and thought it was a cal mag deficiency. I tried to adjust it last time during flower but it didn’t help. I really only notice it on one of them so far but I would like to fix the problem sooner than later.

Upward curling of leavesOne of my plants has started to have it's lower leaves curl upwards & started to go a yellow tint that's harder to see in my images. Yellow tint is starting higher up as well I think, but the curling is only on the low leaves. Is it nutrient defficiency, heat stress, wind stress?

Everything seems to be OK except one thing (week 3). I thought using the greenhouses at night made this, but it doesn't. When I check the plants early in the morning, their leaves are slightly curled upwards, just along the edges. As the hours go by the leaves flatten. Any clue?Week 3

Weird looking seedlings? (uploaded vid)My seedlings, especially Seedling 1, look kinda weird to me. Seedling 1 appears to have some weird yellow spots here and there and the leaves look cut? They just look really weird and not like normal cannabis leaves, both seedlings have their leaves going up at the corners.5 years ago
