One of three plants curled its leaves.
AutoAutomation
started grow question 5y ago
One of these three seeds seems to have suffered a bit, but unsure why - the conditions have been pretty much identical from what I can tell. The first set of leaves curled quite significantly but the new growth seems to be ok? Any ideas?

answered grow question 5y ago
is this plant closer to a fan then the others ? could be simple wind stress but curling of the leaves usually indicates some sort of heat stress.

Why are the sides curling up? Question not about them pointing down but only about the sides curling up and very small brown points
What is this? Sides r curling up. Day temp didn't get over 23 degrees night temp is +- 12 so I don't think she got too hot. Points bit yellow Saw this yesterday evening too, today at 1 plant a little bit. They're probably pointing down because of the low night temp so that's ok

Curled leaves and brown spots
Please help! My Acapulco Gold suddenly showed leaf symptoms today. Shouldnt be a lock out, I always water with drain and use lower doses than the BioBizz chart recommends. Used Molasses two days ago, could that be the cause? Its the only plant that shows this signs.

Bud rot?
Can leaves be an indicator of bud rot without seeing actual bud rot? Day 65, day 35 of flower. Looks bad...question really isn’t what I can do from here, I think I need to ride it out and harvest early. But is she a lost cause or likely candidate for bud rot?

Nitrogen toxicity?
This plant hasnt had any liquid nutes since been tranplanted 3 wks ago, i did however lightly foliar feed 0.5ml/l of bio-grow 1ml/l bio-heaven and 1ml/l cal-mag mixed with 1L spray bottle used over 1 week. My other plant looked deficient and bounced back. Could be anything else?

Cotyledons curling upwards - the others didn't do this? :(
I'm not sure what's going on! The two others didn't do this. I'm using ViparSpectra XS2000 at 24" distance and 50% intensity.

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. ✌️

First time growing/Need help in late flower
Over the last 9 days my plant has gone from happy and healthy to sugar leaves pointing straight up near the top of plant and drying and curling up on the lower levels. Is this from too much light or did I over feed late in flower? First grow/ no diary. Can I save or do I chop?

Guess on what this is?
Unsure what this issue might be. PH seems in check going in and out. Getting mainly Fox Farms nutrients - got very weak doses of B-52 and CalMag a week or two ago. The other two plants are fine.

Yellow crispy burn spot leaves
Does anyone know what could be causing the curling upwards on the leaves and burn spots, Yellowing as well? They're 7 weeks into flower and have been fed fox farms nutrients each other watering the whole grow until last week. The past week I have used plain water. Ph&PPM fine.
