To fix it, go to quarter strength and the extra run off should start rinsing the excess nitrogen out of potter.

i had this new seedling directly under a 400 watt hps at about 2-3 feet and noticed the leafs curling up. I removed it off an elevated tray thereby increasing distance and moved it to the periphery of the hps. is this a problem due to excessive heat or light or something else?

Twisted, yellow/brown tips.
Hi, My plant has shown signs of a nutrient excess throughout its complete cycle. It keeps to the tips of younger the leaves that have a tiny twist in the end. I don't think it's the light as it also affects leaves in the lower canopy. I keep on flushing but nothing changes.

Two part leaf question.
Two parter 😁. Are the new leaves on my plant deformed or am I being paranoid? How can I stop leaf curl? At first I thought it was a light/heat issue but both light and temps are fine and it doesn't feel too humid in there. See more pictures in my diary.

Yellowing, curling tips?
I'm in the middle of week seven and noticing significant yellowing, curling tips, especially on the top colas. Is this cause for concern and what could be causing? Feeding low-dose (1/4-1/2 tspn/gal) of dyna-gro bloom and the plant is growing in MG soil. I know, rookie mistake

Surplus or deficiency?
Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

Any idea why the leaves are curling inwards like they are in the last two photos? Is this because it's too hot, or am I giving it too much water? Should my fan be blowing on the plant itself, or the 150-watt light? Thanks.

Leaves yellowing and curling
Leaves seem to be yellowing and curling upwards. Is this under watering or a deeper issue such as nitrogen deficiency?

What can be the causing of the leaf curl upwards beside the obvious? like heatstress, waterdrops or maybe roots? seems also unlikely to me she has the same feedings as the strawberry. my other plants are fine. more info in the text. Thanks in advance

Leaf tips curling on top
What’s causing the leaf tips to curl? I moved the light away and reduced the power to 75%. Please advise on how I can address this. Looks like her growth has changed, a bit slower and a bit lengthy.

Do I have an (Mg) issue?
Leaves turn light, have black spots and 1 leaf rolls in upwards. It got Epsomite with every watering so I guess it's not a deficiency. Last time there was not even a drain. So maybe nutrient absorption is blocked? Should I flush? Is it to stressfull for this autoflower?
