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

Both,
Water less but more frequently, next time mix for perlite into the medium so it won't have this issue. and feed less N in the irrigations.
Good Luck!

Curled up leaves on day 7I started a plant ten days ago and from the 7th day some leaves started curling upwards.
I flushed the soil one day before planting the sprout and watered it again on day 9. I use the Fecida 600 lamp 16/8 day/night.
Does someone know what could cause the curling of the leaves?Leaves. Curl up

CuppingOn the right plant in diary pic it shows slight upward cupping on the edges of a few leaves. There are a couple of others on the other side. But 95% of the leaves are fine. During my first try at LST I broke the main stem by 70%. I think this caused the cupping?Week 4

Magnesium Deficiency ? How can I fix it ?got a little deficiency (maybe burned? but I think not).
I'm pretty sure it's magnesium's deficiency, it happens after a flushing. I added 2 times the last 2 weeks a little bit of CalMag (BioBizz, but ive bought it 2 years ago, maybe it doesn't work well idk).Leaves. Curl up

Twisted leafs inner partLeafs are twisting but mainly inner part. See the photo. And it does not progress. It stayed at the bottom of the leaf
I assume three factors:
Wind
Excessive humid
Cold nights
They got Nutes at all, only from soil (pragron lightmix)
I would say shity PH, but i check it every timeWeek 3

Started LST but now plants look a bit sick?I attempted to do LST but I think I've maybe started too early as some of the leafs started to wilt kinda bad afterwards. Was careful not to break anything. Edges are curling and have discolored. I have a feeling they're a bit short too?
