She’s fine, let her dry out a bit! Also add some Magnesium sulphate to straighten her out! Cal mag her up! Mainly Magnesium though!

Theirs plenty of nitrogen though, see how the leaves are slightly turning? This is a sign of too much Nitrates/nitrogen!

LEAVES AFTER FLUSH
When I flushed my plants all leaves went looking down as normal, but now that they dried they kept that shape and the tips that are really dry (due to previous overfert) are curling all weird...is it ever gonna go back to normal? Is it still good anyways?

Let it grow or cut it out?
One of the seedlings isn't doing so hot. Should I just start a new seedling in it's place or give it more time? I've had a stunted seedling like this before in a previous grow and it ended up yielding a lot...

Upward curl
Hi Breeders, Elizabeth is growing well, but the bigger leaves are curling up at the edges. I already increased lamp hight and lowered to 18/6. Is it air humidity? Or too much water?

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?

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?

Leaves turning yellow/pointing up, stem turning purple
Having a problem with one of them.. all the leaves have gone very yellow and are pointing upwards. The stem is also very purple now. Any ideas what this could be? Other than a feeding of bud candy and watering here and there it hasn’t gotten any other feeding. Thanks!

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.

Is this nute or sun burn? What should I do to save my babies ?
I upped the nutrients to week 2 of veg state (biobizz) and put the light to 50% intensity. I put the light at 6 inches above recommended height (which is recommended on the Mars Hydro website for beginners). . IS THIS NUTE BURN OR LIGHT BURN?
