Why are my leaves clawing / curling downwards and dark green?
jokggastarted grow question 6y ago
I am noticing that all three plants have leaves that are curling down and specifically my Think Different 1 (right) is a dark green with some weird leaves.
Not sure if this is pythium, nitrogen toxicity, or light heat? Anyone have any idea what this may be and what I can do?

This symptom is almost always caused by an excess of Nitrogen!
Too much nitrogen causes dark green, clawing leaves and sometimes but not always burnt tips.
I’d back off the nutrients and just use plain water until you see her recover a bit!

It's a clear case of nutrient excess.
The excess salts have blocked the roots, and they can no longer absorb nutrients from the soil.
The only solution is to perform a root flush (2L of water for every L that the pot holds); if your pot is 15L, prepare 30L for each pot. I recommend taking them to the shower and draining all the water there.
Prepare water at pH 6. + 'Flush' solution (Final Flush from Grotek or Canna Flush) https://thgrow.com/es/grotek/3528-final-flush.html
Remember: Adding more fertilizer doesn't mean better quality.
Good luck, my friend!

To much nutrient.
Water them with only water and then start again.

So I noticed on day 6 she started to stretch, she was the leggiest out of all 4. I swapped out the cup as it had a surround on it for jug to improve light.
I think this has helped.
BUT her cotyledons are very dark green and curling down and under, and her top is smaller+darker??

When should I put the pellet in the 5 gal pot??I am currently growing a tangie'matic with "a pot for pot" grow kit. At first the seed germinates in a pellet. Then it says "put pellet in 5 gal soil mix after 10 days or when the third set of leaves matches the second." I did it after 10 days and this happened.

Hello guys,
This is my first grow and I need help. Leaves started curling downwards. I'm not sure whether it was overwatering, underwatering, or needed repotting to a bigger pot. I repotted it today to a bigger pot and crossed my fingers. If you know what's up please help!
ThanksWeek 5

Leaves looking a bit discoloured and wilting slightly, what could be causing it?Leaves are drooping a bit and slightly discoloured, especially when comparing it to the other plant. Also, a couple seem to be growing at a much slower rate, is this anything to worry about or will they catch up? TIA

Moist build up at bottom - overwateredI believe this seedling had too much moist. The soil was moisty when I filled the pot.
Somehow the pot feels very heavy now and seems there is a build up at the bottom. I made some airpockets to the bottom.
Should I wait or take it out and put it into a cup and dry the soil?

Leave Tips Yellow and Brown on New GrowthThe leave tips of my plants turned yellow and burnt after i gave them a bottled nutrient feed (organic). Unfortunately i failed to measure the PH of the Water (it was probably to high). This was one Week ago and the New Growth still show signs that something is wrong.

End of Cicle or High stress???Good morning everyone! First, thanks for the replies to my last question. 2 of my 3 girls are doing much better, but sadly one is still very stressed. As a beginner, I’m not sure if it’s normal end-of-cycle or if she’s still suffering. Thanks, Jack
