Hallo everyone,
I'm doing my first grow in my green house. But my seedling have totally stopped growing and leaves are getting yellow.

What should I do, the other plants in the green house are doing just fine.
Could it be bugs, heat, nut, to less sun etc.

I live in North Europe.

The strains are LSD & Meth.

I tried to feed them some very weak nuts. But it dose not seem to help.
I don't know if it the pots that are to good at keeping them wet they take so long time to dry out

Adding pictures for clarity ...

Nutrient uptake chart for hydro:

You would want to pH your nutrient solution to 5.8 +/- 3

In soil, it's a bit different ... your soil should have a pH of 6.5 +3/-2 for best results.
