Seedling advice
Hi, my light was at 60cm with an average humidity of 70 degrees Celsius. There’s slight dryness around the tips, yellowing, crispness. Remedy thus far: I moved the light up to about 75 cm, it’s a 100W led. Humidity also dropped to about 60 degrees. Any advice to remedy?

The tips of the leaves turn yellow
The tips of the leaves turn yellow. I don't know how to identify the problem, is it the mycorrhizae that make them hungrier? Or do they just have too many nutrients?

Excess or Defiancy?
Some leaves from the top of my biggest plant, Frisian Dew, turn yellow and brown. The others don't show this behavior. The plant is in week 22 and still needs approx. 4-6 weeks until harvest. The plant pot is fully rooted up to the surface.

Spots on seedling leafs
How do my Fastbuds Six Shooter Auto seedlings look? (12 days since seed in soil, BioBizz Light-Mix). Didn't fertilize yet, but there are some lighter colored spots on the leafs (also new leafs). What can this be? They get 123PPFD at the moment, and sometimes reaches 26,5°C.
