Both plans seem fine but not growing as big as expected.
Organic still seems more attractive than the mineral one, cannot see a real difference between them, hopefully at the end we will have some results.
The weather here is really crazy, we had up to 37 two weeks ago, This week we have nights of 10-12. I think that may be the reason why plants are not thriving.
Looks like they are having a great start.
I wouldn’t put those glasses over your seedling, you can get fungus on your seedling and it could die. Let them out in the wind, makes them strong an resiliant.
Good luck. 👍
