Stunted fem seedlings

@Experimentgreen have given then a dose of cal-mag nutrients a week ago other than that waiting on PH soil meter used miracle grow soil

@HarbingerOfHarvests If i add 40-50% perlite in my soil in the 10 gallon that would help?

Hey She looks a little small for the 10 gallon yet.... maybe build her up a bit more. Try some root strengthening, Superthrive and a more roots type product really helped my slow babies. If you do go to the 10 gallon just be very wary of overwatering...even with the fabric and fast drying it might be a bit irritated in the first couple weeks. Have you been giving any low low doses of nutrients? Even just some kelp powder might be nice since it's pretty gentle. Ph is good? Those are the only things I can think of.✌️

too much water.. Is on the basis the roots would be so saturated with moisture.. That they stop be able to "breathe". There is a balance.

Soil looks rather barky... Could be a hot mix.. Water over nutrients for seedlings 100%.. Nutrients kill seedlings and slow em down a lot... over watering is common as well but think in terms that the plant needs water to grow period at all points of life and for all life functions... Water is the Blood of the plant.
