they look fine, but just let em dry out a little more each time before watering if you're concerned. Definitely step up the container size, those roots love all the space you can give!
These 3 moved into their long-term homes today. The roots sure have a ways to go before they'll be able to reach their new reservoirs. They sure look puny in the big pots compared to the 16 oz starters. #1 & #2 are in 2.5g's, and #3 is trying out a 5g.
Yeah, passive hydro, drain to waste, aka hempy buckets.. My nutes are mostly the dyna-gro line/schedule with a couple of supplements. These 3 have only recently started on low strength feedings.
