I agree doesn't look too be a issue. You could test soil ph using a run off reading or slurry test just to be sure you're with the correct soil ph range to absorb nutrients. If you've been phing water in happy frog your soul ph could be a little low. I use happy frog to start seeds. Transplant into 1/2 happy frog half ocean forest then final pots are ocean forest only. I use dry amendments and don't ph water. However phing early without top dressing still can screw up the soil ph. Those are 2 months old in 2 gallons top fed once. They are ready for transplant but I've been giving 9.3 tap water from the water hose and a boogie blue filter, no phing. I purchased the soil pen because plants kept looking sad for no reason. Using R/O water and phing soil tested low 5's I stopped phing and they turned around and looked fine. Once the organic material in your soil has been depleted you'll need to ph water if using liquid nutrients as liquid nutrients don't feed the soil and micro biology like organic material. Liquid nutrients just feed the plant and have to be phed to insure soil stays at the optimal level.
