These are on my CBD workhorse plant so I've seen it a few times and know how they typically look.Thats hard to say as every strain is a different shade of green, but if it's greener and not yellowing it's an improvement. Dark green, as in darker than a strain should be, is quite often an indicator of over nitrification. Brix will tell the tale. Keep a close eye for yellowing. What does the water stick say?
Water stick on the flipped plant showed 10, 8, 6 on consecutive days but today is a 7 which suggests to me I'm heading in the right direction but likely not measuring it at the same depth every day. I think I'll stick some painter's tape on the meter at the level I want to read for that plant so I get more consistent.
I'm not sure what the measurement units are but I guess it doesn't really matter that much. More of a relative thing over time.
But, likely in another day or so it'll be ready for the top watering.
