Yeah so maybe this water only route was too good to be true. Nah I've had a slow start in this new medium but honestly I think its because I've been using water that I've only pHed once and its taken a couple days to get through it all before I have to refill the sprayer. Yeah all that yellow made me think I'd overwatered, which isn't hard to do when trying something brand new, but I've backed off the water and the only thing I can think of is that the pH must be out of whack. All pots got the same medium mix and ratios of amendments. Next week I'll topdress one of each strain with Dr Earth and the other with Happy Frog fertilizers. For now I am going to work out the pH issue and try to get that sad looking seedling back on track. Its crazy how much smaller these are than the last one. Looks like this whole batch is gonna be small but I'll just have to learn as much as I can this go round and get better next time. We shall see...
