Jack is growing slow. It still shows some deficiency on the lower fan leaves but new growth looks good.
I mostly RDWC so the Pro Mix is a little new for me. I have been feeding the plant with a similar PPM of nutrients as I do with RDWC. I soak the soil when it dries out, about every few days right now.
I bent the main stem for LST. I want to control the height if it takes off in flower stretch and also to expose more bud sites on an even canopy.
I'll switch to flower lighting later this week.
Looks like calcium to me. Possibly potassium but that usually wont show until flowering. Hard to tell with the current state. But week 4 shows the start of the issue a lot better
