I've got 11 ladies that will be four weeks old tomorrow. Five days ago, they received their first round of nutes. Using the same exact feeding schedule as my previous grows, same soil, same lights - never had this problem before. The only thing I've changed, is the water.
All of them seem to be yellowing, the largest leaves only. A couple of them also have coppery spots on them. I've looked at the deficiency guides, and cannot figure out what's wrong.
Three things I'm considering:
1) The PH was too high for about a week, week and a half, due to me trying to save a few cents, and buying drinking water instead of the purified water I was getting before.
2) I wasn't paying as much attention the past week with the Holidays, and they grew up enough for several of them to experience some damage from the lights (CFL's)
3) A few Box Elder bugs seem to be living on the plants (although research indicates they don't attack houseplants, no specific info for MJ plants)
Could one (or all) of these things be the reason for the damage I'm seeing? If not, what else could it be? I'd like to stop whatever it is before it gets worse!
