That sounds right and seems like it would be definciency not related to lockout.

Since it is eating and looks green otherwise, are you also feeding 50% cal mag dose? You could start by just bumping up the cal mag?

If your plants start to yellow a little, or show other problems, I'd think of pushing all the nutrients up from 50% toward 75%.

Please someone confirm or correct me if I'm wrong here. I'm trying to use some pretty fresh knowledge I've picked up, so don't want to be way off!

I stopped replying to this as I wanted to stop getting in anyone elses way trying to help. Did you get anywhere? See any improvement? Add Cal Mag or up the overall nutrients?

Yeah I hear that from everybody!! I was talking to guy about it my local hydro store he thinks it’s something to do with VPD. We have had really low RH in northern ca. I couldn’t get my humidity above 30 for a few days!! I know nothing about VPD

hopefully you narrow down your issue.

if growing cannabis is that scientific, I’m screwed. So hopefully not.

I’m in so cal. I was using a humidifier it found just by watering the plants was raising my RH levels to target range

18 watts 18 gallons of water.
Are the leaves rough when you rub them? I’m asking because the one pic the plant looks soggy wrinkled and droopy. If you ignore the hydro part, it’s possible to “overwater” if the roots can’t breath, adding more light would increase demand, just a thought I guess, any root pictures?
