Jayann started grow question 3 years ago
All but one plant is showing some red/purple on the main stems. Temp drops to 66 which I did not think was cold enough to bring that out. Ph is on par with no issues. Calcium def? Worth adding cal-mag 5 weeks into flower? Only source of cal was in the lime in initial blend.

hey there Jayann, yeah the red stems, you're right, it's the first sign of stress. This might sound wierd because you dont hear this ever, but your CFL is probably a bit too close and it's causing this stress you're seeing. You can fix it with more dolomite lime or any other calmag supplement and by moving the light even just an inch further away. the plant should recover within ten days. Hope this helps ! :rocket:

All the plants look pretty damn healthy to me:+1: and from the looks of the leaves on all the plants it doesn't really look like a cal-mag def. My geuss would be the temps bringing it out. I have a plant in flower right now and night temps are the same 66*F and she has some nice purple/redish stems on the leaves so that temp can definitely make some color pop. Plus a lot is genetic as well. So with all of them but one getting red/purple main stems it really seems to be the temp. and the one that is not showing it could either be something genetic or that plant could be in a warn spot. Just keep an eye on it but I would say your fine and got nothing to worry about:blush: Happy Growing
