Hi Growers, my tent has recently hit some low temps at about 15 degrees lights off, I have now improved the temps by a few degrees to about 17 at lights off. Purple is showing on my stems probably caused by cold but purple also showing on the back of leaves? Should I worry?

I would say that it is not an issue but your plants are young so yes it is a problem . The pirplelish colour is due to the low temps and the fact that the leaves and the petioles turns purple is not uncommon with you temps, the new growth will look a the same if you have no way to change your temps to something higher. Any temps under 17 and higher than 30°C can slow your growth. From what I can see you are now at the lower temps limit ( don't get back to 15°C ). You did worry enough now you can relax 😊

Yellow and purple leavesI stopped feeding beginning of the week because I had yellow tops on one of my buds. I think it is causing yellow leaves. Does that sound correct? Also I am seeing sort of a purple colouring on some of the leaves. Is that okay?Leaves. Color - Yellow

The insides of a small number of future bud sites are showing some strange purple discoloration. My initial thought was that this could somehow be mold however under the microscope it is very purple. Any ideas or suggestions would be greatly appreciated. (see images week 11)Week 11
