That they do. The temps in the room vary. But I had limited choice as to where I could grow. At a high it gets around 85 degs, Not sure why the hall outside can be 5 to 10 deg cooler it beats me. At the lowest that I've seen 66 degs. It just started getting really cold outside aka hitting 32 at night 
. Cold for here at least. They are close to a window which has the blinds closed and a blanket and drapes over them. But moving them away was my next plan. Thanks for the info
The grow light can make a plant look washed out and yellow. Your plants look good so far. Are they flowering yet? Red stems can often mean cool temps however those red stems could be a sign of a phospherous deficiency comming up. If the red stays in the leaf stems then probably temps, but if the red continues to progress then a deficiency is there. Also keep an eye on how dark your leaves are, with a p deficiency leaves will have a purple cast to them. A ph of 6.0 and lower will lockout P. Luck
Hey there awry, my blueberry also has a purplish stem which I have been told (from a member on this forum who is also growing blueberry) that it is absolutely fine however the leaves have been turning yellow at the side which have now turned dark brown & the tips of the lower leaves are bending backwards at a sharp 90 degree turn. Just today I found that the higher leaves are beginig to to curl backwards but at the side. Any idea what this plant is lacking in or show signs of what? Please help if you can my journal thread is below:
Yep, some strains are more fussy than others and others are sturdy as hell and can handle nearly anything. Pay close attention to the red stemmed strain it may be needing an extra loving touch later.
red stems are always good
