[stonedsmithy]

hey guys i noticed some of my plants leaves are goin lighter green on the edges,i not tooo worried yet cozz otherwise the plants are going pretty good was just wondering what it might be

yeah, it might be, but it almost looks like it might just be the strain...?
if it's not then it probably is just a very minor nute burn, just keep an eye on it, and reduce your nutes for the mean time, if it continues, then check out the troubleshooter in the 'sick plants & problems' section if you already haven't, but like I said, it's not that bad to make a big difference.. is it happening to the lower branches as well?

it is highly unlikely you would ever notice an MG symptom due to lockout as the plant would simply die first the PH range for MG is anywhere from 6.0 up to 9.0 Calcium abundance or shortage is more likely to present you with MG symptoms.

On the leaves that are yellowing around the margins...Is that brown clogage I see occurring in the veins? Also any brown growth on stem(s)?
