Hi there hoping someone can shed light on a problem i have encountered.
growing Nirvana Northern lights, 45W 6700K CLF inch1/2 away, small 12v fan blowing on it from some distance.
Growing soil and coco, previously had no troubles with this combo, and as Northern lights is apparently a hardy strain wouldn't expect these problems.
Planted 2 seeds, lost one other was going good but now growing concerns about this one too.
I lost first one due to there being a really really thin section on the stem, turned brown and shrivelled. Now, that one stretched a lot as i didn't have a light at the time, I planted the second when i saw this one wasn't going to make it and this second one didn't stretch at all, was growing really nicely and rooting like mad.
But now it seems to be developing a similar problem to the other one but no where near as bad.
So wondering what the cause of this thinning could be?
I have considered stem rot, and i now keep the current baby very dry around the stem and turned the fan up a notch, but still really quite wobbly and got purple tint to the area just below soil line.
Temps fall lower than they should do at night for moderate periods, could this be the cause?
Help would be greatly received don't wanna be losing another one.
I should've taken a picture of the first one but i put it down to stretching didn't expect a similar problem again, and this time the camera i got really wouldn't help much.
Many thanks RIU people
