Hi all,
I have a problem in my seedling room that I've never seen before - flecks of lighter coloured green on the leaves. After quite a few years of growing a certain strain, I'm finally letting that strain go and am introducing a new strain.
I planted the seeds for the new strains 11 days ago. The temp for the seedlings is 25 degrees, humidity at 70 percent. They're in Biobizz light mix soil and have had no nutrients yet, just water. There's no pests anywhere. The plants are growing taller every day, so not stalled or anything. There's also some slight twisting of the leaves of a few of these seedlings.
I just can't put my finger on why I'm getting these flecks - the only thing I can think of is that I use high light intensities - The seedlings are under a 600W halide at 20" (lowered from 24" at the start). The old strain has always been fine at these intensities, but maybe it's a factor for this new variety?
Here's some pics - I'd be very grateful if anyone can help.
