Some pics at day 60
100W of LED is a lot for clones, way too much, even 50-60cm away.Something is happening with one of the clone of the Sowahh#2, it doesn't branches and has no new growth despite her leaves having grown a lot, it's the first time I see a clone doing this and I don't understand what's happening. It was a very small branche when I cut it from the plant and it had nice roots when I posted it but only the leaves have grown and took a beautiful shade of dark, shiny green but no branches and no apical meristem growth.
Is it possible it was burn by the light? The clones are under a Mars Hydro 100w LED, their smallest light who is not dimmable and those 100w can make quite a lot of ppfd. The plants are about 50/60cm from the light, I think it's far away to not damage the fragile young clones.It's just a supposition but I don't see any other reason for this clone to not perform normally.
Did some of you have already had this kind of problem? In many years of cloning it's a first for me.
