So, they streched a lot, I had to bend severely. And so quick, like 5 cms in a day!
They touch the light, I had no more room...
I did a late FIM on 2 of them.... emergency I finally found a way to get the lamp 5 cms higher.
Lukily it has stabilized but still, top of the buds are at 5 cms from light!!!!
That's why I decided to drop the power at 50% and I lower the day light to 16 hours.
