Well said. I need to find out whats wrong in order to learn.
Its genuine light drom diyuk. They are certi Samsung light strips.
Not autos, I run my veg cycle under 24h flip to 12/12 for flower when ready.
60x60x180. Temp between 22C-26C.
I'll up the calmag on my next fed is due tomorrow.
Right, powerful light then.
Ok, you never said how high it is above your plants, but been its 150w over 2x2 its too much.
That would be great in flower at 18" above plants, but its too much for this stage.
Reduce your hours of light to 18h
If you can dim then dim it to 50% , raise it to 24" if its lower.
If you have the option to lower extraction then do that and try and raise the temps to 80f.
If you cant do that then and have no other way of keeping it warmer then obviously dimming the light will lower the temp due to less wattage, so to avoid that as a last resort run full power and raise the light much much higher.
