so far i just have some 13w cfl reptile bulbs for UVB, they shouldnt be as agressive.
Idk, maybe if you increase the UVA portion they will be able to take more of UVB from your T5.
Looks like yours is doing more or less just UVB, a good portion of UVA is normally needed too, otherwise they cant take the UVB.
With uvb is it the heat or radiation that’s burning the leaves

It’s the uvb. Uvb causes damage to the plants
I have this reptile bulb that’s uvb that I never used may have to try that on some extras I have in flower...pulled my 2 4x4 table harvest they were set at 550 watts under some QB boards. After a week of hanging they are a little over 4#s. After cure maybe 1.5# per table. After all the years on and off growing with hps I’m really loving these leds. I didn’t do nowhere near my usual effort and still came out with solid numbers
