@Crazydaver,I think that you might be feeding a little bit hot for 2 weeks into Veg. In Recirculating Deep Water 💦 Culture you only need a fraction of what the nutrient labels say. I start at 25% of the recommended amounts on the label and increase 5% each week throughout Veg.
I am 5 weeks into Veg and I am at 475 ppm. I have found in RDWC that less is more and I have had much less issues running much lower ppm’s.
PH range looks good. I’ll let mine drift between 5.7 - 6.4. I would back off the nutes a little bit and see if that cures the issue with the leaf curl.
