Yea for sure, I actually checked the ph and it snuck from 6 to 7.5 from the rockwool or the nutrients (at 600 ppm) during the first watering. Looking very good today, much bigger leaves getting 3rd set. Two of the caramelicious had weak stems and I had to give them a brace...currently fans blowing on them to make the stems stronger. I will update tomorrow so that you can see their progress, those dirty sluts!
