You got it! inside it will start to flower in 21 days or so... just went way back and saw that on some notes. I don't know about you but doesn't seem like ya want much veg nutrients. I don't know how ya control that with ff I bet you do tho...
If that’s the case Then if you’re going to use FF OF water with run off or you can use a different medium without the nutrients in it feed as they need it
