The first two weeks I kept the same res, but I am going to start doing every week again. My last grow I did every week and I got lazy the first two weeks this time around. I'm due for a change, so I'll flush for a day and see how things are and go from there. Thanks for the advice stinky!

Oh, and my rockwool is the small 1" (I think) cubes surrounded by hydroton and I am feeding ten plants.

The edges are crispy and the new small leaves around the buds have yellow, crispy, turned down tips. The guide I read said a little P deficiency in flower is normal, but if P is what it is, I think I have more than a little. What should I do? PPM is 1150, pH is 5.6, double checked with liquid pH kit. They are starting Week 4 tomorrow. The last pic is what I would say is the worst looking one. Rating: 5
