I've been following the water feed water plan so far. Im just entering week 5 of Flowering. Im giving 5ml of Cal Mag every water and feeding cycle. Im feeding with Fox Farms Nuts at a little over half dose on my last feeding but the yellowing continues to get worse and now Im getting some spots. Im hoping this is because the plants are using all the nutrients to create buds but I have no idea as this is my first time. After the last feeding my numbers were: Crystal: 6.2 ph 1630 PPM Amber: 6.3 ph 1528 PPM Raven: 6.6 ph 1200 PPM Trixie: spilled her sample and was unable to capture more Pic 2 Pic 3 Any help is always appreciated. One last thing......a little late but God Bless America. We can grow because of the brave men and women of this countrys military keep us free. Thank them.
