Doing research I thought I learned that yellowing leaves means nutrient deficiencies. A couple weeks ago I had several yellow leaves & come can find out my partner was still using the veg formula into flowering. We made the adjustment & we still have yellow leaves. What do we need to do?
We feed, feed, water, feed, feed, water. Could this have something to do with the problem?



Here's what I aim for when in flowering:
Weeks 1-4 - 750-950
Weeks 5+ - 1000-1600 Not sure if you have my book but there is a section on PPM which gives a bit more detail.
