Flowering Help

Hey guys and gals im going into my first week of flowering and wanted to know what level my PH should be? Also ive herd that when you start your 3rd week of flowering you should increase the amount of nutes the label says to use, is this true? Appreciate any help...

pH should stay around 5.8 always. As far as nutes go it depends on the strain. A lot of nutes tell you to increase the bloom formula after about three weeks. Just watch your plants. Do they look healthy, are they growing rapidly. Adjust if not.

5.8 in bloom or in bloom and veg?
