PLEASE help ME!!!!

ph can easily lock out nutes needed for plant growth or starve them out

if your using a good potting mix there is no need to feed until after preflower 2-3 weeks 5th node or so
ph'd water
dolomite lime mixed in the soil before planting will keep a constant ph and eliminate cal-mag issues
keep your feeds low until you get the hang of it if your pot is 2-3 gals or larger it is easy to get monster plants on light feeds
