nutrient ppm, how much?

how high should my ppm be with bc boost/bc grow? 1500ish should be ok for a month in?

Yeah that sounds about right... just keep inreasing it slightly everyday until you see the tips start to burn then back it off a touch.

I very rarely get that high with my PPM. Maybe 12-1300 at peak time. I've read and heard ppl getting into the 1800's

I run around 2000ppm at the moment... it just depends on your delivery system i suppose.

let me remind you less is better than more,you never should feed enough to start any burn,that equals less bud and less potency.ive jnever used bc bud and bloom,but with an 2 part,this is my basic tds readings but you must also remember each strain and individual plants in a strain can use more or less nutes.

0-4 inches water only( as well as rooted clones till the second week under bright lighting
4-8 inches 700 ppm
8-13 inches 1000 ppm
13 and up 1100-1200 ppm

these are all with ro water testing 5 ppm,if you use tap water include its ppm in those figures!

hope this helps you and have a good grow.
