using humboldts gravity during N deficiency?

Hello all,

just wondering for anyone who has used gravity or has experience with it, is it safe to use the gravity while the plants are N deficient? they are at day 38 out of 8-9 week flower.

you should be good just use half of what it tells you cause it can really screw up and burn your plants. other then that make sure you flush really good..

half strength , on your watering days without any nutes. ive been intoducing gravity around week 5 until i flush. as far as getting a nitro deficiency its gonna happin to a degree in flowering, maybe a good flush and a dose of nutes will help your plants flourish
