leves going yellow........ fast

Alright, I know that plants will drop their leaves in the flowering phase but, they seem to be turning wrather fast... like the bottom 1/3 of the leaves.

Im using sunshine pro mix for soil
open sesame, beastie bloomz, cha-ching (fox-farm bloom 3 stage)
1000w hps and 400w hps 12 trees

Is this perfectly normal and Im just paranoid or am I missing some nutes???

ps the color of the leaves is a very pale yellow.... no curling, no stunting, no deformed growth, just hella yellow leaves..

thanks in advance to all opinions or facts

throw it some nitrogen. one good shot or a few little doses. don't over do it or your buds will stretch. they still need a little nitrogen during flowering, some more than others. i'd go 1/4 - 1/2 strength of veg then wait 2 days. you will be amazed when all the leaves turn back to green.

one more question... I just watered and fed my nutes, how should I apply the nitrogen?? It usually takes 6 days for me to water again...

Yep N will help early in flowering.

but how should I apply if I just watered, just use like a litre of water w/ nitrogen?

you don't want to burn your roots. uuuuuuuuuuuhhhhh. thinking. thinking. they are going to yellow even more over 6 days. uuuuuuuuuuuuuumm. thinking. thinking. i don't know. is there a foilar feed? is that an option?

time for a new thread lol
