Healthy plants yellow leaves???

Just went into flower three days ago with feminized snow white and things are going well except all of new leaves spouting on one plant are yellow, some all yellow and some on the middle of the leaf going out.


My nutes have been low, around 550-700 ppm this past week. Could this be the problem? Also my temps are about 69 daytime and 67 dark ( i have a 400 watt hps light approx 6 inches from my plants.


Any advice is appreciated!

1st check your PH (6,2) and it looks like you could use a little more nitrogen.What are you feeding them?

in my opinion you need some more nutes

Put a little pot ash on each plant this should help with the nitrogen issue but all this could be the light change try and get your ph around 5.5.I never take any of my plants above 5.5 after watching the greenhouse dvds i used to but i always had a few problems.This is hard because we don't know what feed you are useing.Also do you flush your plant you may have a excess build up of unwanted salts flush them a few yimes during a grow.

start of an MG deficiency, almost 99% sure.

1/2 tsp Epsom Salts per gallon of water
