I have 5 clones in an ebb and flow system they are about 3 weeks old and im using the Lucas formula. I am using a 400 watt mh for veg. My ppm is 446 I started nutes 2 and half weeks ago so ive been slowly ramping it up to where its at now. Most of the plants have yellow tips on them but one of the trainwreck clones has gotten quite a bit of yellow on it...any advice..Am I under feeding them. magnesium def ?..Oh and my ph has been steady at 5.7. They are fed 5 times a day..Any advice would be a huge help
