Summer Grow White Widow and others

[MRDiff]

So back in May I started up 2 Seedsman Fem White Widow, 2 Female Bubblegummer, and 1 DNA Genetics Lemon Skunk. The plan was to flower 5 plants in a cabinet with my 400 HPS. Unfortunately, I soon realized I wouldnt be able to flower them all in my limited space. So I currently have to grow areas.
The cabinet has the 400 HPS and 3 plants, 2 White Widow and the Lemon Skunk. In a closet, I put the too BG plants under about 11 CFL bulbs from a previous grow. All plants are between 2 and 3 feet right now and are on day 14 of flowering.
Over the past 3 weeks, I have given them nutes only once. At one time they had nute burn so I didnt want to continue to feed. But even with me back off the nutrients, the plants still have yellow tips on the new growth (primarily in the HPS cab). Should I continue to lay off the nutrients? I am currently using 2 teaspoons per gallon of Fox Farm Tiger Bloom ph'd to 6.5. Soil is FFOF, they are all in 3 gallon pots.
Any suggestions or ideas to help my grow is appreciated. I also considered that the tips may be affected my the heat in the 400HPS cab. The bulb is 18 inches from the tallest plant.

First pic is Lemon Skunk which has "the claw" pretty bad.
Last 2 pics are the CFL grow.

Using FFOF soil and FF nutes, don't feed them for a few weeks. There are plenty of nutrients in the soil already. I found that out using Grow Big even at half strength and less experimenting. Flush them really good and then use Big Bloom every other watering. Worked for me. Better luck with the next go around. :thumbsup:
