Just to be sure we are both on the same page, when you program your lights through ecosmart, you click on each reference point. You have the ability to set a % for each color channel (blues, uv, violet, whites, green, red, etc...). You then have the ability to set the intensity for those color channels. After you save it, the graph will show an overall intensity % for that light point based on the % for each color channel and intensity % you selected.
Changing the white channels by 3% should be fine. Changing the INTENSITY for the light point by 3% might be too much. You want to keep the OVERALL light intensity changes very minimal. To give an example, say you are running your blues, uv, violet at 100%, whites, green, and reds at 15% and at a 25% intensity. Your overall intensity for that light point will show as 16% on ecosmart. You would not want that overall value to change that much. A change from 16% to 20% for instance is not just a 4% increase...it would represent a 25% overall increase in light intensity (4 / 16 = 25%)! So just be sure any changes you do are truly small changes.
I think earlier in this thread, several of us had advocated turning your lights down slightly, but you wound up turning them down significantly. You may have meant to do that, but your overall light schedule before did not seem that far out of line based on the par values you shared. LPS are not going to need a lot of light
