yeah that does help ,

i'll save some time n just measure the ingoing feed/water, still need to get a ph meter tho.
correctamondo, there are 7 plants, the CFL is for vegging, i plan on using a 600w HPS for flowering... will that work or do i still need more light for vegging?
i thought over watering was hard to do in coco, but nice one i'll keep an eye out for signs... I was just trying to flush the system from the nute burn hence the frequency.
