I did the flush and checked the ph which was what I thought it was pretty close to right on at 6.5 but since the flush and then a foliar feed after they have just been doing great I wish I had my camera because they are doing amazing now in the last 3 days I have had to raise the lights twice they have shot up from 8.5" to over a foot tall actually now they're about 13.5" and not stretching or getting lengthy at all so I am very happy for my first grow and thanks to all for the help so far.
