The pH is good, the bottles says 3 tsp per gallon and I put one tsp in a gallon and put it on the plants... I burned them when they were babies about 2 months ago and when I flushed them they came back and I swore off the nutes until they were big and strong. They are big now ( about 2 feet ) and I thought it time to do it again and I watched them every hour and when the tips turned brown a bit (@4 hours later) I flushed the shit out of them. It hasn't gotten any worse so I think they will be ok but I have to understand this better. When I switch to the clones that I will grow soon I will be using the ebb n flow setup with the hydroton pellets and I hope this problem won't be as tricky. Well I appreciate the support and wish this project didn't have to be so hush hush. Thanks again, I would post some pics but all I have is this phone and it won't let me post from it. When I get the computer going I will for sure.
