Well were in our first day of week 5 flowering today, and ive noticed that over the last couple of weeks the PH has been climbing faster than ever.
Yep.. I woke up one day to find some nute burn... i mean it still might be a little as were running 75% even though i dont think they like it very much, but it wasnt, it was the PH, the whole tank had gone up from about 5.8 to at least 6.5 in a day. Keep a close watch on this, i dont know how many other people have problems with PH but i check it every day now without fail
