Just wanted to ask how the ph swings are going? If you still have the slime try h202,just dont use the 3% stuff. 30%-50% is best,dont forget to wear gloves and glasses when you handle this stuff it will burn your skin and will blind you if it gets in your eyes. If you cant get it, I have a friend who used to freeze ph'ed water in cups and add them like big ice cubes as his add back water.
There is no 1 most important thing when growing,its all the parts as a whole that make the perfect enviorment. But I did want to stress the imporance of ph. A stable ph causes less stress so always go with the biggest rez possable(whinin reason..lol) it will stay more stable. Also ph problems can look like so many different things,but if you know your ph is right on,it makes diognosis of problems alot easier. ph is so often over looked by newer growers I just wanted to stress the importance of it to you. I hope you have a great grow!!!!
