So here it goes. Water temp 70 degrees F. Ph 5.8 1/2 str nutes. yellowing of older leaves was from my ph ordeal. Had to leave em at a relatives house for a week and the ph dropped to around 4. New growth looks good. I hope the tips of my leaves are brown due to my ph issue. All in all they are starting to grow really fast now. I have to start flowering them here soon in the next few weeks so I hope I can keep the ph in check so they can grow bigger. I added a fan in there as well and holy shit does that make a difference in growth! When I start to flower them I will be using 4 68w soft white cfls. Trying to harvest around june or else im fucked! wish me luck!
