This thread really helped me out. I'm using a homemade drip hydroponic bucket system with a 3 1/2 Gall res. 1st grow. Temp is 65F night - 70F day. Humidity 40-60% I use the 3 part flora nuts by GH with the formula on given on the bottle. 600 watt HPS in a cool tube. I am uncertain of the strand that I have. (eekkk! I know) My girl is in he 4th week of flowering. Being my first time, I had a few minor accidents. For example, the 2nd-3rd week of the flower stage really caught me off guard. My girl shot up so fast that in one night she grew a retarded amount in length and ended up touching my cool tube which turned a few leaves a crispy color. But she actually has recovered just fine. I've noticed that the flower on that particular shoot is still getting bigger. I refill my res with 100% strength nuts daily and usually set my pH at 7.0 because of other obligations throughout the day. By the next morning, she has consumed 1 gal of solution and my pH has fallen to 5.0 or below. (Is that normal?) The size of my buds are pretty small, about the size of a 20oz soda cap and slightly bigger in the canopy. All of my leaves are a good green color and no signs of curling. (my fan leaves are fucking huge) I just starting using Big Buds at the beginning of the flower phase she's in (week 4) and I'll be using Overdrive here in a few weeks. I was seriously scared my flowers where stunted but this forum gave me hope. I do have a question... she has roots growing from the stem just above my grow rocks. Fucking huge ones.. Is it a problem that light is getting to these roots? Her 12 hours of darkness is un interrupted.
