What's going on GrassCity! Just wanted to post a few pics of my current grow. I am currently running a 2x4x5.5 grow tent with a 600 watt HPS in a Yield Master II air cooled hood. I am growing hydroponics DWC. The nutrients I chose are Advanced Nutrients PH perfect 3 part, along with Nirvana, Big Bud, B-52, Overdrive, Rhino Skin. Right now my ladies are in their first week of flowering. The strains I chose to go with are 3 x Girl Scout Cookies and 3 x Purple Gorilla. So far so good with the current grow. Using the PH perfect line had me kind of worried at first because when all nutrients were mixed, I was still getting a reading of 6.0 - 6.2, that's just with the 3 part. I noticed when I started adding the additional nutes, it was gradually dropping closer to the 5.8-5.9, but that's only if I mix the additional nutes, without them the ph still hangs around the 6.0-6.2 range. No biggie, I went on with what the rep's told me, and that was to NOT use ph down at all, just let the nutes do their job. I change the res every week with new fluids. I started using 1/4 strength in the beginning and gradually moved up to 3/4 strength. One week during vegging, I did try full strength and noticed terrible results. Lots of nute burn and yellowing of the leaves. I quickly flushed 3 times and changed to 1/2 strength. These nutrients are pretty concentrated, but they work great if used less then the given dosage. Right now my ladies are in their 34th day of flowering. Attached are older pics taken in sequence while they were growing. Front three are Girl Scout Cookies and the back three are Purple Gorilla's Veg'd for almost three weeks before I switched to a 12/12 cycle.
