What's going on ROLLITUP! 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. Here are weekly pics of my babies,
