I'm currently on my second grow using the new CS formulation. So far I'm very pleased with the results.
My first grow was Blue Dream, which I had previously run using the House & Garden lineup. I did run into some issues on the first grow and got into a situation where the plants weren't feeding well and the pH was fluctuating on a daily basis. After trying to rectify the situation myself to no avail I finally called CS tech support to get their input. The only thing they could come up with was the silica I was adding. I found with H&G if I didn't add silica my stems were weak, to the point that you could compress them easily with a gentle pinch. CS said that silica wasn't needed with their nutes. I was skeptical since they do not include silica in their formula. I stopped using it on that grow and haven't used silica on my second grow. Have to say, in spite of my reservations they were apparently correct. This grow I'm not having any of the issues I had with the first one. My pH is stable and slowly rising as my ppm drops.
Trich coverage with the CS nutes was significantly improved over the H&G, as well as potency. The buds were noticeably bigger and over all yield was higher by about 4 oz., or about 1/2 oz. per plant. I'm also ran at slightly lower ppm. With the H&G I run the BD at 450 ppm at the height of feeding. With the CS I never got over 375.
My current grow is OG Kush that is just finishing stretch. So far it's the best grow I've had yet. I've not had any issues. The plants are feeding well and the pH has been consistent with no fluctuations. CS will be my nutes of choice from here on out.
Thanks again to UCMENOW for supplying the samples.
