I have a 16 gallon top-fed DWC running General Hydroponics Flora trio, CaliMagic, Hydroguard and Liqiud Koolbloom. +|- 950 PPM
600w MH for veg (but usually dimmed to 300 because of being out of town), and 600w HPS for flower. This pic was taken at Day 14 of flower (HPS color tweaked out in photoshop)
QUESTION: When I was in veg I would buffer PH to around 5.6-5.6 at res changes then let it gradually drift upwards towards 6.0-6.2. Now that I have made the switch to 12/12 and 75% of the reccomended GH nutes for transition (roughly 1:1:1 Micro, Grow, Bloom) the PH has been sitting right at 6.0 for 10+ days now. Is this ok, or should I buffer for a little drift? I also much of my new growth is lighter lime green and not darkening with time. Is the light colored new growth related to this lack of PH drift or some other factor such as my running only 50% of the suggested Calimagic.
Thanks for your answers. Overall it was a great first DWC veg, now I'm just trying to stay on top of things and have a good flower.
