Oh and in hydro I just use the GH 3 part. I've had runs with and without pk boosters and to be perfectly honest, the end results were pretty much the same. I think it's probably because in dwc, all the nutrients are just so readily available in the base nutes alone.
Your FINE!
Keep going.
1-5-4 will be good, just don't increase the P.
KEEP the res temps BELOW 70F or you greatly increase the chance of root problems!
Thanks again guys I turned that space heater on low last night during my lights off time she grew another inch over night. Here she is today I can see only one yellow spot on one leaf but its from the light I think
