Hello my romulan next generation plants are in their second day of flowering. The PH of my soil is 6, and I am using a 1000 watt HPS bulb. There are currently 10 plants which started from seeds. They are in 2 gallon pots. The light is currently 3 feet above my plants which I lowered from its previous veg height of 4 feet. I had some problems at the beginning of my grow with a late transplant but all of the plants seem to have recovered except for one. I am using sensi nutrients which I will post pictures of. Some of my leaves have brown spots as I will post while a few others curl downward and inward. The only ventilation i have is an ingoing fan and a hole on the other side of the shed. My shed is outdoors so temperature control is a problem, I bought a heater for the times when the light is off. I am curious what a good temperature to keep my plants at and also what is a good PH as I have been told a few different answers about the temperature. Hope you enjoy the pics.
