Big bud fast version. Crop king seeds

This is my first grow. Im starting out with a 2x2x4 with a intake of 100 cfm exhaust just an clipon fan for a desk. Ipower 150 watt led with builtin setting for full/veg/bloom as well as time setting. Shitty part is it doesnt reset when there is a grid outage. I suppose its alright it rarely happens. 3 gal pops with fox farms ocean forest soil. Im checking moisture in the soil light stregth and ph of the soil regular. Water is tap. But with a Pur filters, if you do your research its a great filter and it also does filter chlrine and flouride. When i do water i do have to lower ph not by much.
