Oh I'm sorry I posted another forum for week two and one. My grow medium is rock wool and Clayton pellets , I have 120 watt led light using general hydroponics trio nutrients ( micro-series) and my light cycle is currently 18/6. I am growing in a six foot tent in my closet, the grow from germination to now started august 24 the, am growing pineapple express, purple kush, auto cheese and white widow. They all seem to be maintaining a great pH ( between 5.8 and 6.2) the humidity is between 48 and 61 percent and the temp stays between 74-81 degrees f. I installed a recirculating water pump with my bubble to help aerate as well as manage the pH and it seems to be doing well. I have questions about the TDS and the nutes, because I was told they need to be maintained around 500ppm to start and gradually go up , not to exceed 1500 ppm, now is that for autos or just regular grows? Any feedback and help is always welcome. Thank you in advance and happy growing.
