Hello everyone! I have got my first grow on the go 4 midnight express and one purple kush I think from a friend. Make shift tent I made haha with tin foil etc. Light is a hps with digital ballast that has been on 400w but up to 600 now and plant aaround 24inch from light. I have 230v fan with carbon filter but not directly at plantsz. I did not want to use nutes as I wanted a natural no chemical grow and all that bla bla. started germinating on the 27th April. All autos. The picture are from this morning so the boys have only been awake about an hour. I had one slightly yellow leaf that may have been from being to close to the light about 8days but it doesn’t seem to have spread. I water about .5l a day atm but depends on how heavy my pot is and how dry etc But any thoughts / reccomendations is appreciated me know. Peace.
