I remember being freaked about everything too... weve all gone through it. Remember the term "weed" is not slang! This plant was a weed for millenia before people started ph checking its soil with a goal down to the tenths and adjusting if its a tenth off with urgency, adding 64 different additives to make ensure its survival, making sure her flower lights are not on for 12 hours thirty seconds... yes we can extenuate already existing genetic traits of this weed. She is no pussy! This is a tough veracous weed that wants to grow...
Folks scare new folks at times making them think this is extremely difficult to get right. Remember the plant is the captain, you are merely her assistant...
