she is getting deficient bro. invest in some organic nutes since you wanna go organic. but yes Cannabis always needs nutes regardless if organic or not. she's used up about all that is in the soil and will now start eating herself to survive. go to a local hydroponics store and get a veg and bloom nute solution. start at half dose the bottle recommends. you will see improvement and quicker growth. you need to spend as much time as you can on a grow. you get out what you put in. just remember that. if little effort is put in that buds will show. good luck man. if you grab some nutes you got this.
Unsure what nutrients you'll be using,but introduce them around the 2nd or 3rd week and to do at about half the manufacturer's suggested dosage. Also invest in a PH kit, soil grows do best in the 6.0-6.5 range, hydroponics and other soilless grows 5.5-6.0. If you're going to grow on a 12/12 light ing schedule from seed....it's a bit of a waste as the first 3wks. will be vegetative growth regardless of the duration of light received. A 1gal. pot should suffice for it's lifespan of going 12/12 lighting.
Unless you are using a super soil or a living soil mix; You will, unfortunately, need some nutrients to add to your water. Humboldt Nutrients has a great Organic kit you can pick up complete with some mycorrhizae and a mixing chart with a generalized (start to finish) feeding schedule; Also a PH kit will help down the road, can't express this enough as a big enough PH swing can ruin your crop or diminish yields.
@Kirr38, I actually wasn't going to use any bottled nutes', just want the real organic vibe, also don't have much spare time to watch them. Some advice would be great.
yeah I think it could probably go about another week 10 days tops. it'll start getting ugly soon though. and the longer it goes the longer it will take to recover. but as long as there is green there is life. luckily weed is very resilient. they call it weed for a reason. it's very hard to kill. had a plant with no leaves make a full comeback. so there's always hope.
also recommend switching lights to 18/6 instead of 12/12. a plant only flowers once it matures. and as of right now less light will slow that process and cause the stem to stretch out and reach for light.
looks good. been a while since I checked in but you seem to have it down. would love to see a harvest report on this if you ever get around to it. not sure if shes come down yet or not but great job.
