ppm conparied to EC just depends on what scale you are on. However I do agree with 1800ppm being to high. I have been seeing that plants like the lighter side of feeding, around 1.5ec. You can go higher but I think thats the most efficient. I also agree with crash about starting to lower it because they are getting to the end of there cycle. The last week if not 2 weeks should be just clean water so you can get a clean burn when you smoke.
They are 33 days into flowering, with 27 days left
They were all bagseed, I believe my HUGE Momma was one of our "good" bags. I followed the Feeding schedule on my Bottles @25ml / 4l or 2tsp / gallon, But am using liquid karma to allow more nutes to be used (unlock) Nowhere does it say to cut back on bloom if using karma, and that mix gets me up to the 1800 range. I removed some nutes and added fresh water this morning, it is now down to around 1500ppm I'll see in the morning how they are dooing, Also noticed my moisture level was about 20, Added a bucket of fresh water near the fan. What moisture level should I be keeping now anyhow with the huge buds that are growing.
She has been raised on fairly high levels her whole life and never burned once. sever others did so I did lower them, that's why I did not suspect nute burn. seems she had enough and now wants lower levels, fine by me.
just worried she is an early finisher cause she is easily 4x the size of any of the others, and they are all the same age exactly..
