Hello. In the back of my Advanced Nutrient catalogue it has charts that are up to 2000 ppm. I usually do 800 to 1000 ppm in veg and 1200 to 1400 ppm in flowering. At 1600 I usually get some leaf tip burning and huge buds.. Chuck.

expert opinion asked ? Maturity in day 49 flower from 60-65 (according to breeder)
Maturity in day 49 flower from 60-65 (according to breeder) I'm not sure about the degree of ripeness. I used Co2 for a few weeks (1000ppm), the grower says ~60-70 days of flowering, so I would be missing 10-20 days, but they look quite ripe ? What should I do Thank you

Feeding right after repotting (coco coir).
After repotting an auto flowering plant I get runoff EC of 800, while feeding water has EC 1200. I guess EC gets diluted (biggest part of coco coir is new). Should I increase EC of the feeding water? I see slower growth but it may as well be due to stress of repotting.

Questions about watering
I created a 40 ml solution, the instructions say to transplant after the sprout has grown to the top of the plastic cover and the roots are visible through the plug. The question is, is 40 ml of liquid enough for this growth? I think not.

Nutrients or am I wasting potential.
Hi. Is there anyone that could maybe teach me a more productive or more beneficial way of getting the plant to intake the nutrients. The way I'm doing it at this point is just mixing it with water.

Flushing Autos
I’ve heard arguments for flushing from every 4th feed to once every 4 weeks or some growers don’t flush at all until the end right before harvest . I should note this relates to coco grow medium .
