I recently switched to ro water and what i do is 5ml of cal mag for every gallon i make of water or feed. Ro water has almost no calcium or magnesium in it so always add. Its super hard to go overboard with that stuff. Just add all your nutes and cal mag in then ph the water and your good to go.

Questions about wateringI 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.

Help: potential over fertilisation or over waterningI used Biobizz bio grow, 2ml/L and sprayed them more than usual. The tip of the leaves is getting yellow. 2 plants have the leaves pointing down and seem more textured and tick. The other 2 (the biggest) seem better, but the yellowing of the leaves is more evident.

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.Setup. Strain - Autoflowering

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
