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.

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.

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.Feeding. Other

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 youFeeding. Other

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

We have decalcification machine. Should I add Calmag right from the start? How much? (Autoflower in mostly Biobizz Allmix)We have a decalcification machine (natrium based), so I have low magnesium/calcium. People say my soil is low in cal/mag. Should I add Biobizz Calmag on my first watering?(50% of recommendation for autos?) This one looks already droopy, doesn't it? Think I need to water soon.Feeding. Other
