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.

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

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.

How much hydro nutrients per plant?My two tiny plants have access to 100 liters of water with nutrients added according to the schedule of the producer (Hesi). But the ratio of water to plants is very different comparing to smaller scaled hydroponics. Is there a rule of thumb or such?3 years ago

Substitute for liquid hydroponic nutrient solutionsThose solutions (like Hesi Hydro Growth) seem to be ridiculously overpriced, like 10€ for 1 liter fertilizer solution which consists of mostly water itself is a total ripoff in my understanding.
Is there a substitute for those heavily overpriced nutrient solutions?3 years ago

Co2/Temps/NutrientsI pushed the temps up and got the VDP on point w/co2.
Now since the plant is drawing a lot more water up through the roots, I've noticed very slight nute burn on the newest leaf growths.
Do you have to drop PPM's as temps rise? I thought it was the other way around?

Am I watering too quickly?Someone suggested that I use this pump to remove excess water from my tray. It wasn't powerfull enough for that, but it works perfectly (I think) for slowly(ish) pushing a good bit of water to the plants. Is this too fast? Is it too slow? Does it really friggen matter?
