20-20-20 is a good start, give them a small dose at first and as they get bigger give them a bit more until they're getting a full 1 and half tablespoons...

Storing Coco Coir
I have some leftover coco coir, and I mixed it up with some organic time release dry fertilizer. Can I store this and use it again in a few months? If yes, will I have to add in more nutrients next time?

tank feed
How long can I keep a mix in this tank. I must admit it does not smell good. The mixture smells so bad after a day or two and does it affect the plants in any way?

Flushing
I fed nutrients instead of water flush to a plant in week 8 of flowering, the plant itself is ready to harvest. Should I wait a week to flush or will it be ok to harvest and dry as I do not want to wait much long it as the plant is in the perfect sweet spot to harvest.

EC and PH of Runoff still Higher than Solution even after a flush and lowering the EC
Hi, i still having this problem even after down the concentration of solution for 1/4 that scheduling feeding table says. I have some measurements listed in the week 10. Maybe my media is buffering PH and EC because i used to recycle it over times?

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?

When to introduce nutrients to coco / perlite and how to water seedling?
Hi!! I am doing my first ever grow. When should I introduce nutrients to my plants in coco? They have just sprouted and I was only giving them some water with H2O2 at a PH of 6.2. For a seedling, do I need to water until I get runoff? Thank you!
