Is that the veg formula that you fed? Sounds like a flower cycle feeding mix.

The cots are a nutrient reserve for the plant. It's nature's way of ensuring the seedling off to a good start in life. Once a root system is established the plant will canabalize them. Also with the first true leaves, single bladed.
Don't worry-
Im using this ghe feed chart i bought everything from the feed chart + vodoo juice

Aint soon for the plant ti "canabilze" them? Onlus 5days old, the root today started to touch the water

Voodoo juice, as in Advanced nutrients? Microbials have no place in DWC! Unless they're specifically to clean roots and rid nasties that create biofilms. Those microbes are best suited for coco, Rockwood and soiless organic substrates.
Along 2 dwc plants im doing other 5 plant in cocco, but i read on this forum that some people used vodoo juice to prevent root rot

If they're fading, then the plant is using them. Factoring in that all other parameters are in check. You have a vigorous seedling. They require more everything.

I bought into the AN line of bullshit 12 years ago. I bought the entire line of pH perfect and additives. $400 if I recall. Not worth it.

All you need for DWC is base nutes
Just bought them so ima ho with them for now would be great if you have a Better feeding schedule/advice for using them

Well for any bottled nutrient for hydroponics I'd go half strength of what ever dosage they're recommending for that particular stage of growth. You can always add more if the plants can tolerate it. But by adding too much you create a higher EC in the water than what the plant has internally. This will pull nutrients out of the plant and lead to lockout. Less is more with hydroponics.

Avoid any additives that contain kelp extract and microbials. Those are best used with a medium that can harbor their growth in the rootzone. Any silicate can be used in conjunction with veg/flower base nutrients, PK bloom boosters and bacterial root protection products. Avoid any and all organic derived. If you want microbes look into a foliar spray products, ie: EM1, Photosynthesis Plus.
