Seedlings and feed

I keep it simple and use a one part fert. GHE Floranava. Very concentrated and all your plants will need, except for cal mag since your in cocoa.

Be sure not to go over 400 to 500 ppm to start. 400 is what I start at.

I do normal concentration from seed to harvest, and feed from day one. As long as you have sufficient runoff, you don't have to worry about buildup. That's more difficult in a large pot / small plant context. Any complete feed - macro and micro nutrients - will be an excellent option. Jack's is one, but any that work like jack's is an equivalent. Some base npk+secondary nutes, cal-nitrate and mag-sulfate. KISS principle. Get agricultural brands, not marijuana brands and you'll run into fewer problems and save tons of money.

Hello.. Hope you are well.. U shud b feeding them straight away wen in coco.. Get a decent coco-coir base grow and bloom feed.. Canna is a great range but everyone has their own preference.. They shud b fed a very light solution atm as she is still very young.. Stay safe n gud luck.. 👍🍀
