When do you guys start your actual nutrient feed t...

Once my seedling have popped and been potted into there container, i tend to give just ph balanced water for the first week then introduce nutrients into the mix from week 2. A lot of growers would recommend using half of what the stated dosage is for the first feed then building up over time to make the requirement for the plant. Every plant/nutrient brand will say different things but your in the right place for some of the bests advice :)

Well you can start light feeding if you use ro water you can start feeding like one or two mills of grow and micro and beneficial bacteria and a root Stimulator and if you using RO water you need cal mag and yeah feed early I’m always feed from day one ☝️ just saying don’t get crazy with it .

@motaman311 has said everything, follow his recommendations. I would just suggest beneficial bacteria’s in the first week, mychorizae, trichodermas, Humic and Fulvic acids.

Hi @mastermind74! Considering you're growing soilless, you must prepare your medium with a few nutrients before dropping the seeds. Indeed, coco has nothing to offer to the roots, that's why we usually add humic acid, root stimulator, and/or a small dose of Nitrogen, in order to feed the seedling for its first days. I usually start with half of the recommended doses, even with organic nutrients, seedlings can be sensitive so that's a tricky game: not enough nutrients in your coco and the seedling will suffer from deficiencies very quickly, too much nutrients in your coco and the seedling will burn very quickly. By the way, I love your controller, would you please show us some pictures of the fans and eventually a video of the full setup in action? Let me know in the comments section if you need any further information, and happy growing! 👊

In a soilless medium there are no nutrients. It's up to u to provide nutrients from seed to harvest. Now say you had soil this contains enough nutrients for seedlings in the first two weeks. Now for strength I would start at 1/4 then slowly rise to 1/2 over a 3 week period. Any only go further if you see signs she needs it but 3/4 max. Good range for ppm if you have a meter is 400-1000 max

As a hydro grower, I start nutrients at about day 7-10 of life, depending on how she looks. If the cotyledons start to go yellow before much else is growing, add nutrients sooner... the purpose of the cotyledons is to provide food for the early stage of life. Then I add around 200-250 PPMs (30% Strength) and then slowly increase as she grows. Less is more when it comes to growing as I am sure you've heard before. happy growing! 👊
