When to start feeding autos

some of my first grows ever were 50/50 maybe 60/40 OF/perlite, respectively. I'm referencing one of my last grows in it, fwiw. 10 is probably too early. 14 may be borderline, but both would take a bit for the ramifications to show later on. can easily react before it is a negative impact. Reviewed notes. Harvested back in november. i started nutes after 1 week and by day 21 i needed to take a week off. I fed and took another week off... then fairly consistent after that at 1/4 nutes. So, day 21 may be smarter and easy does it.

With the ocean forest in there fam ull be set for 3 weeks for base. I would definitely start off feeding ur base than! I'd get some cal mag into her at that point for sure too! Prior to that u should have all u really need. Mabey some root booster,microbes, enzymes, and certain supplements would be good before week 3... but not needed.

I think the convention is to feed weekly, unless there's a reason not too. I've grown in fertilized soil with almost no nutes and this grow I'm using a pretty complete feeding program. You're going to get a lot of opinions on this. My opinion is nothing when growing in soil until day 7, then give it a touch of potassium silica to harden against fungus. I also use a soil conditioner on day 7 that has no real NPK value: it feeds the microbes. On day 14, some soil growers will introduce their plants to a taste of grow nutrients at 1/4 strength; others will wait until day 21. I do it on day 14. Day 21 its pretty much universally accepted to feed autos half strength grow nutes. You rarely go over half strength with autos, though some are hungrier than other strains. Between day 21 and day 28 pre-flowers appear on most strains and this is where opinions differ. Some growers and almost every seed bank and nute company will recommend bloom nutes by day 28 at the latest, but other growers still feed veg or something in between. After that, there's not much divergence anymore: bloom nutes at half strength in day 35, tapering to half the week before flush, then none for a week or two. Some add a bloom finisher in the last week or two before flush. The big thing with nutes is less is more: easier to correct a minor deficiency than deal with nute burn and lockout.

Yeah OF is 3-4 weeks or a month. If you cover you soil you can water less and stretch it out more. Using teas and foiler sprays will enhance the microbial life within the soil and give you better plants...feed your soil man.

Ocean Forest has enough nutes for 3-4 weeks normally. So maybe around week 2-3 with your mix. Hopefully this helps! Happy Growing! 👊
