    Default Feeding Autos vs. Photos

    When growing Autos, do folks still have a Veg nutes schedule and a Flower nutes schedule?
    I'm assuming you cut down on the Nitrogen once flowers begin to show?

    I would imagine it depends if you're using soil or coco. I do autos in soil, don't really use grow nutes as the soil usually has enough until flower, but I do use bloom nutes.

    In my garden I don't treat the two very differently. I switch to bloom nutes (or add PK to the base in my case) about 2 weeks after the flip. With autos, I just read the plant's growth. Plants finish getting taller at around 21-24 days post flip, or so says the research. So I like having some extra PK in the res when they start showing preflowers. Used to switch to bloom nutes at day 21 or so. Both timings yielded jars.

    With autos, the timing disregards the "flip" obviously and I just go on the growth rate.

    If I had to approach a tent and had no idea when it was flipped, or if it was an auto tent, I would just watch for the stretch to stall and switch it up.

    Also, remember that we've seen awesome grows with just base nutrients. Canna A/B and MegaCrop are 2 lines that I can comfortably say from experience don't NEED a booster.

    Cheers

    I just start feeding veg nutes after 2 wks, lightly. Probably have a few veg feeds into week 5 then I switch to flower nutes. You'll find your veg nute lasts 2-3 times longer than bloom nutes

    I feed any autoflower strain at 50% the dosage I gave to photoperiods. Shorter grow period so less time for plants to overcome PH issues, overfeeds, overwater or any mistake a person could make.

    Less flushes, less salt also.

    I totally disagree. It depends on the genetics and particular strain. Give some autos full strength ( recommended by manufacturer) will result in deficiencies, lockouts and ugly leaves. Some strains love full strength but many do not.

    If a plant is big and ugly, I'm not impressed.

    Using FF Dirty Dozen, also FF Wholly Mackerel and Kelp Me Kelp You at the moment. Finally had used up my B.A.S. organic line, took 2 years. I got tired of constant battling fungus gnats, and had smaller yields with organics

    I think following recommended dose by manufacturers is just stupid, I suppose your best friend is ec/ppm meter then you know exactly what is full dose or half a dose.

    Quick example : I'm using with V8 in my mentoring grow greenbuzz nutrients, we check calmag for ppm/EC if I would follow recommended dose 2ml/L my ppm would be 70 does it mean that's full dose? To make it to ppm 300 I ended up adding 25ml/2L which according to manufacturer would be 12x more to their recommendations
