    Hello all I'm a little unsure of when to change up.nutes. Sensi Grow Advance Nutrients to Sensi Bloom?? I fed yesterday the Grow & im wanting to flip em without any fuss. I did a little defoliation also. I've read it's ok to flip now but others say to wait. Keep in mind a lot of these posts are from mid 2000's so I'm sure things have changed a bit. Thanks in advance.

    Give it 3 or 4 days as long as they are happy your fine.

    Id switch to blomm after the first week or so of flip then switch to bloom.

    But i have switched to bloom at the same time as flip and it didnt hurt anything :)

    I would wait until stretch is over. Even then I don't like bloom boosters.

    You would be better off with a balanced feed.

    I wait till stretch is done or about 3 weeks after flip.. It's bloom food why use it before they bloom...

    Well i always figured if week 4 was when you where supposed to max out everything then taper off from there .

    So id start on a bloom mix a week after flip so i could gradually increase ppm till week 4 ish.

    Now i use a salt based nutrient and will basically just back off on the cal nitrate at week3-4 and increase the base or add a pinch of mpk.

    But i try to adhear to a less is more approach .
    I start cringing if i take them near 1000ppm lol

    I switched them to 12/12 last night. I hope the little defoliation I did (. I chopped the bottom branches)will not slow it up too much? They're like 17-21 inches before flip. Mostly Indica so I doubt they'll stretch too much. Thanks to everyone who commented. PS I'll be Bach with more questions. I like all the options

    Yest Advance Nutrient calculator suggests to start Big Bud at week #2. I used it as a guide line. I've actually got nute burn on the lower leaves & some yellowing here n there. Im a little worried though. They are bushy but not many branches.

    I don't switch, I run Maxibloom from start to finish.

    Advanced nutes runs high ppms if you follow the driections on the bottle at least mine did.

    At 2ml per liter i was at like 800 ppm and i dont like it when i start going over 1000

    I add more Bloom and a half dose of Big Bud a week before flipping to "prime the pump". They get the other half at the flip.

    I've tried side-by-side with plants waiting two weeks before adding BB and the early ones did much better. Plants eat up to 4X the nutes during the stretch and set their bud sites so I figure they need a good load going into stretch to do their best. I got a free 500ml bottle of Bud Factor X that I will be using in comparison to see if it does anything noticeable. May be a decent supplement according to a few guys I know that swear by it.

    Rhino Skin is the only other AN supplement I use and I start the plants on low doses of it when they are still small.

    Good luck!

    A&B for veg 1st 2 weeks/stretch, A&B for bloom until the last week here. My thinking is the majority of growth in that first two weeks while they begin setting bud is vegetative growth.

    Bloom to me is the Bloom part of a 3-part nute regime. I boost that part just before flipping to flower.

    Pretty much grade school stuff I would think even the newest nOOb would know that.

    The secret is like with every other nute maker is to ignore their nute calculators. Just designed to make them money.

    I start my DWC clones at 300 ppm which is about 1ml/L of each 3-part. As they begin to get roots going and grow up top I add nutes to boost the ppm and keep doing that as they grow and can handle higher PPMs. I may change nutes after stretch but many times do the whole grow without ever changing nutes other than drawing out nutes near the end to lower ppm.

    I've only done 50 or so DWC grows with AN nutes since '01 so may be lacking experience but I don't think so.

    As Trump would say, 99.9% of AN haters have never used AN nutes. SAD! ;)

    Not quite i used it for over 5-7 years.

    I just finally decided the "ph perfect" aint perfect enough for me anymore.

    I dont hate them i grew out of them ;)

    Besides the fact that my roots dont get stained from them anymore is worth it to me. :)

    I havent had pure white roots the whole time I've used advanced lol
