Does giving an auto bloom nutes stop all vertical growth?

Hey guys,

I have an auto that i am only giving veg nutes too right now and its is 38cm high. I think it is due for the bloom nutes and i am wondering if when i start giving bloom nutes will the plant get any taller, similar to a photoperiod plant that still grows vertical after the lights are switched?

I don't want to stop her vertical growth much as i have read that leaving it a little longer on only veg nutes it will end up as big as possible. My first time on an auto so not sure.

Auto's grow and bloom regardless of light cycle. Depriving your plants of nutrients won't stop it from stretching.

When the pistils (white hairs) burst out of the bud sites you are in transition and you should taper then stop bloom nutes. Just read the plant.

To stop vertical growth you need to use super cropping methods which basically means to pinch, twist, weaken and sometimes physically bend over the top shoots. I suggest spending some time on YouTube to learn what's what. It's canopy management to ensure light penetration that ensures we aren't wasting energy growing buds that are receiving hardly any light.

Quick overview giving just one type of a plant as an example. (Works the same no matter how many tops)
Say you have a plant with two tops but one top is larger. In this case you can pinch, twist and weaken the stem of the bigger shoot but don't bend. While it repairs it's stem the other shoot(s) will catch up. Second scenario you have a plant with two tops both the same size but they are growing to tall/big in comparison to the rest of the shoots. This time you pinch, twist, weaken and then bend the top down just below the level of other shoots. Those tops aren't dominant anymore and the side shoots will fatten up, the rest of the plant will catch up some as well.

Not true.

Things like higher amounts of nitrogen can lengthen grow time. Switching to bloom nutes early can slow upward growth.

There are several tricks to growing bigger autos.

Yeah it is true excess Nitrogen delays flower and hurts yield through inability to grow roots freely. That's easy to forget if you are of the school less is more.

Yeah i am following advice of an article i read on here I'm sure it said if you give bloom nutes it stops vertical growth and that a lot of auto growers without experience start bloom too soon and don't give it the extra week in veg . I was under the impression that i need to measure the height everyday and when the height plateaus thats when its finished its vertical growth and then it would be onto bloom. Should i stick to this advice?

Wrong. You are talking over dosing with N.

I said higher amounts of N.

These are 15 inch pots the size of a five gallon bucket.

nice plants bro! They look really good. It will be strange having only one cola after the photoperiod lemon skunk i have got FIM'd and has about 5 colas!

Research photomorphism, your spectrum and light cycles have a use.

This plant was fed "veg nutes" through her whole life and clearly had trouble establishing roots...

I don't buy into the veg/ bloom nutes.

A person is better off with a balanced fees the whole way through.

To answer your question OP environment plays a bigger role in the morphism of your plant than nutrients

@whitebb2727 ya I'm using foliage pro all the way through, I do add potassium sulfate during the bulking phase. I don't believe the phosphate hype.

I ordered the sample from dynagro. It included protekt and mag pro. The mag pro will balance the foilage pro out.

Yes, tricks but not depriving your plant. What you're saying is very different from simply not giving your plant nutrients.

I think protekt has a use,the added potassium will promote bulking, but honestly I think there are better forms of potassium to use. mag pro is just Epsom salts with some phosphate added and really isn't that useful, I'd rather just apply Epsom salt personally. But to each his own.

No one said anything about depriving nutes. The op was asking when to switch to bloom nutes.

The op would be better off sticking with veg nutes all the way through.

The whole PK booster for flower is a myth. A balanced feed is better.

Maybe it's not the mag pro. It came with a small bottle that balances the foilage pro to even npk.

The protekt is good for weight and drought resistance.

It is dynagro bloom. 3-12-6. It will balance the foilage pro out. The foilage pro is fine by itself.

I paid $19 for a quart of foilage pro, quart of protekt, pint of bloom, and pint of rooting solution.

The mag pro came from another company.

For documentation reasons I will do a grow with rxgreensolutions. They sent me a big sample pack for free.
Quart each of grow a and b, bloom a and b, micorzzea powder and some other stuff.

Well you have to wonder if foliage pro needed an even npk, they could have made it even in one bottle.

Mag pro is nothing but an unneeded P booster with added mag sulfate IMHO.

Ya protekt is good for weight because of the added potassium, I don't worry much about drought resistance as I grow indoors in a controlled environment, but I can see how some could use that. Personally I prefer potash for the added sulfur and potassium over potassium hydroxide. But I grow for oil so I suppose my needs are different.

The foilage pro is for tropical plants. They also make another feed that's more balanced. I just ordered the sample pack. I needed protekt for my guerilla grow. The silica adds weight to.

I just looked. It is dynagro mag pro. It is 2-15-4. I don't use it.

The dynagro bloom has a whole lot of micros in it.

I don't really grow synthetic. I got these samples to do a couple grows for documentation reasons.

Ya the dyna bloom has micros, but so does foliage pro, both are complete as far as micros go.

The foliage pro is for tropical plants because dyna gro doesn't want to say it's for cannabis... They didn't just come up with 3-1-2 for growing mangos and pineapples.

I don't know about silica adding weight itself, somehow I doubt that. And if it does its fiberous weight and probably not the important kind of weight.. Does it make stronger more drought resistant plants, most likely . There is no doubt in my mind about the abilities of potash for oil and actual bud weight production.

Im not intending to argue with you here,but dyna gro makes a "balanced" option in one bottle it's call all pro 7-7-7.
