When to switch to bloom nutes

I switched the lights to 12/12 6 days ago, and watered that day, then again yesterday. Both times I used full strength veg nutes. Curious when all of you switch to bloom nutes. I figured at least 2 weeks after the switch for the stretch then I'll switch to bloom. Thoughts?
 
If they showed sex within 5 to 7 days you can turn off veg nutes at week 2 or do half and half. If they took a couple weeks to show definitely stick to 3 weeks into flowering for the full transition as normally recommended. By the way plants that are mature will generally start kicking pistils after 5 days of 12/12 for me, but not always sometimes 7.
 
I had them in veg for 47 days and they were all sexed before I even switched to 12-12. So I should probably do my next feed as half and half and then after that switch to full bloom...
 
Yeah I would agree unless they are overly dark green or you otherwise have a reason not to
 
When you flip to 12/12 they will stretch alot.
keep feeding veg nutes untill they stop stretching . only then you should start bloom nutes.
so just keep an eye on their growth during this period and act accordingly
 
use both veg and bloom nutes together in veg and flower. so you have an even balance of nutrients and minerals.

Plants don't want high n in veg and high P in flower. that's just a marketing scheme to get you to spend more money. Plants want the same amount of nutes in veg and flower. except for subtle differences between cultivars. Some use more calcium, some use very little nitrogen, some use a lot of potassium, , some use more copper, some are magnesium hogs etc ...

around 3-3-3 or 5-5-5 through out the whole grow is what you want.

Mimic nature for best results. Veg nutes and bloom nutes don't exist in forests

I don't get the their out to make more money thing. I'm not an expert in nutrients and cut my teeth on MG lol, but my grow and bloom nutes cost the exact same and when I'm using one I'm not using the other so where does the more money come in to it. I guess if your using AN with their 20 bottles then yes but companies that use just two formulas would not make more would they? I have also found in my limited experience that using higher N products near the finish seems to prolong finish. Perhaps others have further insight into changing ratio's and if it actually helps. Pretty sure that most who actually use dry powders mix different ratios at different stages. I'm to lazy for that :).

more money by making 2 separate bottles instead of 1.

When you use bottled nutes your force feeding the plant. With a built soil plants feed on what they want when. they want and it's more balanced.

There's bottled nute companies that make an even balanced single bottle. Plus all the additives they try to sell you are unnecessary. It's just abuses the plants. look at advanced nutrients one of the worst nutrient companies next to scotts mg and monsanto owned companies. Advanced has about 20 different bottles they try and push.

there plenty of companies that don't do a b solution and have one bottle you can use in veg and flower

I'm not debating which is better re bottled, solubles or living soils. My methods vary depending on style with my indoor hydro using salts and outdoors using compost teas and organic nutrients. My point was that the money thing just doesn't make sense to me when talking bloom versus grow when they are the same price. But yes perhaps I'm missing something here. I do think that there is more to it then ripping off customers and a lower N is better but I could be wrong. I use the two formulas and my plants are very healthy till chop, it did take a few years to get there though lol. I do use half and half through the stretch then switch to bloom. FYI I did mention that yes possibly AN is in a league of its own when it comes to raping people with its 20 bottles lol.

You don't really need to change your nutrients from veg to bloom if the leaves look healthy.

So why the two different formulations then? Is just a total waste? Would you get the same results by just running veg formula? I am not trying to say anyone is wrong I just don't know why they would offer two if one would be just as good?
 
The reason most hydroponics formulas use a+b or 3 part formulas is because of the nature of certain element combinations wanting to precipitate out. (particularly high concentrations of calcium mixed with phosphates and/or sulfates).

A+B bottles makes sense even if you make the stock solutions DIY from scratch. The calcium goes in A along with anything that's compatible with calcium, including iron DTPA or EDTA. Everything else goes in B. (phosphates and sulfates)

Edit: The companies that offer a complete hydro formula in 1 stock solution are pulling off something most can't. I would guess that dyna-gro actually makes a compromise to do this rather that companies offering A+B not knowing how to emulate dynagro. The biggest compromise is likely to be shortened shelf life. You can also get much higher stock solution concentrations with an A+B although is is moot point if you're not doing DIY nutes.
 
I do know why there is an A and B, the question was about veg versus bloom and why there are two when one will suffice given they are the same cost. do you keep the same ratio of salts for all stages of growth or does the amounts of each change with the cycle?

Actually it would be cheaper to market one bottle with one label versus two bottles, two labels. Only one line needed to run the bottles and less mixing. Well actually two versus four if taking into account A&B :).

Small changes to NPK to tweak results at different stages may help a bit, but it will still work fine if you use 1 formula from seedling to harvest. I guess my original wording wasn't clear. You don't really need more than one formula, but it might help a bit. I personally do not have separate bloom and veg formulas, at least at the moment and it doesn't result in deficiencies when I don't get lazy changing the reservoir. Without having a large sample of plants for experimenting, it's hard to know which tweak at which time is making an appreciable difference so I figure why bother.
