well heres i think most of my questions
- when using Dutchmaster nutrients they recommend 1000ppm @ .5, which is 2.0ec. you're saying that running maxibloom ONLY at 1ec (500ppm @ .5 conversion) is sufficient during flower?
First rule of growing: Forget nute recommendations, they're bullshit.
Second part of your question, no, 1.0ec is only for maxigrow in veg. It also applies to any other nutrient structured like maxigrow (in other words a proper base feed with a similar NPK ratio)
- whats the ideal PH in dwc for flower and veg in your opinion? 5.6-5.8?
I don't grow DWC mate, I'm in coco. I would say don't obsess about getting the perfect answer. The DWC boys usually say to set it at 5.6 and let it drift up to 6.2 or thereabout. I'd say you won't go far wrong with that. It makes sense.
- some people use koolbloom late in flower, do you think its necessary, meaning will it add extra weight to the final product?
This is a good question. On a high phosphate feed like maxibloom, I can't see how adding in even more phosphorus would benefit the plant in any way. It's something that doesn't make any sense to me. I can't see any way that extra phosphorus would be used. Put it this way, if you compare maxibloom alone to other standalone nutrients, the ratio is close to where you'd be if you were already using a pk booster to adjust your nutes.
So, in short, no, I don't think adding koolbloom will be of any benefit in terms of adding size and weight to your harvest. The only way to know for sure is to use it in a side by side.
i purchased cultured solutions bud booster which is basically very veyr similar to koolbloom. i used the recommended dose of 1/4tsp per gallon (i added 2tsp for 10gallons thinking it'd be strong) and my PPM was only at like 300 (which is i believe 0.6ec). so i added some maxibloom also at half dose which brought it up to 1.4. since thats only 700ppm that seemed low compared to what DM recommended on their bottled nutrients so i added 2 more tsp's bringing it up to 1.7ec.. should i drain and refill at just 1.0ec? and should i bother using the bud booster or just maxibloom? i understand that maxibloom will work good enough, but i guess my main wonder is if using the bud booster is going to add weight to the final product or if there is absolutely no benefit at all.
If the NPK ratio of two feeds are the same, it doesn't matter which one you use to get to your desired EC. They all use the same chemicals, every one of them.
Whether there are PGR (plant growth regulators) in your product or not is what you need to find out. That will be the only thing which could be different other than the NPK values of them.
The second part of this question is answered with your last question in the post at the bottom.
- i have read that if you are using lower EC's (1 is pretty low) then you wont really have build up in your plants and no flush is really necessary. if running at 1ec would you recommend a week or 2 of water only at the end (in DWC), and if so, how long?
Again I'll answer some of this at the bottom. But if you're in the right range with your feeding, as soon as you take away the nutrients your plants will begin to pale, so very little flushing is needed. You don't want dark waxy looking leaves and burned tips on your grow. You're aiming to get to the end without that. How well you do it depends a lot on experience and learning grow after grow.
also do you see any benefit to using half grow half bloom first 2 weeks of flower? seems that it would provide a more balanced amount of potassium and nitrogen, leading to not only healthier foliage growth during the stretch, but more budsites due to higher levels of potassium. or would you just go full on maxibloom from day 1 of the switch
This is a good question. For the first week or so of flower, the same feed that got you through veg will be just as good in that week of stretch. You might need to bump it up by 0.2 you might not. Read the plant to know. If the bottom leaves pale at any point, that's your cue to up your feeds. If your plant is too dark, waxy, or gets slight minute tip burn, back off by 0.2ec.
As you get deeper into flowering the ratios need to change, you're right. Now.. this is where you stray into territory which no grower can ever tell you exactly what is the perfect thing to do for your plant.
If you look at the maxibloom, like I said before, it's a high phos feed. Now, people say use high potassium in flower.
This is where you're delving into the territory which will ultimately separate your results from the next person's; the incremental difference between good plants, very good plants, great plants, and perfect ones.
You can, once stretch is over, just stop using the maxigrow and switch to maxibloom at full strength. Loads of people do and have no problems.
But, if you mixed them 50/50 you'd also have a very good ratio of nutes for flowering, and would also be able to use them at a lower strength (closer to 1.0ec) without the plants fading from the immediate removal of the nitrogen.
You could also, if you felt your plants didn't need any more nitrogen in their feeds, drop the grow for that week, and so on.
All these things are dependent on your ability to read your plant, know what a good calyx to leaf ratio is, notice the signs of excess nitrogen etc. All these things will come naturally in time if your focus is on the right things, which it seems it is, rather than on magic potions. The maxi grow and bloom will give you the ability to tweak and adjust your nutes to whatever you think is the perfect point for you and each of your strains.
For now, if you're not experienced in doing these things, just get some basic grows under your belt and the rest will follow.
