Calm/mag in the flush? Isn't the point to get rid of the build ups and not include something that'll add to it? (I'm not being as smart ass, I just don't know)

I guess that depends,how much of a flush?Like putting in the bathtub and running 20 gallons through?Or just a little runoff?

Unfortunately I cannot switch to bottled nutes because I need to be away from home sometimes 2 weeks at a time and it's much easier to have friends just water the plants than mix nutes and feed them. So from the research Ive done, its not go to go below 6.2 with organic dry amends because it starts killing good stuff in the medium. But I can try going on the lower end and ph'ing around 6.2 to see how it goes.

Mix a couple gallons at a time... that's what I do. Then my buddy comes over and waters them when I'm out of town. I'm out of town pretty much every week.

Running 2 gallons through 3 2gal pots. So about a gal or so of run off in total between all plants

Flushing is a major debate here. its getting better though. this site is much brighter then it was in 2008 when everyone knew everything. The word "flush" , the word "salt" and several other words need to be ammended for new studies.
For example. we think we have a "salt" buildup so we want to "flush" the salt out..... its not that simple at all. Some of what we are calling "salts" are not just going to run out the bottom with water.....some will and some wont. Some of that food is bound to coco/soil/peat particles on a molecular level and cannot be "flushed out" Nitrogen is one that is very easy to flush out of the pot with water but P and K not so much. they tend to stick to roots and soil.
Basically , the word "flush" has been altered to newer styles. when most tell you to flush , they mean just water only so the plant can eat whatever is left over without adding more.
These guys know more about coco then i do so when they say add calmag to your flush then thats what you do. They are assuming you have no build up of cal or mag so skipping that would just make it worse.
When i use the word flush i will give directions but mostly i mean a flush with a balanced diet of around 5-600 ppm. (that way if you wont throw the nute ratios off by flushing out the N but not other elements. )

im pretty sure your math is off on the 1ml being those numbers but i may be wrong. Your ratios are fine and thats what matter more then the concentration of the food. if you have a 20-20-20 then i would use 2-3ml per gallon , twice in a row to get them back on track.

You are defoling bigtime so take into consideration that the plant will need slightly less food since its a lot smaller of a plant now.

All the different nutes multiplied by the ml/g and added together comes to the figures I came to previous, math is 3x checked ha. So basically what I have in my reservoir is 21-20-31 at 1 ml per gal so it is a little lighter of a dosage than you are suggesting, however there's enough in the reservoir to feed 3 times instead of the 2 you suggested. Also with the defoliation you mentioned, I think thinking 3 feedings with this ratio will work. What do you think?

What exact kind of light are you using? how many actual watts does it use ?
Click to expand...
Its "1000w Led" grow light (https://www.amazon.com/gp/product/B0185OLBPK/ref=ppx_yo_dt_b_asin_title_o04_s01?ie=UTF8&psc=1). I think the actual wattages pulled is around 180 true watts. Probably a piece of crap light compared to what you are using haha I really regret getting the blurple spectrum, its hard to tell deficiencies in the light and taking pics of the plants under the spectrum is a nightmare.

I am thinking about putting together a mixture that will total to 6-5-8 and put in at 1ml per gal. This mix will have a good amount of micro nutes in it cal, mag, silica etc as well.

1ml? seriously? 10 minimun maybe 20 per gallon shit i use 30 ml per gal of tigerbloom they love it

I have increased the strength and the ratio since that post, but my logic behind the low dosage is cause I am also using slow release dry amendments in the soil as well, and its impossible to know that ratio that is being released, so I didn't want to over feed them. So I started slow and increased the amounts.

Best ratio is 1-1-2

Weed likes 2x the amount of Potassium as it does either Nitrogen, or Potassium.

Id shoot for a 20-20-39 and adjust the PPM accordingly.

The plants also need Calcium, and Magnesium. Those spots are calcium deficiency, and also consider Magnesium is the #1 container grown plant deficiency, and add in weed is one of the highest consuming Mg plants there is, and you see that weed needs a constant supply of both. Both are also Electrolytes, and responsible for cell communication. I believe many Cal/Mg supplements are 2-0-0? So take that into account.
