How to flush when using miracle grow soil??

Hey guys,

so the girls have roughly a month left (possibly a little more). I am using MG potting soil which feeds for up to three months. They have been budding in this soil for only about 35 days. Ive learned the importance of flushing over the past couple harvests and I am wondering what would be the best method to flush these plants before harvest time? I have contemplated using a hose to wash the soil off the roots and putting them in a tupperware container filled with water and an air stone in the bottom. Then putting the 1000w light over them to keep them healthy and flush the nutes out for a little over a week... Duno if this is realistic or if there are better methods available? Anyone overcome this problem?

Thanks in advance guys.

i would not transplant them...you are going to run into a ton of issues there...just flush them with plain ph'd water using 3 times the amount of water as the size of your pot...so if they are in a one gallon pot...flush with 3 gallons

Ok. So no transplanting. So just flush them with ph'd water? How often should i do that in the two weeks before harvest? Keep in mind were talking about miracle grow soil and water causes a release of nutrients. Will the flushing allow all the nutes to be washed away?

Oh and can you guys give me your ideas on the problem i posted here : https://www.rollitup.org/indoor-growing/390414-how-give-bloom-nutes-if.html

Thanks for the help guys.

flushing wont remove all slow release nutes...but it will remove all the built up salts in the soil...and i dont buy the it feeds for 3 months stuff....half of the lil beads are dried up after a month in most of mine....MG dont take into account the lights that are being used...if your soil dries out...and you have high powered lights over them...those lil nute beads are going to dry out....so the flushing is more to remove the nutes and salts you have added to it.and flush it the same as you would do normal waterings...flush with 3 times water to the size of your container...let it dry out as normal...flush again.......and to answer your question on the other thread....use them as they are label....i would wait till about day 20 of bloom to start bloom nutes...but i guess that all depends on what you use...i use jacks classic for all my grows...and i give them a mix of grow and bloom their entire life cycle...but all nutes are different...i wouldnt do that with nutes with a higher npk ratio

awesome. thanks a lot for your help bro. It's helped clear up a lot... Any way to give you points or credits (like props points)?

One more question, how does mg soil work anyway? Do those little beads release nutes when they come into contact with water? Or do they release nutes after they dry out? You would think the beads would all release at the same time if they expand and pop when in contact with water...? How come this doesn't happen? How is the nute release controlled so no overdose occurs? Ive always been confused on how the MG soils work.

Ok so ill just start out using 1 teasp. once per week of the blooming nutes, it is 5-15-14.
Just curious but Jacks bloom is 10-30-20 with higher levels of magnesium, does that mean it has double the strength of Nitrogen and Phosphate? Or is that just saying that is the ratio in the mix compared with other key ingredients? What do the higher / lower percentages mean here as far as strength?

Thanks again for all the help.

edit: oh just noticed yr avatar. Thats sick, How did you make an animated gif image? lol i thought that was pretty cool...

not too sure on how the MG nutes really work...i guess its like a gel capsule pill like effect...after time the shell just bursts i guess at different time during and after waterings...ive seen them in different sizes..that might be how it works...the bigger the bead the longer it takes to release the nutes.

and for the jacks bloom...i wouldnt say that it has double the amount of N or PH....im sure it factors in all the micro nutes..that might effect the overall ratios of it all...not too sure...here is what the site lists...all that really matters is that your getting more phosphate then any other elements during bloom......
All fertilizer labels must follow the same format according to the state fertilizer laws. In Blossom Booster 10-30-20 the first number is for Nitrogen. This product contains 10% Nitrogen. The second number is for Phosphate. This product contains 30% Phosphorus as P2O5. The third number is for Potash. This product contains 20% Potassium as K2O. These three elements; Nitrogen, Phosphorus and Potassium are the major elements in any plant food.

Carbon, Hydrogen, Oxygen, Calcium, Magnesium and Sulfur are the secondary or minor elements. The water, soil and air provide most of these elements to your plants.

Manganese, Iron, Copper, Boron, Zinc and Molybdenum are the trace or micronutrients. All Jack's Classic products contain these trace elements. Although they are present in small amounts, they are just as important as the major and minor elements in making your plants grow. The guaranteed analysis on each package of fertilizer tells you how much is in each product. Jack's Classic products contain these elements in a highly soluble form which means they will go completely into solution in water, and when applied to your plants, they will be taken up and utilized to make your plants grow to their fullest potential.

Total Nitrogen (N)....................................... 10%
5% Ammoniacal Nitrogen
5% Nitrate Nitrogen
Available Phosphate (P2O5)....................... 30%
Soluble Potash (K2O)................................. 20%
Magnesium (Mg)......................................... 0.5%
0.50% Water Soluble Magnesium (Mg)
Boron (B).................................................... 0.02%
Copper (Cu)................................................ 0.05%
0.05% Chelated Copper (Cu)
Iron (Fe)...................................................... 0.10%
0.10% Chelated Iron (Fe)
Manganese (Mn)......................................... 0.05%
0.05% Chelated Manganese (Mn)
Molybdenum (Mo)....................................... 0.0009%
Zinc (Zn)...................................................... 0.05%
0.05% Chelated Zinc (Zn)

as it comes to the magnesium..thats all that ive noticed that sometimes the plants dont absorb enough with jacks classic...but that also seems strain dependent...my new plants i have yet to have any problems with it uptaking the nutes...my last plant i was using epsom salt to cover the lack of magnesium...wasnt using it each watering...just when i could tell if was lacking in magnesium

and for the avatar...thanks man...i do graphic design/web design...ive got a few video/picture editing programs...most of the adobe line and a couple gif animator programs...things i play around with when im bored and high.....and has for the "props/credit" no need bro....just hope i can somewhat help the newer growers thats going through the sames things i did...had a few people on here help me as i went along...when i started growing again id never grown in soil...always did nft grows...bigggg difference switching between the two

MG isnt flushable youre supposed to flush two or three times, flushing not only gets rid of salt but chems too. mg being how it is your plant may be stuck with some chem in it.

since its time/slow release nutes...its flushable...but can never get all the nutes out...just all the nutes and salts thats built up...either way flushing is good..no matter what the soil is
