How much Epson Salt?

[Guest]

I used RO water my 1st grow with EPSOMS and got mixed results... I have been using RO water with added Cal-Mag every other feeding and my plants are blowing my mind this time...

wondering if anyone could help?

currently have some bubbleberry on the go in nft at the moment day25 12/12. plants have symptoms of mg problem.had a pretty stable ph normally
starts @5.5 and drifts up to about 6.0 over say a week.

got some epsom salts today and when id topped up my res and bumped up the feed to 1.5e/c,then mixed epsom salts in hot water with hand blender and added it to the rez.after another good mixing i put the truncheon in my soloution and i had an e/c of 1.8 is this supposed to happen?

any help would be very gratefully recieved.do i need to dump the res and start afresh?the doseage i used was 1 teaspoon(level) per gallon.my rez size is 40 litres.

your allright bro............. your adding salt to your rez witch makes tds rize....
just make sure when u add nutes add this last or first so u can keep a eye on your tds/ppm......
if u add it first make that reading your start point....
its kinda like taking your tapwater away from youe nute ppm.....
(my tap water is 270ppm) so when wanting 1500 ppm i make it 1720 then add calmag & it go's to 1950.
your using ec n im using ppm but its the same....

Too bad most of the dam US has crappy tap water....not evn worthy of a weed . I won't even give my animals this 350+ ppm garbage.

I'm on a community well, water is 450 ppm @ ph8.5 from the fossit The best $125 I ever spent for my grows was the RO water system on e-bay. Now PPM is 20 and PH is 7

70s

Summabitch, that Cal-Mag is looking better all the time!! Hell, I spent over $500.00 for my AN nutes. What's another $30.00 or so for results like that! Great job, bro!!

 

[Guest]

LOL, Thanks dude..... Seriously tho I will never use EPsoms again, IMHO Cal-Mag & Liquid Karma are a must when using RO water in my garden...

Hey I just wanted to give everyone an update on my girls. I fed them a teaspoon of epson salt for two watterings and 1/2 per gallon now for every wattering and the problem has cleared itself up

here she is at 26 days flower

where can i get cal mag in the states , jahbless

 

[Rellikbuzz]

She looks absolutely beautiful, Samson! Nice work, my brotha!! Just a suggestion. You can remove those larger, yellowing fan leaves if you like as they as not getting much light because of all the foliage. In fact, many growers will remove some of the lower and inner leaves that don't get much light as this, ultimately, helps the plant to breathe more easily and also will help focus the auxins (the growth hormones in the plant) towards the tops where you want the most development. As I said, just a suggestion but it is a sound practice to do. All in all, everything looks like its back on track and going well. Keep those pics coming as she continues to develop!!

 

[JAHBLESS]

got my cal mag plus , high times a comin

Epsom with every watering in flower? Sounds a little overkill. I hardly use any of the stuff and do just fine.

yeah to me epsom salts every watering seems like way too much.

 

[talktosamson]

Just to let everyone know, the Boggel came down a few days ago, shes dryed and curing in a big glass jar in my closet, final weight was 30 grams, not too bad for a square foot and a few CFL's in my bathroom closet....shes still got that fresh cut grass smell, but I can detect the sweet undertones she will have in about a week

 

[Verite]

Curious as to what sweet undertones you may be experienceing from the bathroom?

You'll want to add the epsom salts with EVERY watering now until the end of flowering. Initially, I would put 1 teaspoon per gallon for the first few waterings and then back off to 1/4-1/2 teaspoon per gallon the rest of the way. Also, and this is very important, you'll want to dissolve the epsom salts in a cup of very hot water before adding it to your nute solution. Otherwise, the salts won't dissolve and the plants won't be able to take them up. Good luck!

Does this still sound an ok mix? I ask because the thread is a few years old and things/info change.

It seriously depends on what kind of grow you have, soil, soilless or hydro, your water quality and what kind of nutes you feed ?

The post you quoted would be a serious overkill in many soilless grows for example with certain ferts.

Tru dat

Would this be a alright mix for soil with bottled spring water? Not using ferts yet..

Sometimes the bottled spring water sold as 'drinking water' is processed with "minerals added for taste" after its been filtered. This is usually sodium. Look closely at the label when buying bottled water. If it were me, the only bottled water I would buy is pure distilled water or pure ro water with no further so called "taste" enhancements., not the "drinking water" kind. The sodium content in some of these 'drinking waters' is enough to cause the plants to look deficient in micros and P, so beware of the water you're using first and foremost.

It's worth trying aged and degassed (aerated to remove chlorine) tap water as it usually includes some calcium, mag and other minerals. But on the other hand some city tap water is just garbage with additives like flouride., chloramines and sodium, making them unusable for healthy plant watering.

A vegging plant in a soil container, I would go with a one time shot watering with a teaspoon or two of epsom salts per gallon, no more than a tablespoon per gallon. I prefer to start with less and see how the plants react. Easy does it. The plants should show a noticeable improvement if they're needing magnesium or sulphur. Beyond that, I'd wait and see if and when they're looking for more mag. Good soil mixes usually have dolomite lime in the mixture and you shouldn't be seeing a need for mag in a youngster vegging.

Later on when the plants put on a good amount of foliage, you'll be starting to feed ferts and they often have enough mag included, but some need a just a tad more. GH flora mineral chem nute mixes for example can stand for about an eight to a quarter teaspoon per gallon added to the mix for the plants that are "mag hogs", especially if you're working with r.o. or distilled water. Dissolve the epsom in some warm water before aadding it to your fert mix.
