Anyone using Epsom salts ??? How often ?

If you a using a complete nutrient program, it really shouldn't be needed at all.

thats if he have a micro/macro feed. If nof u should use calmag or cheap way epson salts and grinded egg shells in your watering schedule, but dont use epson salts in EVERY WATERING GL

I only ever use if I see a deficiency. You use it with one water you probably won't need to again.

If you use crab shell meal in your mix you probably shouldn't have an issue.

I do use it when i water my tomatos every other watering once they get 'maters growing on em. It helps sweeten em up. Using the same approach to your cannabis though could leave you with a lockout.

Most pre-made potting soils, especially if you add some of the high quality meal amendments will have you all set for magnesium. Fish hydrolysate has magnesium, as does molasses if you're using that. It's pretty easy to have it covered but Epsom Salts are good to have on hand in case your plants need a quick boost.

I use it anytime my Magnesium ppm's drops below ~50ppms.

I add only till I hit that number.

Purrrrty good advice id say.

Agreed, but most of the additives I use are sulfate related.

Target Sulfate ppm's are also 50 ppm's.

Well all I am using in my pro mix is .... A fert mix that has the following ...Ingredients: Alfalfa meal, bone meal, blood meal, glacial rock dust, mined potassium sulphate, fossilized carbon complex, rock phosphate, greensand, kelp meal, gypsum.

Only reason I'm asking about Epsom salts is because I noticed a little purpling in my little lady's

Could be genetics or deficiencies. More info helps diagnose, if there's questions.

...and of course, we're very photo friendly here.

Lol this is my first real attempt at organics ... Deff felling new lol

When I use epsom salt, I use it every other watering with fox farms happy frog soil. For nutrients I use fox farm grow big and tiger bloom nutrients.

Ex: plain water on 8/1 (ph between 6.5-6.9); 1 tsp of nutrients on 8/4 (ph 6.4-6.9) ; water with 1 tsp of epsom salt on 8/7 (ph 6.5-6.9); 1 tsp of nutrients on 8/10 (ph 6.4- 6.9); plain water on 8/13 (ph 6.5-6.9); 1 tsp of Nutrients on 8/16 (ph 6.5-6.9); water with 1 tsp of epsom salt on 8/19 (ph 6.4-6.9). would be my schedule.

I get leaves like this. The Epsom salts clear it up.


Once the leaf discoloration stops, then I stop using epsom salts.

Yea i can see how that mix might leave your plants needing some magnesium. Do 1 tbsp per gallon of water, wait a week and a half and then do another feeding if they're still deficient but it usually doesn't take much to clear up.

K levels effect purple or better put, enhancing the coloring the plant is able to do.
I like higher K levels in my runs. That doesn't answer your question!

A little purple could mean several things. It's something that could mean nothing to really concern you,, to a problem that needs to be addressed.

The pic's asked for would be the only way for some of us to tell.
