There's no Calcium or Potassium in Epsom Salt. It's basically Magnesium Sulfate (MgSO4). All though to be more accurate what's commonly sold under the name "Epsom Salts" is the heptahydrate form MgSO4-7H2O. While it's useful as a source of Mg (magnesium) it is a salt. And if not used judiciously it will only further increase the salt levels of the soil and make "fertilizer burn" worse.Many haters would disagree but, these pics look like their a little unhappy. What I would do is I would consider what the soil PH is, the big thing with growing indoors is the soil will draw in salts, this will prevent nutrients from entering the plants roots. As an organic grower I find things to use without spending a fortune and using chemicals. (organic chemicals in bottles are not true organics) Use a Tblspn Epsom Salt & Tblspn of Mollasses with every fert. Start small amounts and work up. People seem to expect great things from these items and dismiss them as useless because they try it out expecting gigantic buds. This is not possible with any chemicals. The key is to keep the flow of nutrients even and healthy. The Epsom Salt equalizes ph (because of calcium) and has potassium and other things a plant needs. The mollasses (surgar) enrages the micro organisms in the soil and breaks down everything to a form easier for the plant to absorb.
You dont have to try this but I am only suggesting this because I believe this will solve your problem. Proof be on the left, very little ferts, all natural.
dshot,Im leaning toward magnesium deficiency.
Soil is Fox Farms, I fertilize everytime I water - around 1000 ppm using 2-3-5 Bloom formula. Water is RO water, and is PH tested/adjusted each watering - I keep it in the yellow, so around 6 to 6.5 is probably a good guess since I dont have a digital meter and only go by the color legend on the kit. I water the ladies every two to 3 days - I use a meter to measure the moisture in the soil to see how they are. I recently bought a 2-0-0 Mag to add to the mix, only gave it once so far. I think Im going to flush today - then next water give extra 2-0-0 to this one that is a little upset and normal nutes for the other 3. Any other recommendations or thoughts? ill also consider the salt and sugar...
...I believe your onto something.dshot,
Considering the above it really sounds (and looks) to me like you've way over feed them and have to many of these different salts built up in the soil. It also sounds like you're keeping them way to wet and drowning the root system. I've got plants that have way more foliage on them than yours in containers about the same size and I only water them about once a week.
I think that anything else you give these plants at this point is only going to make it worse. About the only thing I can think of advising you to do is give them a dam good flush and then don't water them so often or give them anything else. If they were mine I'd set them in the sink or tub and pour 5 gallons of water thru them for a flush. And then leave them alone for a week to ten days.

Read the back label. It has it all baby. Thats why it works.,..There's no Calcium or Potassium in Epsom Salt. It's basically Magnesium Sulfate (MgSO4).

If your problems are due to the soil already being to acidic the SO4 (Sulfate) component of that compound is only going to make it worse by further lowering the ph.

O.K. you just keep believing that. *snicker*Read the back label. It has it all baby. Thats why it works.,..
And pigs can fly. Yes it works, but for the reasons Jack stated.Read the back label. It has it all baby. Thats why it works.,..

I had to laugh at that Epsom salt statement as well. Most growers don't realize just how much sulfate they drop into their reservoirs, especially with blooming supplements. At ideal pH levels that sulfate is mostly unavailable to the plant but still available to create salts when/if the media becomes dry and it drops out of solution. I personally avoid anything with sulfate in my coco systems if I can because of the electrical sensitivity with calcium and potassium, both highly reactive with sulfates.
