I'm pretty sure I have a magnesium deficiency. I've only been watering with water, no nutrients at all. It's in 5th week veg. I added 1 tsp epsom salt to the water. My question is, how long should I water with the epsom salt & also should those leaves that are spotted be removed or will they get better? This is my first grow so I don't know much!

once a leaf shows damage it will not return to normal.

Until it's obvious that you need other nutrients ...
There's not enough info here. One teaspoon in how much water? Epsom should be dosed by weight. One gram in a liter provides 100ppm Mg.
Since you're not providing nutes, and you've said nothing about your soil, might you be having a classic NK deficiency? cn

I've grown in Happy Frog and noticed that it was a bit light on Mg for my plants. I would water thoroughly once with your Epsom solution. If things don't visibly improve in a coupla days ... it's something else. cn

Without pics of the affected plants, I can't provide as good a sort of advice as I'd like.
However, I'd leave (!) leaves attached if they still have some green. That's the plant's way of saying "not done with it yet". Jmo. cn
l33tganjaman, i tried to respond to your PM but you need to clear some space. cn

In Happy Frog, I got away with just water for over 2 months. But that's one data point. Your MMJileage may vary.
I don't recall ... did I ask about your water's quality? What are its ppm out of the tap? pH? cn

You say you transplanted "from Happy Frog to Fox Farm". Happy Frog is a Fox Farm product. By the pics, I'm guessing you transplanted to Fox Farm Ocean Forest. The plant looks like it has been experiencing too much N. I don't think that is a Mg def so much as nute burn/overfert. Recent bags of Ocean Forest have acquired a rep for being "hot" or liable to burn young plants.
In which case my advice is to replant in Happy Frog ... or simply to keep going in that pot. The plant will recover, so long as you add no more nutrients and use low-TDS water.
"MMJileage" was a pun on mileage and MMJ.
ppm refers to parts per million, the usual units for TDS measurement in the States. cn

Look like the effect of high PH stop adding shit lol
would it be too much stress on the plants to re-pot at this time? they are in 5th week of veg & are only in 1 gallon pots. the plants were great until about 2 days ago when i saw the spots. or if i leave it how it is, will they be ok? should i add some N? sorry, i'm so new at this.
