im runnin a 200watt cfl - my first cfl grow

GL??
i will consider iron and see what i can do. thanks for your imput.
i thought it may be Mg.

the plants have had this problem for a while, since their first to second week of veg. alot of leaves have been lost.
recently its been spreading faster.

the yellowing started at the bottom pair of fan leaves, and moves upward attacking the next oldest set of fan leaves.
note it varies per plant.

should i use epsom salt in all future waterings?

would the normal dosage of epsom salts diluted in water cause a build up of Mg if i never had a Mg deficiency in the first place?

so many questions, im just feeliin a little panicked

From your first photo I am sure light density is a problem. You need several more bulbs spreading light over the plant canopy. That means at least double or triple the Watts you have now. The lamps must be within a couple inches of the tops.

If light density is inadequate, nutrients will burn the plants, and plant performance will be poor. Light density controls nutrient absorbtion.

I am using 1700 watts equivalent on 12 plants.. its not actual 1700 watts, much less, but still about 140 watts per plant. (6500k household cfl's, 17 @ 100w equivalent each) your plants are much bigger than mine also, mine are maybe 10 inch tall max, and in hydro. point being that you need alot more lights and alot closer, my lights are 3 inches off the tops.

Frankly, with as little light as you have provided, I am amazed those plants look half that nice. You may have a nutreint problem, but no one can tell for sure untill you have more Wattage over the tops of those plants a few days.

I'm curious to what your problem is because I'm having a similar problem with just a select few plants we have. Brown spots and yellowing of the leaves with green veins. I have been using epsom salts regularly so I know it's not that. I have been giving enough ferts, so maybe its over fert. The only thing I'm not sure on is the water and PH of the water. We went and got a bunch of distilled water and are going to use only it for now on with no addatives to see if there is a difference.

And it's not the light, we have coverage over all of our plants with about 400w of cfl's and 80w of led's so I know that is not your problem. Let me know if you see any improvement.

Distilled water is ph 7.0. You need about 6.0. That will cause a big problem with some strains.
