I alt. weeks with epson spray and fert.

I don't know, my advice is to not get too preoccupied with being exact. I did and finally realized it doesn't matter that much..

I remember when I started my bhut seeds I was watering them to the cc, and trying to keep the temperature within 1 degree hahahaha, the 2nd batch I just let them go on a heating pad and had the same results.

You'll get better results just pouring the mixture onto the roots. Foliar spray doesn't really do much for a healthy plant.

I dissolve a golfball sized chunk into a 5 gal bucket. Not very scientific but the results are noticeable to me and I dont think the plants need alot of these minerals. I also second doing a root feeding and dont waste your time with a foliar spray.

i tried spraying my pepper plant with an epsom salt solution of 1 tbs to quart of water. i never saw a difference after a month. i did see a difference when i used a foliar calcuim in combination with seaweed extract and fish emulshion. am i doing something wrong? i know epsom salt has sufur and magnesium in it. would it be better to put it around the roots with the sulfure content in the epsom?

Its always better to feed through the roots unless the plant is so badly damaged it simply cannot use the roots anymore (like if its a cutting, or has extensive root rot, etc).

The plant is designed to take nutrients up through the roots, and thats what its best at. The fact it can absorb a small amount through the leaves is just a happy accident.

I have yet to meet anyone that has done controlled tests that has found foliar feeding to be superior to root feeding (controlled as in put a sheet around the stem so the foliar feed doesn't drip onto the roots).

All the research I have looked at shows that epsom salts are pretty useless when applied to the soil/growing medium unless you have a significant deficiency there. What *is* effective is using epsom salts (Magnesium sulfate) as a foliar spray. One possible reason for this is that magnesium competes for uptake at the roots with calcium and potassium. So, you could have plenty of mag. in your soil, but the plant won't take it up because it needs calcium or potassium more. But, this does not happen when you're using a foliar spray. So spray those plants!
