TR-Did you pre-soak your media in pH corrected solution? Well, no. I did soak in pH water, but not for as long i should have


Below are a few pics I took to day. I noticed the brown spots on friday, and immediately thought nute burn, so i dumped the water and refilled with normal pH water no nutes.

This is a 10 gal res, 11 plants. Not all the plans are having the problem. Some are doing just fine while others arnt.

I have been using the TechnaFlora suit of ferts and nutes. Followed their instructions, but not going full strength. They say to add all this to 1 gal of water, but im not sure if the 1 gal is enough for all 11 plans, or if i should have been adding the nutes according to my 10 gal res.

So i guess my main question is nute burn or deficiency? Since changing the water, i have begun feeding them via a spray bottle individually, using a very diluted nute solution.

Images 1 and 2 show the problem plants, pic 3 is healthy. Again, same water source for all.
