Do I need to do anything to see the pic's?

Pictures Are There Now.
Thanks

Whats your lighting system. This could just be a burn. But, this far gone, I don't think these plants will be saved. At least, not the first six.

Whats the temperature in the room too? Over 80º F and your asking for some major wilting. But if you've been doing this for a few years you will know that.

ok, you have bad ph. The plants in the first pic' are clearly overnuted, and the second are sufferring from deficiency. Complexing, i know especially as you've most likely been feeding them the same way.

Which is why this is a ph problem. The ph of your medium has reached a point of lockout. In trying to correct this problem you have most likely treated for deficiency in the first set of plants with correct ph and severely overnuted them.

I can only imagine you have tried the same thing with the other set, only that the lockout has saved them from the same fate.

The first set of plants may take 2 weeks to recover which is a lot of weight lost, after flushing, and plain ph'd waterings.

The second set will recover quite well after a normal ph'd feed. How have you managed to get here? Do you have a ph meter?

Actually, on closer inspection, the first plants are severely undernuted too. Not overnuted. sorry.

definite ph lockout in your medium.

I Leached Them About 2 Weeks Ago When The Leaves Started To Look Like Plant Pic 2. I Leached Them With Water That I Adjusted The Ph To 6.5 After That I Put Just All Purpose Fert In, 1/2 Gallon In Each 5 Gal Pot, Mixed 1 Scoop To A Gallon. We Tested The Soil Before Leaching Them And It Showed Ph Was Good On Most, A Few Said It Was Low. I Only Tested 3 Of Them For N & K In The Soil And They Were Both Low. Thats Why I Just Used The All Purpose Fert To Bring Up The N & K.
Prior To Leaching Them I Tried A New Bloom Fert Pictured Below. The Plants Weren't Looking To Good, So I Thought I Would Try Something New. I Also Need To Mention That 3 Out Of The 6 Plants Were Clones From The Same Plant. I Don't Know If That Matters Or Not. The Plant They Came From I Had To Cut Early Due To What I Believe Was Aphids. I Cut Everything Down And Sanitized The Room Before Moving New Ones In.

As Far As The Lights, We Have 3, I Don't Remember Off Hand What They Are, But We Have Been Using The Same Ones Since We Started And There Was Never A Problem Before. The Tops Are At Least 18" From The Light And They Are Not Directly Under The Light Itself. Lights Are In Center And Plants Are Along The Walls Of An 8.5 X 3.5 Area. The Temp Goes Up To 85-87 If It Is Kept Closed, But We Normally Have It Opened. The Temp Now Is 74.

I'm Getting Ready To Cut Down 3 Of Them Now. I'm At A Loss As To What To Do With The Others.

Thanks
