I need to save these

[beensoup]

How do I save these plants
600wt lights
Cocoa / perlite mix and
Floating roots watertable.
GH flouro
RO Filter
69 t0 78 degrees
Ph 5.8 to 6.4
Plants get thriving and kikn butt. About a month into bud when everything looks awesome they begin to mimic Mg deficiency. The brand of nutes don’t seem to matter. The more nutes I have the longer it takes to develop the problem, but now my nutes are at the peak i can give em while the problem grows. The leafs that see any light start to get little spots til the outer vainal areas bleach and the leafs die. I'm looking from the underneath now and the spots are like transparent. I can see the light thru the spots. Soon i'll be able to see thru them. What it is is the whole plant seems to just want to frign die with deficiencies almost suddenly. I have been having this happen too many times now and I seriously need help. I thought I had it figured out when I dosed heavy with cal mag and they thrived. Til now. AGAIN! I'm now folier feeding with epsom salt. Another forum friendly person mentioned airborne toxins. They’re symptoms were like mine. I did find some toxic vapors nearby and removed it a day ago. I kinda hope that was it. I’m tired of staying up late trying to salvage this once easily grown weed. I have one plant in the last few months that doesn’t seem to notice. It was an experimental the was in 3 gallons of soil then put in a 5 gallon with cocoa and perlite. I treat it like a hydro plant. And feed it floronova full strength. It looks slightly over watered like expected.
But how do i save the others? your time spent will be really appreciated and Karma will pay you off some day.

How are they fed?

What strain is it?

cut back on the ferts and flush flush flush, allow to dry out and water with Mg disolved in water.

Then start back on a 1/2 strength nute mix.

Mango and some awsome no name. I drip the cocoa /perlite 1350ppm 5.7 ph enough to run off a bit . Other then that I have a floating roots table. 700 ppm 5.8 ph.Last time i flushed they got worse. I'll try to flush one first and see what happens. i usually flush every 10 days though. Loading up thte cal mag was getting me by but it seems like they are getting more Mg than they should but not using it? I like the idea of adding Mg after a flush n dry. i think I'll try it. i actually added just cal mag at 500ppm to them tonite. Kind of a cal mag flush.
Thanks

I read just now that
"Magnesium aids in the utilization of nutrients, neutralizes acids and toxic compounds produced by the plant"
Could my Mg be being used up to deal with the possible toxins i had near the air supply?

 

[beensoup]

THe plant is actually deteriorating fast

 

[beensoup]

Mango finishing 3 weeks early. it happens fast. Im assuming airborne toxins. i have no other explanation.

Plants Are Toast!

One table died the other dying. ***

Very sorry fella but i no clue what's the problem, hope you can work it out in future

Beensoup,

I'm in exactly the same position. It came on during the dark period and just spread like wildfire through the biggest leaves first. Sometimes it looked like MG deficiency and on other leaves it spotted first instead of starting at the tip.

I saw in one of UKGirls journals that something similar started and epson salts sorted it as far as i could read. They didn't work for me. The only thing I can think of as I flushed aswell is that it could be a root problem? Haven't the foggiest otherwise!#

It happe3ned on one plant that has about 2 weeks to go :/ the other has started to now a week later but that one isn't half way through flower yet :/

I hope I can get something out of the them

Hmmm, Let's fix this ****. My good buddy recommended hydrozeme to me last night. I'm going to the store today to get me some. He said his guru buddy swears by it and it treats roots.
I'm on like 6 posts right now but am consolidating to:hipforums.
you posting here i want to keep in touch with you and finger this problem out. Has you nutrients been stable? What are they and your medium, and all the specs of your grow.
Good luck to us.

u can post urls here, just change the "http" to "hxxp" w/o the "". man i read something not too long ago showing your symptoms, specifically i remember the transparency of holes in leaves, kind of like your describing. its not a hole, but almost a clear film correct?

 

[beensoup]

Really? ya real thin before they turn brown. Light leaks in the leaves. I found one guy asking but he never got a good reply. I'd do anything to find what I got. Almost anything.

Omg!

Omg!

Thats what we are all thinking about your posting !

What is a "floating roots watertable"? Are your roots exposed to the light all the time? A pH of 6.4 is too high for hydro.

 

[beensoup]

It seems to come to me in waves. I'm hoping it was a toxic air problem as I had evaporating lacquers and varnishis not far from my air intake and in hte same building I had a slow poly urathane leak. THis may not help you. It's still a mystery. When the plants were small they had an onset of it twice and cal mag and or epsom was used and they got right back on track. Now they are much bigger and it seems I can't get them enough nutes or mg in the same mix, I refuse to burn them though. I'm folier feeding epsom salt now. I want them to have the normal regiment in the water and figure I'll give em epsom externally since it's a mobile nutrient.
Good luck and please don't forget me when you figure it out. Same goes with me.
