Spots - Bad - Urgent

Wow. Ok check it. I have two mediums, Floating water I'm good at and Cocoa I've done well before in. I get the puppies all beefy and ready to bud. They were even stinkin. I up the nutes with AN 2 part sensi grow - cal mag, ro filter, appropriate levels, Diferent for each. I switch the nutes to bloom and I get what you see in the pic, Very bad. It happened the very next day too. I have plain water in the systems now.
Any Ideas? I'm out.

Almost same prob man. Using the sensi grow combo..... but im begining to think it may be a bit harsh.... anyway, weird question.... How close is your light (and wattage) and are you using any reflective material - mylar etc.

It kind of looks like light burn caused by heat spots. If the mylar has creases or dents etc in it, it can reflect directed light onto the leaves. Heat seems to make it worse.

Took the mylar down last night, reduced the temp, flushed and put 600ppm in the container....and voila! no more goldleaf.

Just a suggestion, im certainly no pro.

p.s think the if ur ppm is a little too high with the sensi stuff it seems to exagerate the burn effect. Kinda like a nute/heat/light burn all in one. Im only using the sensi veg time, and switching to something a little less harsh for flowering. Im guessin you get what you pay for with nutrients.

What is your run-off ph/ec?

WOW...looks like it could be a few things:
nute burn, ph problems, calcium/magnesium def, or temps. If the plain water isnt making a difference, check the ph and temp. If thats ok. i would give it a bit of cal-mag+

Ya ph was dialed 5.9 temps OK. Everything like that the same as prior successful harvests. I have a few plants I'm throwing into the experiments. One has high nutes with cal mag and basiccally all the other variations. It's done this with GH also. It's like someone is poisoning them.

Forgot to check when i dumped all the water out to flush

Ya it looks like the light stresses them but because of the nutrient prob. I have 600's and they were not all that close.
Thanks,.

I had severe light bleaching issues, but they were caused by 'out-gassing' from spray glues I had used in order to attach the f'n Mylar. Have you tried removing a plant from the environment to see if it improves? You can also just use 2 new clones in soil, one in one out, make sure they get the same food.
Mine were bleached to shit even though my temps were a perfect 78 at canopy level, but it was due to poisoning, so they were not able to handle the light anymore, I mean like any light
Good luck,

That is very interesting. I wonder. i may check that. It seems to be related directly to bloom nutrients. Everytime I up the nutes and or change to bloom, any brand, they do this. Hmmm something in the air not compatable with what goes in the water? I'll ponder and look around for possible toxins.

reposting - new revelation - thanks please see re-post

I had a BUDdy that had a shop under a freeway. He never had a good harvest until he moved. I don't think I have any toxins though. maybe just me. I had tried to experiment and overdose plants. They only get better. I guess deficiency is what it may be rather than lockout. Thanks for the input

I think you may have something there. After everything went fuk fuk I took a few aside and tried to overdose them and included good amounts of CalMg. They only got better and I'm almost ready to dose the whole crew again. i didn't think that when I get a problem I should add more stuff. If I did use cal mag to try to correct it would always be in a mild solution. but it seems the plants are really craving the food I deny them when they freak out. Would mag deficiency be this bad?

Hmm, Here I am again SOS but with another potential problem noticed. i have found a can of leaking stain and other cans of paint and shit I'm storing for my dad in law. All in the same building. He's a painter. I think i'm going to store it all away from the building. Do you have any more info on airborne toxins? Are you confirming that your glues caused those leafs to fry? That's what my harvests look like!
