Help! Leaves getting green spots!

[mmstickybuds]

Hi

I really need some help figuring out what's going on with my Auto-Bomb lady.
Basic breakdown...
She is 6 weeks old today, been flowering about a week and a half..in an Autopot Hydroponic system and feeding BioBizz organic nutes, had early nute burn and got yellowed leaf tips but then was doing well. She had been a bit droopy the last few days I think due to high temps during the midday heat, I have now noticed that one leaf started getting weird patches of lighter green, they have now gotten even lighter and spread a bit. Really worrying me as she had no signs of any problems like this so far, and since yesterday morning she had these new patches. They look like pretty big spots, about a half a cm or less and they are just a lighter green..so it's like they are turning yellow but haven't yet.
I have only fed her twice since flowering once on Sat and once last night and have used less than the recommended as I get her used to it.

Please help I really don't understand this...I have tried the self-diagnosis but can't put my finger on the problem. Also will upload pics later as my camera is busy charging.

Thanks in advance!

nute burn is rare with bizz but the first week of flower sometimes they use more mg than the bizz can provide this normally shows on the lower growth as the mg is shifted to budding sites this is my guess without a pic
how much are you feeding in soiless you want 2ml grow per litre and 1-2mls per litre of bloom at this stage
also bizz is only good for 48 hours in the res before it needs changing bizz is not great for hydro organic

pics!

Hey all, thanks for the interest...
Here are a few pics, the tip on the one was already dry from the initial nute burn. It may be a little difficult to see in these pics but I think you can get the idea of what the problem is. The other pic will show the drooping I mentioned.
My temps are at 32c/90f..


So Agito should I not be using BioBizz nutes at all? So far both feedings I have given exactly as you have said here. She still growing pretty well and her bud is filling out.

Thanks for this Agito!I think you may be right as the very first set of single leaves that came up have gone basically white. All other leaves seem fine except for the ones in the pics I posted..
I don't put the nutes in the res cos it will clog so I have to apply on the medium, and yeah I have fed her exactly as you said since you gave me the info...

Thanks Kudo for stopping in, pics are there..as I say she is still budding nicely so maybe it is mg def as Agito says...

if the new growth is effected it may also be linked to light scorch

I moved the light higher up as I was worried about this. My main thought was that it was either heat-stress or some kind of nute def that I don't yet know.
The new growth is looking healthy no real dis-colouration, the light is about 65 centimeters above the plant now.

long as you can not feel the heat on the back of your hand 2ft may be to much for most lights
