Hello,

Only the top 10-12" of the plants have got leaves like this.

Am i right?

Yep funnily enough 3/4 of the sharksbreath i've grown have had this but when i read up if this is common in this strain they was no mention, must be the compost which is westlands.

I got seaweed extract with sequestered iron, maxicrop do it and the stuff i've got is called vitax, pretty much the same though.

So thats it thats what iron deficiency looks like I thought that was magnesium

I don't know for sure thats why i'm asking ...

I had an Mag deficiency as well years ago Click to view attachment...

Iron starts at the top and Mg starts at the bottom, I find when iron def first starts it looks like a kind of marble effect then it fades to yellow nearly totally but not quite totally like Mg and they dont tend to drop off either like Mg does.

I found that they perked up after 2-3 feeds with that vitax seaweed extract with added iron.

Yeah I think its Iron deficiency, looks very similar to what I had on my red dragons early flowering, I fed with Maxicrop + Sequested Iron and also used it as a weak foilar spray and that did the job and havnt seen it since

Cheers dudes

I'm seven weeks into flower so not gonna bother spraying just going to suck it and see ,

Think I caused it by letting my PH go to high and locking it out.
