Hi again all.
My poor poor mango kush is in trouble again. I have done a google search and being a newbie not sure if she has rust fungus, deficiency/toxicity, light burn or a pest??
I know she had nitrogen issues awhile ago so I cut right back on fertiliser.
She had gnats hanging around a few months ago until I dried out the soil and added a bowl of vinegar dish soap and they have gone.
She is in week 4 -5 of flower and the rust spots started to show about a week ago and they seem to be spreading mainly on the sides of the leaves mainly and some have a slight curl downwards.
Not sure if this is a fungus or crystal. I prefer it be the latter.
A few more through a loupe .
This one is the reason I wonder if it’s a fungus. I read that fungus is raised and not within the leaves.
This is the bottom of the leaf. I hope you can see how it is curling underneath.
Only the brown and green are the leaf the rippled grey is the table it was on.
Strain: Mango Kush
Age: 16 weeks. in flower 4 - 5 weeks.
problems: eaten by strawberry slugs, nitrogen toxicity, split stem, now this :-(.
Medium: 50/50 Coco Perlite. (still has some old soil around the base from when I transplanted.
Feed: ozi magic grow juice monsta bud. recommended dosage once a week.
pH: 5.5 (was 6.5 until last week)
Question: If it is rust fungus is it fixable this late in flower or dangerous to health if smoked? and will any treatment effect taste?
