Soil/medium: canna terra professional
Grown outside
Avg temps:28-33 C
Strain:alien lights og auto

I had nutrient burn or something i thought was nute burn(god damn seasol) on first few leaves and stopped feeding/did a full flush its now beggining flower as its an auto so i gave ot yates thrive flower&fruit at 1/4 recommended strength(only 1 feed so far 3 days ago)so ive removed the first few leaves my concerns are
1.whats causing the white on the leaves
2.why the leaves are curling/changing
3.whats the white specks on leaf(thoughy it might be mites but ive already sprayed it 2 times now using eco oil to no affect
4.how to avoid this in future
Is my first grow so any help/opinions are appreciated

all is fine mane .. just a small ancient scar
just prepapre yourself to feed her a bit because she will probably lack a bit of fertilizer after stretch .. try to avoid premature senescence

White specks, not positive but it could be the very beginning of thrip damage, definitely should get some yellow sticky traps out to see whats present.

Your sure those are going into flower ?

Thanks ill get some tomorrow when shops reopen

Well its 6 weeks old tomorrow and an auto fem 100% sure its in transition/ beggining of flowering

that does look like thrip or miner damage, not much to do if they're starting to flower. the yellow sticky traps attract them, about all you can do really.
