h202 mix i used was the best spray i used in my view. i used 3% and 450 ml of h202 to 2 gallons of water but you can use straight 3% h202 just costs more without mixing. i would dilute it. wish ya luck man and post any findings or anything you notice. i would add seaweed to water along with fulvic acid. both cheap and very effective. a nitrogen rich compost tea will help but carefull if in stretch or flower
I have a small bottle of 6% so I'll dilute that down and spray tonight.
Already this morning I have pulled off a load of leaves.
So far I have used Bordeaux Mixutre, Neem oil, Garlic concentrate, Hertomyc(L) and Bicarb Soda .
I don't know if any of them has even slowed it down but every morning the blight is on new leaves, the weather isn't helping either, wet and humid for the last 3-4 weeks.
Anyway I'm gonna risk putting up a 12ft x 6 polytunnel and getting them in there, if I don't I'll have mold regardless when they flower.
So I guess I could use a sulphur candle, what are the chances it could burn the plants?
Thanks again and good luck also.
