Wow this growing stuff is hard. Just as you get a solution for one problem , up pops another. I’ve been told I have about a month to go on these organic outdoor plants. I live in Spain and it rained and last week and then it was quite humid. I thought I’d managed to get them out of the rain but I just noticed this growing on the top of the buds, Could it be bud rot? I took off 5 green caterpillars a couple of days ago and I’m checking daily. The leaves are super green around the brown bud and from my research it says the leaves go yellow. What should I do please ? I have seen a random white fly but nothing else. One of The other plantS has a couple of small leaves twisting but they are still super green.
