Hi I am looking for some remedies to help ease the stress of heat stress in outdoor plants. I have been foliar kelp and humid. Also they regularity get compost teas and a silica solution. There is no bugs as I have checked under microscopes and not found any dead or alive or any eggs.
I have not been able to come up with a good reason why my plants are doing this. I have scoured the leaves with a 60x to 100x scope to look for bugs which was my first thought and there is nothing alive or dead or any type of eggs. Does anyone have any thoughts on what this could be if not bugs...
