They look good, but it wouldn't hurt to use some mild IPM like neem oil-5ml/liter water-be sure to add a surfactant like a few drops of dish soap, or even better, get some yucca extract (it has it's own antifungal properties.) An ounce of prevention is worth a pound of cure-per, my grandma. Neem can be used weekly until flowers start forming and is good insurance.
