Our plants have been in the flowering stage for a while. Recently the sun leaves are all dying and turning brown. What is causing this? We recently sprayed for spiders and have been using the correct pH level and a bloom firtilizer.

organic spray really doesn't tell me much

How soon after you sprayed them did they turn brown?

So it's possible you sprayed with the lights on and cooked the fan leaves?

Sorry that happened, recommend always spraying right before lights out

Spray during lights on is probably what did it. Pyrethrin is highly phytotoxic under lights. Only ever use it in the dark.

For spider mites try a homemade spray using rosemary oil, peppermint oil, and garlic oil. Lots of recipes on the internet for homemade rosemary oil spray. It has shown promise killing two spotted mites. You can also try using a sacrificial plant, essentially treat all the plants except for one and then crowd the infected/treated plants around it so they are all touching for a few days, the surviving mites will theoretically migrate to the untreated plant. Then you throw it away, and treat your kept plants again. Apply the spray every 3-5 days for 2-3 weeks.

Alternately sulphur also works well to repel mites, either wettable or vaporized, just know you can never apply sulphur and oils within 3 weeks of each other or itll damn near kill the plant.

White oil? Do you mind elaborating on what that is? I've never heard of it but I'm always looking to add tools to my toolbox...
