Purple Haze

31/01 - I made a small organization in the grow tent and installed a dimmer on the lights to reduce their power, consequently lowering the heat I was experiencing and adjusting their height to achieve a satisfactory PPFD (using the Photone app on an Android phone). A top pruning and a little defoliation was also done on the plant. 03/02 - Some leaves are showing small burnt spots and slight curling. What could be the cause? I'm currently dealing with Fungus Gnats in the grow. I applied a combination of Beauveria bassiana, Metarhizium anisopliae e Isaria fumorosea and covered the soil with burnt rice husk. I’ll wait for the soil to dry and then use hydrogen peroxide to try eliminate some of the eggs. I noticed that the type of fabric I used (raw cotton) to make the pots was effective in allowing water to escape from the soil, but it started to rot at the bottom and disintegrate. This has become an entry point for Fungus Gnats, and I saw some white 'worms' coming out from underneath the pot (a terrible choice of fabric for the pot; I only used it because I had several meters available at home). I will transplant to felt fabric pots, which are synthetic and see what happens.
