Place a burner liner around your plant for a couple weeks jist something to prevent the top couple inches drying up too fast, the tiny little taproot can only pull wayer where it can find it, often with the strong light and heat over a long period of 18 hours, between gravity pulling wayer down and evaporation doing its job in the top.cpuple inches often times water can quickly become out of reach, soon as a plant gets to about 10% of its water reserves and still has to photosynthesize she will begin to sacrifice the cooling of the leaves at the edges of margins. She no longer has enough water to cool the entire plant so she picks and chooses the most important parts to cool first. Survival mechanism initiated. Just needs to hold her water in medium for a tiny bit longer and she will be fine.
