I’m not sure what’s causing this but I have multiple plants vegging indoors with this issue. Ask away and I’m happy to provide the answer to any and all questions. Sent from my iPhone using Grasscity Forum
If leaf tips are turning brown and getting crispy the most likely culprit is a phosphorus defiency. I add kelp meal to fix that. Usually a teaspon around drip line and then water in. Whats the soil ph? What light sorce are you using and nutes currently?
It's not just the tips, it's the edges as well. The soil and water is pH strictly to 6.5. I test with a pen and a color chemical tester. For nutrients, I am using a very, very light blend of GH drain to waste schedule. About 1/8 to 1/4 strength and clean water every other watering also pH to 6.5 Lights are two 110 watt CFLs with a color temp of 6500K
