Burmeseanswered grow question 4 years ago Hey friend,If you are using good potting soil,your problem could be due to light burn.I think 16inches distance from light is alittle bit close to a plant at this age.If your plant is not stretching, how about you raise your light to a height about 24inches and look how she responds.Also your tent temp 29C is hot for young plant and got heat stress.Increase circulation and try to cool down the temp also.Happy growing... ✌️
