Light burn
2 fairly new leaves at top (opposite ends) seem to show signs of light burn (yellow tips). They recently turned a bit more green but the tips are still quite yellow. Light = 13 inches away. PAR 370 at center, 350 on sides. DLI=~ 22.5. CO2 bag in tent (at about 620). Thoughts?

Should I put the light on before sprouting or not?
I'm most likely going to be transferring my autos from paper towel into my medium, I've heard some people say have the light on before they sprout and some who say after it's sprout, which is the best thing to do?

Additional lighting in flower???
I’m planning on putting another 2 x 600wLED (blurpul colour type) alongside my current 2 x1000w led Cree cob lights. I have them spare and was hoping this will help with flower/thc production??? Is it worth putting them in or just wasting electricity. Any help appreciated 🤙✌️🎄

DO YOU USE LED DIMMER?
Você usa o dimmer de potência do led? Usa ele em 100% ou aumenta em cada fase (seed, veg, flo)? Tenho visto as duas formas e gostaria de ouvir de amigos mais experientes. Sempre buscando mais saúde para as meninas. ✨🥦
