Leaves' tips drying out

hweixdstarted grow question 3y ago

What I am concerned about is the light. I ordered a MARS TS100 but until it arrives, with my current light, I manage to pull 3.2 DLI but at the range of 20cm. Is that too close?

I usually give my seedlings around 10-15 DLI so I don't think it's light burn. If it's LED 20cm should be more than far enough. Make sure you have high humidity, germinating/seedlings like around 65-70% RH and temps around 26-27°C. Don't water too much, at this stage the plants drink from the leaves quite a bit as the roots are developing. Side note, you should get a diary going, the community can give better help.if.you give us more info 🙂
