The photo you've uploaded doesn't show burnt leaf tips, but it does show brown splodges on your leaves. I would guess that it's a potassium deficiency and/or PH lock out. Could also be heat/air flow issues or pests in the garden (such as broadmites - although they usually leave very distinctive leaf warps behind). I'd check the PH first and foremost.

Yellowing on leaves tips. Should I start feeding her?Some yellowing appeared on the leaves this last day. Temps and humidity are controlled and ok. I haven't been feeding her, she has been growing on light mix for the past 25 days. Im thinking its time to start applying some nutes. Or could be something else? Thanks!
