Hello,
can you give me some advice? On my flower, the top leaves are light green to yellow in the middle. Some have bright green tips. The other leaves are normal. Do you think it could be the light? From what I've looked at pictures online, the light burn starts from the edges and progresses inwards. I have a 150w LED light about 15cm from the tops of the plants. The manufacturer recommends a distance of 15-40 cm from the tops of the plants for this light, without specifying individual wattages. However, when I tried placing it higher up, it didn't seem to have any effect. Or is it normal for new leaves to be bright green to yellow like this? They usually turn green later.
