My plant is about two and half week old and the plant’s leaves have yellow dots. Some have burn tips. Any advice or suggestions ?

Plagron Lightmix is a mix of the very best, carefully selected types of peat. The addition of various types of fibre and perlite results in a lightness and oxygen level found only in Plagron quality substrates. Only a minimal amount of nutrients have been added to Lightmix. This makes Lightmix the perfect substrate to fertilise according to your own judgement and choices. Lightmix produces the highest yields when used with Plagron Terra Grow, Terra Bloom and the additives from Plagron.
