WWF Marijuana leaves advice

A question from a fellow grower:

Can you please help me. I have planted my WWF, they are three weeks old. I have them under a 400w hps at the moment.
I have noticed some blemishes on the leaves that is worrying me. And they seem to be going yellow.
Any advice would be highly appreciated.

We need more info. What are the parameters in your grow room? I’m thinking it might be the pH?

Let’s get you started with a support ticket, answer all the relevant questions the best you can and we might be able to get an idea of what is going on.
If you do not know, or do not use something, just say so or put ‘NA’.
