Can any one confirm the problem?

Can any one tell me wat this is please

Looks like light burn to me, what lights you using and how close are they to the plant?

400 hps ther about 12inch away if I move my light higher will the stretch much

Back off the light to 2'. It is way too close at 12", and that is your problem it appears, and no, the plants will not stretch.

Sweet thanks ill move it higher
