could anyone help me

its been going on for a bit now my leaves are turning yellow i was just wondering if anyone could help me with what it is thanks for any feedback

Could be a number of things. Are you in flower? what setup are you in hydro or soil? What is ph at? What nutes and at what strength or ppms are you using? Pics?

More info needed ..Pictures would be a plus

i am in flower been in 5 weeks and im using 2x 600w hps on 8 plants the jellow has only started from the flower and im using soil canna if uve heard of it its good quality in england

Your plants will turn yellow in flower, they are using the nutrients up in there leaves to help produce the bud.

Usually not this early in flower though, is it alot of the leaves or just a few fan leaves? If it is just a few leaves than it could be natural for a 8-10 week flower strain, i still think 5 weeks is to early to be nitrogen deficeint

FAQ has a diagnostic plant problem section with great pics.......2nd item from bottom..
