please help My leaves are yellow ??????

Hi i am new to growing, can anyone please tell me y my leaves have turned yellow :confused: they are in vege stage and have been for 7 weeks i am using Biobizz allmix.
I have attached pics of my sweettooth.

I don't know the answer myself but I'll speed up the process now by asking what nutes are you using and how much? I'll take an uneducated guess (I'm a newb myself so don't go by me) that it's nute burn!

I'll disagree with nute burn. A number of things can cause this symptom, but I'm gonna "guess" overwatering. I don't know how often you are watering, but I can see that the saucers are full of water. If the plant remains wet and soggy, rotting will continue up the plant. I would not water again until the pot gets very light in weight. Good Luck :)

wat kind of light are u using? is the ph the same in every pot?

nice plants, hope u sort it out :)

Hi
Thanks guys for the replies much appreciated :-) i am using a 250 WATT HPS RADIUM RNP-T LR SUPER, High Pressure Sodium Vapour BULB, all the pots are all the same.
I water them every 2 days but haven't watered them today as i was unsure what to do about the leaves.
Will the leaves just die off ??

i had the same problem using almix or should i say have the same problem 4 of my plants are in allmix are yellow on the bottom leaves buy my other 5 plants are in canna coco and are all fine must be the nutes that is in the allmix or the ph of the mix.anyways good luck m8

Yes it must be the allmix which costs more than your garden centre soil so you would expect it to be good, what is canna coco ?? and where do u get it from ?? is it better than allmix ??
thanks.

Hmmm, interesting. I'm using all mix too and the bottom leaves of my 2 week old plants are mildly yellow too. I just took this for a lack of N and started feeding them. Perhaps when it comes to transplanting, I'll use coco.
