Any thoughts on these leaves?

It is only a couple of big bottom leaves on each plant, i gave some cal mag yesterday, hopefully that will sort it. Am using biobizz grow and bloom.

Ian Dury and the block heads , sorry can't give advice on the problem , but I have had it , and I hit it with Cal/ mag and seemed to work , but way more experienced guys will know .

Cheers i did that last night, was checking that it is not something else. Do you give cal mag weekly, every feed ?

hi. sometimes yellow leaves on plant doesnt mean anything. sometimes the plant cant take nutrients from the soil and take it from the leaf. it recommend not to take the leaves out because the plant take it from the leaves. most of the time it happens when the plant reach the flowering stage. upload a full picture of the plant so we can help you.

thank you, i am week 5 using biobizz veg and bloom. I just posted a picture of a different plant, with a different problem, i looked in a book and it might be an iron problem?. I am using those pouch pots and silly me went to flush BUT the water doesn,t flow out! aghh i have a very wet plant! So i cannot get run off to do a ph test?
any tips appreciated.
