too much, too little nutes?

[steelydan]

I am in Biobizz all mix and using 2mil biogrow+ 1mil biobloom per litre. This morning i noticed that a couple of more fan leaves at the bottom are going yellow, the pics are from yesterday.
any ideas? this is day 50

I checked the cervantes book pictures of leaves and to my mind it could be anyone of several things.
cheers

Yeah they'll be a bit hungry.. on day 50 they should be on around 1.5ml Grow & 4ml Bloom. the def on the leaves will more than likely be a result of under feeding.
