bio bizz question

i have biobizz grow and bloom, my plants are yellowing on the lower leaves 30 days into a 55 day flowering. im assuming its nitrogen def, can i mix bio grow and bloom in the same watering due to the higher nitrogen in the grow, as i stopped with the grow when i started the 12/12

Your bloom should have a little bit of nitrogen in it. Shouldn't need to add more nitro, but I'm a nub so wait for a second opinion, haha.

you should be using grow and bloom together... look at the biobizz feeding chart...

it's on their website

You should continue using some nitrogen into flowering, at leaset the first 4 weeks or so, just slowly taper it off. And if you see yellowing after that (unless the plants are in full flower and near harvest) just feed them some grow

do you mix the two in the same watering can?

yes that is fine..

heres the chart.. for example.. if it says 2ml/l bloom 2ml/l grow you put 2ml of each in a litre of water... so you would have 4ml/l total

are your plants tall ? most of mine do this whether in soil or hydro ! old leaves and lack of light plus they could have done their job already.
ive used bio bizz in bio bizz soil and canna soil and its good stuff it really is,i much prefered the bio-bizz nutes over canna nutes.
its got nitrogen in both parts if i remember correctly anyway but more in grow(veg).
i may be wrong as ive not been parenting your babies but if your using the nutes as suggested in the table it cant be lack of N as i found the table a bit too strong at times.
