Hello I am growing 3 bigbuddah critical mass auto's they are 2 weeks
Into flowering and I am getting yellowing bottom leaves but they are travelling up on one of them
I also have some of what I think is nute burn on one of the plants but it's. Minor problem effecting
2 leaves on only 1 plant pictures below
My setup

1mx1mx2m grow tent
250 watt HPS with reflector
Running at a temp of 27 Celsius
Using bio bizz bloom (since flowering after. 5 days)
I previously used the biobizz grow nutes during the veg state
My dosage is 1 cap to 2L of water stupidly I have only just started ph my water to 6.2
I'm an organic grower growing in soil pictures below of problem

Here are some better photos of problem although I removed some yellow leaves I also took a snap of my setup and top half of plant

I wouldn't worry about the yellow leaves, the plant is pulling nitrogen from them, sending it to buds.

Cheers so all is normal?

They don't look bad to me, what size pots do you have them in? You will get a small yield with a smaller pot, 3 or 5 gallon is ideal for flowering a plant, the bigger the root system, the more nutrients the plant can uptake.

Got them in a 12 litre pot about 4 English gallons

That should be large enough, so now it's just a waiting game, watching those buds swell.

Hell yeah! Haha can't wait for them to start puffing out

Have you thought about starting a grow journal? You will probably get more attention to your plants if you start one, a lot of members don't respond to the faq section.
