Organic SOG yellowing question

I am growing NL and Afghani SOGs in 4 inch Fox Farm soil containers with all the right stuff under 400W.

I have had great past success when flowering at a max height of 14" - 16".

However, I recently allowed a batch to max out to between 21" - 23" in height in the same 4" containers.

Almost the entire batch has yellow fan leaves and looks like the entire lot will have to be yanked before full maturity.

The symptoms appear to be that of nute deficiency with leaf color ranging from very light green to bright yellow with only 1 plant having burnt tips.

Main kola buds are under-developed as well as the lateral buds.

Could excessive plant height for a small 4" container be causing a nute uptake problem???

your roots probobly cannot grow anymore?? they're rootbound

Absoloodle, your 4" pots are strangling your plants, root size equals plant size.

Thanks guys!

Being too tall was the only thing that I could figure out since nothing else has changed in respect to nutes, temp, watering...

This latest batch is back on track with the fat juicy buds!
