As Love? says, if you can't use a bigger pot then you really have to take care of your feeding schedule because the excess root mass is now depending on YOU.
Hi! me again! Having problems with "clawing" of the leaves. Is this just cause she's root-bound? Been giving her 2ml grow and 4ml bloom every watering, every three days.
Been giving them 2ml biobizz grow and 4ml bloom for every litre water the last waterings.
Do you think they need even more?
It's 4 weeks in flower today, and 5 1/2 week since switch to 12/12
Are you letting that medium completely dry up before watering? Do you have drainage holes? It sure does look like a N def. possibly caused by ph issue.
