Red strawberry banana

Hi all. 3 red strawberry banana autos on the go. I decided to repot further into the pot as they grew stringy Again!!! So this may of held them back a little 2 of the 3 are looking good and starting to produce more leaves started with the bio buzz acti-Vera @1ml/litre. Little less then the schedule but seem to be doing ok. And don’t seem to be to far behind other grows. 1 of the plants is growing gradually but seems to have had this issue with orange/yellow areas on the leaves. see picture. This plant has been treated no different to the remaining two just hoping she can bounce back and do ok. Any advice would be much appreciated. Will be ready to start adding a little biobizz bio - grow into the feeds next.
