I had an advice from an old friend: just let them grow. and i nearly did exactly that. i just tried out a little bit LST on the Strawberry Gorilla and Northern Lights. Afterwards i cutted the big leaves that were responsible for Shadow and low airflow and watered them with less water, but all 2 days. lets see how they react. talking about nutrition: they just got a little help for the bloom and wont get anything before next week or until they show some deficits. i think it wasnt the cold weather that let my SG suffer so much, i just overfeeded her.
