First Auto grow

Smell has started to come on quite heavy and even the tent walls smell of the blue dream. So far the older blue dream has been my favourite weed smell I’ve grown. Such a delicious fruity smell that just sticks to you, even the leaves smell of it. The white lsd is the tallest of the bunch and is havin a bit of nutrient deficiencies so I gave her bit of a stronger feed with slightly lowered P.H. If anyone could tell me if it’s too heavy or too light of feeding/what nutrients could be the cause. I assumed it was not even nitrogen but I don’t want to give it too much fertiliser incase i stunt or damage my yields. Everyone’s comments are much appreciated and I’d be more than happy to hear your opinions on what I could change and or fix, thanks everyone!
