How they looking =) need advice on clones and flowering space

This is my first grow , have a seperate cupboard which i veg in , Plantes 5 lemon budd seedlings and taken some cuttings from big bomb bomb seeds
Flowering plants are getting to near the light should i trim them or put a screen on top to keep them down?
What is happening to my clones first time . Planted in rockwool with clone gel . Have a areoponics ( diy) setup as soon as the roots show through

if your flowering plants is growing to close to the light and you cant lower your plants of get your light up ..
you schould tie em down .. dont trim em please ..
