Leaf

hi,, I have noticed that i have damaged one of my leaves while i was puting a cover over them, what do i do with the leaf .Do i just leave it or take it of they are only 3 weeks old.

And also i need some help on my fertz i am usind a weekened newts solution at the moment but the roots are starting to come out of the rockwool is time to raise my fertz.

just see how the leaf goes if it goes brown n dies get rid of it ...if most of the leaf is healthy leave it .

I agree with the sativa high for the most part but....... too much damage will lead to the plants efforts being directed between growth and repair as opposed to growth alone. If your plant is healthy overall and you're comfortable that the damage isn't too severe, leave it on. If the damage is relatively substantial, take it off.
