I’m at day 65 and the leaves do not appear to be doing so well. This is my first grow so I’m worried about waiting too long to harvest before I screw up something. Should I wait a few more days/weeks to harvest or should I harvest soon?
Lots of white pistils, which means you’ve got a ways to go. You won’t be disappointed, as the flowers will continue to bulk up.
Your plant is experiencing nitrogen toxicity. It is what is causing the dark leaves and burned edges. @Myfriendis410 will know, or know someone, who can help with how to address nitrogen toxicity in a hydro grow. I’m interested in knowing as well.
This is entirely marketing and light is inadequate (by far) from properly flowering out the plant.
Your plant shown is not very far along in flower and again, without knowing what the plant had been exposed to it’s not possible to diagnose. Plant should not be on distilled water yet IMO. Leaves are burned and will not recover. Along with plant being in flower you won’t get much if any new leaf growth.
I would discontinue the CO2 as it’s not doing nor going to do anything, sorry.
