Help! Can this be saved?

Im at day 83 of my second grow.
I'm in soil with an unknown indica strain that is fed a 1/2 strength hydro nutes 3 x then 1 water feed under 1500w lamp with fan blowing over top. I did this for the last grow and went well.
The plantsurgery leaves on the main two cola are shrinking and the tips are dry and look burnt. The smaller colas are ok.
I was thinking I may over fed them as the last one was a lot taller. Or that it got burnt by the light. It's about 16 inches from the top. I did have it closers to the fan and more in a corner for a while the I moved all them round and there was more direct light and not as much fan.
Can I save it of harvest it now?

Also thought I would show the main cola with something to gauge the size

Thanks for the reply.
I have noworked cut it down and is drying.
I used the same feeding cycle as last time but in the first grow they stretched a lot more.
Also last time I harvested the indica at the same time as the sativas at about 90 ish days at it was still looking healthy.
Every grow is a learning how experience.
The sativas are doing really well. About another week or so I think

Hey most ppl chop early i applaud your patience. 83 is long on indica but i had one go that long same damn strain iv always grown which i usuallu take between 65 and 75 but she just woukdnt ripen one round ... make sure you are scoping trichs and not just using an arbitrary day figure. They are cheap and really help u decide an individuals ripeness

I had a loup to check trichs but I've misplaced it. Ordered a new one and just waiting now.
Will use it for the rest of the plants.
It's worked out ok in the end as we have just run out of the last grow. So the some of the indica will be good to puff while waiting for the rest to finish
