First Time Grower, When to harvest

So this is my first time growing and I am trying to learn the vast amount of knowledge require to have a successful grow but is there anyone that can help me identify how far away from harvest I am? I have some pictures attached. Any help or advice would be greatly appreciated.

You have a few weeks to go. It's still developing new pistils. How do the trichomes look?

Are you giving them nutes? Which kind and how much and how often?

I am working on getting a better magnifying glass but from what I can see with the one I have is that they don't look amber yet. Maybe a couple of them are starting to change but 98% are clear to cloudy from what I can tell. Hope to get a new glass tonight. I will report back once I can see more. Thanks for the quick response.

Actually I have been watering her with my fish tank water. So I haven't been using any nutrients.

Also the lower fan leaves are all starting to slowly turn yellow and fall off. I know it's normal at the end of flowering to be deprived of nitrogen but do the leaves typically yellow die and fall off? More pics to come shortly.

2 to 3 weeks probably. Don't harvest early or you will be disappointed.

How lomg have they been in flower? If 5 weeks to 6 weeks id really suggest a nice P and K dose for a week. It will make a difference.

Because theyve just had fish water its harder to tell how mature your buds are as they will look wispy due to not enough food. Your plants look to have weeks left. Id almost say 4 weeks give or'take. Here is a bud i cut tonight at 62 days or 9 weeks and it could actually have gone another week...but its a good image of what mature bud looks likeView attachment 2744432
