So are these plants full of seeds in the buds ? :(

and anything that looks like it could be confused with mold on your end, appears to me to be trics / hairs, which is a good thing..
i didn't really see anything that looks like mold though.. i'd just finish growing them out tbh, like has been said, all of your hard work up till this point will be for naught.

Another month wtf there 7 weeks flower , and not sure which is which strain but all strains I have were quick time of 7-8 weeks . I'll show u a pic of the others see if you think any if them look more done if you don't mind ?

Thanks , I've decided you are right they are not ready and its a shame to chop early so I'll give them one more week an that's it cause this grow has been nightmare after nightmare and just want to see the back of them and try start again . I've learnt loads this grow so hopefully next time it will improve

No, those are not seeds in the buds, they are empty seed pods that have swelled up.

But they have a little round ball inside when I've bust some open

I dont see any mold myself could be just some frosty buds! I would let them go another 4 weeks and make sure you keep a fan on them, sometimes dense nugs can get mold cuz theres not enough air flow. As for flushing it's best done 2 weeks before harvest, you dont want ur plants starving if you leave them for another four weeks as flushing will push the plant to use up all it remaining nute. Ideally you want your temps to be between 75°-85°F and humidity between 40-60%. Also how do you water? You need to wait until your medium (soiless) is dry enough so oxygen can get in there usually a good tell is to atick your finger down to your first knuckle if it's dry it needs water! Also make sure your drainage holes aren't blocked that way water can escape and don't sit there. Great ways to prevent root rot!

Drainage is good , couple are root bound now but I don't over water , they have had 2 flushes now and I'm going to be getting them down next weekend , there is a few ambers now and rest are cloudy. The buds are defo still growing so that's a good sign that there's no seeds apart from just one plant , even though it has yellow bananas in buds they are defo still filling out still so that's good.
I've had a close look just now at the trics with my microscope and there is some ambers , also some are completely orange on top so I'm wondering if its a good idea to cut off the tops which look done and leave the rest till weekend here's some pictures from tonight

Newb here but could it be getting a bit of heat burn at the very top?

It could be to hot on top but it's not dry and crispy like burn
