Should I harvest the top buds and leave the rest?

hi everyone
I have a blackberry autoflower from fastbuds
Its at week 10 Iam going to start flushing from tomorrow, currently using a Mars Hydro 600watts(260 true watts) going to switch tomorrow to a 600watts hps
The top buds losing smell and look ready but the bottom ones air airy and still have a lot of pistils so I was wondering If I can give it a flush leave it under the 600 watts for a week till week 11 chop the top buds that are ready and leave the rest for an extra week then chop the lady down what do you guys think

These are the pics!

Check the trichomes first. But you probably need to let it go longer.

What happened to all the leaves?​

I got rid of a lot of leaves lately to increase light penetration did I mess it up?

That's debatable. I'm of the opinion that the leaves are the engines of the plant. That's where photosynthesis takes place. So I never cut a single leaf. Buds still grow and get dense even when covered by leaves.

What kind of magnifier will I need some say a x30 or a 60x and higher what do you think?

Yes, it is fine to take off the tops

Thanks!!

I mean when they are ready, but it is fine to take ripe flowers and leave others for later

Your light couldn't penetrate to the bottom of that small plant? It sounds like you needed the 600 hps weeks ago.

Will it still make a difference with this plant almost finishing? & I bought the 600 watts because I just noticed the mars hydro was weak

Unfortunately I don't think the 600 will make a difference now They look very close to done to me. The 600 will make a nice difference on your next grow.

Thanks for your reply brother much appreciated!

Depending on the size of the plant it’s absolutely okay to take only the top and let the bottom finish off.

So literally cutting branches off of the plant wont harm it?

If it was early in the plant’s life it would but, the plant is basically completely done and ready to harvest so you’re just waiting on the bottom to catch up and finish maturing. Not much harm can be done as it’s at the absolute tail end. More positive benefits than negative and this is very common in outdoor grows where plants are much larger.
