First ever grow of autos, how much longer?

This is a seed from ethos genetics called Bello y Dulce.

This is just 1 of my 5 sutos im growing, its around 82 days old right now since jan 18 when they pop above their rw cubes, (im also doing this in rdwc or just dwc (airstones)), here recently i felt they had been in lockout for awhile since i thought they wasnt growing as fast, i never “flushed” them at all from seed to flower( i did drain to waste and started a new res every week) which i thought would be fine but i heard of salt buildup on roots and stuff. So after like 8 weeks i finally swapped them out 1 day before res day with plain un phd tap with stones and a few drops h202 at 3% in there and let them bubble overnight (because previously the buckets they sat in was empty since i didnt wanna move/waste that much water),and the following day i will give them what i feel they need. My question if does she look close to being done? My other 4 are not so big as her flowers are and i feel need way more time, also last feeding i dwitched to the lucas formula at around half of 8ml micro/gal 16ml bloom/gal at 3 gal in each bucket, i halfed it and started to notice a tip burn on most plants new growth, what could this be? A toxicity issue?

Im using General Hydroponics flora trio (last week switched to just micro and bloom, should i switch back to all three bottles?)

TDS/PPM Scale im working in is 500 scale

As far as trichome checking im sol for a jewelers loop, i have a s23 ultra, funny enough i can kinda see them and some white heads if i keep my phone still lol, any other methods for checking when its ripe?

Much thanks guys.

Can’t really tell by the picture but autos are typically done in 10-14 weeks. Awesome frosty buds. Congratulations on your grow. This is what I had to buy due to not being able to hold still. They offer awesome close pictures. About $30. I put mine on a microphone stand

I like my Trichomes to be cloudy with about 10-15% amber

When I did my first autoflowers I felt the same as you. Now I know now that the autoflower that I have I growing for 16-17 weeks total. A digital microscope like the guy above me showed you will be your determination. I like mine cloudy with bursts of tan LOL :broccoli: good luck

You want nearly all those white hairs to turn brown and recede back into the calyx’s then start checking trichomes for cloudy to amber
