First grow need help when to harvest..

[Turpy]

my first indoor grow and my first auto flower grow the strains are 3 bears OG & Sour Crack x Forum stomper I started them from seed just a few days before November started I ran into a problem the other day I think some water I used to water them ended up having something toxic in it and I tried flushing right after and I’ve been making sure that they get perfect water now the last two days but the leaves have died off so much I’m not to sure what I should do about it but I’m carrying on but anyone help me about when to harvest..?

As for the other plant that is way behind I wasn’t able to transplant it until long after and it has a main cola but it doesn’t seem to be keeping up with all the other branches should I cut off those leaves blocking it now or should I wait a little longer the other busy plant i recently cut out a bunch of leaves cause it wasn’t able to get any air flow in between the buds and was almost kind of damp but the ones that are nearing the end do you think I should stop feeding them and start giving them only water..?

Some go water only at the end, I don't. I feed my girls till the chop.

As to the recent problem, I doubt that you were dealing with toxicity, more likely a screwup in mixing your nutes. Don't feel bac, we have all done it. Once the girls are back on nutes at the correct EC/PPM and pH, they will be fine. Overall, your grow looks good, and you are headed for a nice harvest.

As to when to harvest, perhaps you know this, but the trichs are your best indicator. More amber = more sedative, less amber = more racy, generally speaking. However some autos seem to not amber well and risk late harvest if you chase ambering too long. Judging from the pistils, I'd say you have at least a week or two to go, but absent trich pics, I can't be more helpful than that.

You need pretty high magnification to check trich color. There are several ways of getting that, but all suffer from the need for the magnifier device to be held steady to reduce image shake.

Good luck with it.

Thanks a lot man I just wanted to see what everyone else things today is day 62 since they popped out of the ground I don’t have a jewelers eye just yet the sour crack x forum stomper looks like it’s getting close that’s the one in the front right and the second oldest plant..

I don't start checking trichomes till least 50% of the hairs have darkened on the entire plant

This is the only one that looks like it might be getting close I zoomed in as far as I could I don’t have a jewelers eye right now and am pretty broke just wanted to share to get anyone else’s opinion from what I read this is supposed to be a pretty fast strain 65-70 days from seed hairs are about 75-85% turned..

I’d wait least a week probably more like 2 its very hard to tell by just looking the buds and hairs through pictures. I like to see the main colas mostly darkened and the lowers will still have around 50-75% white hairs still but hairs aren’t full proof trichomes may be further behind. Most strains go longer then breeders estimates 65-70 is pretty fast and don't see that very often most the time Auto's are 75-90 days. Good rule of thumb to go by when starting out when you think it's ready wait another week
