Week 7 flower? Ready?

Hi,
I have 3 autoflowers growing in coca.
1 is a purple lemonade and the other 2 are F1 titan and F1 medusa.
1 of them has never really taken much feed and is a little small.(still buds on it though )
I thought I had 1-2 weeks left but now I'm not so sure.
I have tried for the life of me to see the colour of the trichomes but I just can't seem to zoom in enough and I've bought various microscopes and tried using my phone but nope.
How long do the experts think is left if the photos are good enough please?

I just look at white hairs, if none its done. Its foxtailing at the topnof one bud tho which will just keep going on. 9-10 wks is a good time to run a fast running flowering plant. While some report 6.5 wks or 7 or 8 its possible. With certain conditions my pheno I ran for over a year finished ok in 8 wks but had at least some whites. It was close enough for me tho.

I had to look hard for those whites tho so thats a good sign its close. I cant see them in pics that good tho and have chopped too early before but last time I just stopped and waited another week. Made the same mistake and waited another week lol that was a tought one. It was done shortly after that tho in just days. Sometimes you dont notice its premature until you chop a cola.

Youll get a feel for it and call it yourself. Not gonna lie they sort of have that molded look I hope Im wrong but just look inside the colas. One spot looks like it was pruned but could of been just a leaf removal. Whats the humidity? You got good air flow in there?

In short if hairs are orange to me its done but you can take it further and wait for amber if you want that. Genetics matter it may not amber easy or might be plenty amber if you dont want that and theres just clearly only a few white hairs left its ok to cut. If too many the plant is clearly still growing and your losing mass and complete flavor profile and medicine.

Hi,
Thanks for the reply...
I hope there isn't any mould in there
I've been keeping them temps in daytime to around 26-27 degrees and humidity at 50-60...vpd at or around 1.5 does that sound right? I have taken a few leaves off recently as they were yellowing.

Nighttime temp is around 20-23 degrees and about 60 humidity

Temps sound good but rh I like to have as low as possible if colas are fat enough to mold so 33rh to 45rh. If it passes 45 I try to increase air flow on my box fan and anything else to reduce rh so its not beyond that for long if it does then Id say that pushing just past what your setup can handle. Like now Im hitting 50rh briefly every day.

I defoliate and roll open the duct ports next to the intake vents of tents making additional 6” intake vents. Instead of for example, one big frigidaire 35 pint dehumidifier I use two smaller 22 pint dehumidifiers to spread out. Or else there are humid bubbles in the room the tents are in. I set exaust fan/carbon filter on max.

Thats if your yielding a few pounds tho if it just this 3x3 it looks like, just a canopy fan and dehumidifer should keep it good as is. Dont over pack it or rh will get too high. The risk increases past 45rh. With no canopy fans I had mold at 50-55rh.

Just a consideration if you double or triple your size of grow or push it too hard. Its addicting and didnt stop until I had no more available electricity and space to use. You start off lucky but once you get mold it can come back easier if its not corrected with fans and dehueys. People gone years without mold but I got it immediately both budrot and powdery mildew.

Its really my portable ac it reduces my setups capacity. I turned the temp up a bit so its not producing rh spikes as much randomly. Idk why it does but its helping but yea Im over in rh a little in some tents. If I turned it off my rh in those tents would drop to managable conditions but now its too hot. Its a seasonal thing I deal with.
