Run-off got pretty high on the plants in the main tent when I tested it this week (2300ppm) so I flushed the plants down to around 900 over a few water events with half-strength nutes (~450). I think this, plus (mainly) the plants being too close to the LED caused them to throw some foxtails - particularly the middle plant (although I still think that spindly shit is also partly due to the bag seed pheno). Noob mistake on my end and I didn't realize until it was too late. Now the light is turned down and the run-off is back in a good range. It got high because my auto-watering halos were mostly running off the pots and not sinking in - this is because I filled the pots to the brim with coco (another noob mistake). Looks like I'm hand watering until harvest :)
Big Mumma in the blurple tent on the other hand is still killing it..
Apologies for having to upload videos of the microscope - too hard to hold it still and press the button for photos lol.
I am in Coco at the end of week 5 flower. I am wondering how to time the flush if I'm planning on flushing for 10-14 days before harvest? I have a USB microscope to check tricomes also.
Hi my friend :-) If your trichome heads are about 80% milky and 20% clear you can flush :-) If they are 70% milky and 40% amber you can harvest ๐๐ It looks great bro ๐๐
Thoughts on trimming in flower? I trimmed underneath and lightly defoliated the top about 2 weeks in to flower. I'm mid-way through week 5 now, not sure if I should just leave them or trim some lower larf. Not planning on touching fan leaves until final week before harvest.
Thanks for your help on the flush timing question @MadeInGermany and @Fusion - very helpful indeed.
I'll start putting up photos from the USB microscope in the coming weeks so we can nail this harvest time - I'm excited :D
