When should I harvest?

dont chop it until its truly dead! (worst case itll end up dying and drying itself in the soil probably)

run it till she dies, and just keep flushing her until theres signs of life!

When I flushed, I also took a look at the roots... they look a little different than I'm used to... Is algae my problem?

Ok, so I flushed her until she looked a bit healthier, then the next day added 1/2 strength nutes. She still looks like someone put her in an oven, but at least the trichs are making themselves more pronounced. Hopefully she'll start doing better soon.

I'm hoping it isn't the lighting, but those roots don't look normal to me. Are they slimy?

I wouldnt say theyre slimy... but they are wet, obviously. Theres nothing that comes off of them at least like residue or anything like that. And also it might be the fact that the photo is real blurry.

Those white clumps don't look normal to me, is it just an E&F setup? I had some whiteish stuff growing from some bad slime build up and they looked sorta like your plants above ground. Do you have standing water in your bins? Do you use H2O2? I'm only at the end of my second flower/3rd veg so I'm not a huge wealth of info yet, but I can try to help you out.

You should fill out the form and you'll probably get more answers from the vets. Worthless posts asking "What is your temp/ppm/system/nutes" etc. are what filling out the form eliminates.

OHHHH I should have mentioned. those white clumps are just perlite pieces that fell through my pots

sorry

Quick question: is your flowering plant in the same reservoir and lighting schedule as the seedlings?

for now, yeah they are in the same res. I did that as an extra measure against burn. All priority is being given to the adult (nutes and light schedule). the seedlings were just getting tooooo big for their rockwool, so I took the ones with the most developed roots and just put them in the tub

I figured that the more plants in there, the better use the nutes would be put to, and I might have to fill the res more often, but at least my one flowering plant isnt sitting in stagnant over nuted water for so long
