Is it ready?

what strain do you have?

i flush three times throughout my crop, for an 8 week strain i would flush for five days with a diluted solution at the start of week two, the start of week 5, and the start of week 8 till harvest.

you would adjust this for a 10 week sativa slightly.

others flush the last week or two before they harvest.

this is why it is good to know the strain you are growing so you know when to flush.

You want to flush during the last 1-2 weeks before you plan on harvesting. As far as knowing when the plants are done you will need to get a microscope(60x+) and check the trichomes. You want around 85% cloudy, 10% amber, and 5% clear(or so I read). A guesswork method would be when most of the hairs recede into the bud and the remaining hairs turn brown/red, but that could happen at any point during flowering. If you don't check the trichs you could easily harvest too soon or too late.

that ain't done from what i can see.,.. how many days flowering? get a scope.. thts really the only way to tell

2nd pic, says 3 weeks anyway, probably more.

Compare to this bud (I only chopped her because I'm out), it could have gone for another 5 - 7 days.

start flush now... you want to wait until those hairs on the top of colas are not white and all bedhead looking.. you still have new pistils all over buds.. not done. looks likes 2 weeks at least. begin flush now

you flush when you have a problem that requires it

Zeus's Take on Harvesting

Thx you all , but I chopped the highest collar already, because most of the leaves turned brown ( like burn dry ).
Not sure Is it dying or lack of nutrients.IMG_1198 copy.jpg
