when do leaves yellow?

dopechess · Sep 25, 2016

I got about 3 weeks left to my white cookies grow and my plant still looks pretty green. When do the leaves turn yellow? Can you have a mostly green leaf plant at harvest??

i've been only feeding her FF big bloom and tiger bloom since flowering with some cal/mag and liquid karma.

Yes depending on strain and nutes fed.. not all plants feed on their reserves if other nutes are available...

As long as she has lots of nitrogen she won't turn yellow.

ok.. so yellowing leaves can't really be used as a harvest indicator.

You want to keep them green until harvest, add a little N as needed.

Nope, that depriving of nutrients, calcium alone is needed for cell development, do you want to stop this vital process at the most vital time of the plants life? all old wives tales just like nailing the trunk with a rusty nail lol

Leaf discoloration usually only happens if there's a deficiency or an over abundance of some sort. The only other time a leaf should yellow. Is if it has died. And the plant is ready to discard it.

Nice one "Nugs"!

I'll add that around here, yellowing tends to happen from too much P/K too early and it's P tox time!

When I ran synthetics. I never went to "bloom" foods till week 3 after the lighting change, and then I mixed them 50/50 with veg and at week 4 - went 100% bloom foods.

This a few days before chopping. 67 days from flip. I cut out all nutes and water only last 2 weeks. Always perfect end to a great grow. There are 6 strains in the pic and on the side

Nicely Done!!

Thank you

If I don't feed heavily, ALL my plants look like this at week 5. So I feed, water, feed, water. My feeds are 1480ppm.

Not really. Yes they do TEND to lose their green at the end but I've seen a lot of grows where the leaves were green all the way til the chop.

DemonTrich · Sep 27, 2016

Yup, keep feeding nutes and you'll have green leaves all the way to harvest.

I take it this is better way than to let the nutrients deplete and have the leaves turn yellow? Anyone done any comparison between feeding all the way to the end and stopping feeding about a few weeks before harvest?

This being discussed in the fade or not thread.

when do leaves yellow?
