HELP! Yellowing leaves

[420Snoop]

There’s been a lot of leaves turning yellow and falling off or being easy to pluck off I gave maybe three feeds since flowering started and I just been giving water mainly. I ran into a little toxicity I think a little bit ago making the leaves curled and I just been giving water since than. Most of all the new grow is good I have leaves actually turning purple but a lot of lower leave are turning yellow and dying is this a problem , do I have a deficiency or toxicity .

How far along are they? It's normal for yellowing to occur in mid to late flower. You'll generally feed up until the final week or so of flower and then just water.

True that what he said ^^ i got a early afternoon buzz and feeling goooooooooood so no worries try and lift the pot sometimes we get lockout issue with irregular waterings. All seems to happen to me near harvest or late flower.

Agree with almost done lookin good. I would start watching the trichomes I think she's close to going into labor

The leaves turning loose easy can be under water. The yellowing and purpling I would not be overly concerned with, as said normal in fall. However those curled leaves can mean root issues (can be over or under water etc.) or bugs, look them over with a 30X zoom lens.

It may be root problems I dont over-water I believe I wait till it’s dry there’s two plants in my one pot you think it’ll be a bad ideas to transplant ?
