1st Grow- NL Auto from Growers Choice

I’ve heard of northern light leaves yellowing and falling off during flowering but these are all turning purple.

i’m not sure if I should harvest these at all the little sacks look all white and not Amber. ?

Nutes- FF trio. Stopped Grow Big a week ago.

When growing mostly Indica hybrids, it is better to harvest your plants when the resin glands are completely developed but not fully ripen - before they turn amber - unless you want to be glued to your sofa.

That's two separate plants right? The first and third pic look like buds that have several weeks left, but the other two look pretty damn close.

I disagree with the above response to harvest but there is a lot of personal preference involved. I like all cloudy with some amber for both indicas and sativas. I also like to wait till most of the hairs have turned orange with most strains.

As for the colors, that will happen with many strains late in their life, especially under LED and CMH lights. There's a whole range of reasons why but it's not necessarily a bad thing. Your buds look great for a first grow! Also, I'm a little jealous, my NL Auto was from Seedsman and didn't look like that till 100 days ... chopped her at 117 and it was probably early.

Autos HATE excess feeds ... FF trio can make FFOF too hot / loaded for a plant looking to finish within 90 days typically.

Next time run FFOF soil alone .... you will see a big difference.
