Please help me figure out what's wrong!

The girls are 62 days into flower and just about done. Indoor grow in soil, Earth Juice lineup with some additives (kelp/humis Vitamin B Amino acid cal/mag potassium silica and molasses. Everything looks great, buds are slammed with Trichomes very frosty and the smell is off the charts, crop is Blue Dream and Afgooey Both exhibiting same leaf colors but the Blu Dream is much more. Last week I noticed a few leaves getting dark purple and remaining green in the veins. Problem has gotten worse. Looks like too much phosphorus? Or why about cold temps at lights out? Just afraid I'm not finishing as good as they should. What can I do? Help much appreciated!

The cold could have caused the purplish like you said, it was likely that or just the plant naturally starting to recycle their leaves at the end of the cycle. Is it just some of the older fan leaves? How long do these strains go?

And did you correct your K deficiency already?

they're almost finished, enjoy

I think your right about the temp, it has been cold with lights off. I've been blasting them with bloom and bloom master (earth juice) maximum strength+ doses with PH at 6.5 so I'm pretty sure it's not locked up. Both strains are 56-63 day strains. The discoloration is mostly the upper fan leaves. Thanks for the input. The nugs are super frosty, best crop I've had in a year. Just nervous

Right on. Towards the end I take my co2 off, lower the humidity, and kick my lights down a little dimmer. But besides that, I just keep an eye on the trichomes with a handheld microscope and wait for them all to turn milky. When 30% or so have turned amber, I feed them straight well water for 8-10 days.

Nice to hear it's going well, follow up with some nugs pics if you think of it.

I agree with the temps, some strains are prone to color up when temps drop like that toward harvest, but I've personally never seen a Blue Dream plant do that before. Hope you took cuts! And be sure to post pics of those frosty buds for us! If anything, those pictures just made me curious to see how the buds look

Harvested this morning! So potent that if you're quarter mile from the garage down wind it smells like you ran over a skunk! The colas are oozing resin. Sticky gooey stinky bitches! I'm happier than a pig in shit, wish I could share some with you all. Definitely my bust crop in a long while! Thanks for keeping me on track my brothas!
