Phosphorus deficiency?

Day 40 of 12-12

growing in soil with 3gal pots and philizon 1000w led 120w(at the wall) @6” from top of buds in a 2x2x4 tent. with 2 part jungle juice Bloom with some big bud, b2, cal mag, an some Alaskan liquid kelp. Temps are 75 lights out and 79-81 lights on with steady 40% humidity. I use a water feed water feed schedule an try to stay between 6.4-6.6 ph and around 900-1000ppm. I think that about covers everything so I had one leave show up with the spots about 2wks ago or so an I just cut away the bad part an seemed to be ok. Then I noticed a hint of purple on top new leaves..thought it was cool not a problem..oops..then literally the past 2-3 days it’s purpling bad an now the purple leaves are getting spots too..should I start with a flush? I haven’t done a good flush since the flip. Thanks For checking it out an appreciate any input.

Mostly what I’m seeing is normal fade. Flowers look fine.

Nice looking ladies.
These look like really healthy plants.
I'd be too afraid to start tinkering with them myself.
Keep doing what you've been doing

Thanks guys, the brown spots an them dying off is normal? First time I got them to purple up..could be strain as I don’t know it. I’ll take your guys advice an just keep them going for now. Thanks for checking it out.

I think they will be fine.

Sorry to hijack your thread but I too have deep purpling of my leaves. White Widow auto been flowering for 4 weeks. The plant is a real beast and growing like crazy. I am inclined to think it’s normal but I have grown this strain b4 and this is a first. Any opinions appreciated. Thanks.

Usually low temps bring out the colors.

A lot of mine are getting dead spots then shriveling up and dying off. The spots are spreading faster now too. I think im’a clean my hoses and water pump on my auto drip feed with alcohol an see if that helps.

I feel your anxiety.....
I'm mid way through flower and the later it goes, it seems harder to hold the line.
These 4 I'm raising right now have been a finicky bunch right from sprout.
Seeing you talk about dead spots, I'm looking at mine and seeing concentrated spotting on some of the leaves.
Not sure what to make of mine or yours.
You're a week ahead of me, but I can foresee the same concerns you're having.
I'm thinking mine is a PH issue (of course), and I'm going to try corrective action next feed.
Have you elimitated that possibility as the trigger?

I haven’t been able to test run off but I always try to have ph for water/nutes at 6.4-6.6. Tomorrow I’ll be able to test run off an see what the soil is looking like.

I know nothing about soil but I know testing runoff in coco is a useless en devour.
Make sure your PH is where you want it going in
