Just took my girls out of their dark period as I flipped into flower and all tops are yellow

IMO, while yes 48 hours of darkness may induce flowering quicker, it's at the cost of stressing the plant. You're more likely to get herm plants and stunted growth from this than anything. As I said a few posts back, just use a far red EOD treatment if you want flowering to initiate sooner.

I definitely agree with you here. I'll never go longer than 12-24 hours again!

I vote for not changing anything unless the problem gets worse over the next few days.

Youve had 48 hours of growth with no lliight, which means next to no transpiration, which means no nutes. See if it doesnt clear itself up in next few days and go easy on the light levels until you see new healthy growth.

That's exactly what I've done so far and they look to be bouncing back. Also...I think the blurple light was intensifying the yellow. Here's a pic I just took with the white light only 2020_0402_05260400.jpg

There may be real science to back the dark period before flipping - but I never read it, so it's bro-science to me! :bigjoint:
My understanding is that it "resets" the plant, and that helps it respond to flowering a bit faster.

But I use it too - actually, 33 hours on this round (long story on how I ended up at 33 hours...)

I did my dark period 3 days ago - tops turned neon green / yellow.

I panicked and posted here - https://www.rollitup.org/t/neon-growth-tips.1021638/

They came back fine and are looking good! - Hope the same for yours! :D

Thanks man, happy yours bounced back! Looks like mine are almost back to normal. I think the blurple light was really intensifying the yellow too. Here's a pic from just nowIMG_20200626_204716_474.jpg

Hey sorry to hijack your thread but I need to buy nutrients and I was considering the cultivation nation 3 part or two part dry fertilizer. I was wondering if you like them or not

All good! I've recently switched to dry ammendments, but have considered going back to the cultivation nation 3 part. I had a few really good yields with them, but had salt buildups in 50% of the plants which led to some pretty bad lockouts. Nothing to do with the nutes, just my own fault from not watering with enough runoff. Regardless of the lockouts, the affected plants still ended up with some hefty yields and great bud
