Leaves turning purple in early flower?

Hi guys I've got a blue dream from ilgm seeds. The middle of the scrog got a small amount of light bleaching about a week ago. They werent dead just slightly less green than the outskirts of the canopy.

Today I checked and quite a few leaves, mainly ones in the middle are turning purple. Lights flipped 1/7, started flowering 1/25. So I haven't quite hit the second week of flower yet. Anything to worry about here?

Growing in ffof soil in 5 gal pot.
Fox farm nutes, with calmag and molasses
Temp lights on 75-80 lights off 62-70
Humidity lights on 40% lights off 60%

Thinking, hoping, it's genetics. It's been growing great and buds are steady getting bigger. Thanks for any responses.

Looks like genetics but in general they look n hungry, because they depleated the n in the streach and with so many tops they use a lot of n in that process., I will up your n feedings

I actually fed right before I took that pic. Last feed I had cut out the grow big, added 1 tsp of that back into the mix. Was 1 tsp grow big,1 tsp calmag, 2 tsp big bloom, 2 tsp tiger bloom.

I was reading around and came across that. If it is phosphor I up'd my feed today so that should clear it up if it's a deficiency. Guess I'll know tomorrow

Very easy to spot for me, I let one plant starve with no nutrients (only water) and it showed this deficiency. Leaves will stay purple but it will stop spreading (using a regular flowering nutrient solution).

Feed veg nutes up to week 2-3 of flowering then switch to bloom.
Looks like N deficiency, if you dont do anything now they wont have enough healthy fan leaves late in bloom and you MIGHT not get as good a yield

It's spreading rapidly. Was only inner leaves this morning, leaves on the outskirts of the scrog were still green, they all have a slight purple tint now. Fed it around 2pm today will just have to wait for tomorrow and see what happens.

Did the colors start when you added the bloom and tiger bloom?

Big bloom has been used the entire grow, it's microbes and what not 0-.5-.4. I added the tiger bloom 1/14, 7 days after flipping the lights at .5 tsp per gallon. Fed veg nutes until 1/21, started flowering the 25h. Just been tiger bloom since 1/28. Just noticed the colors today.

On the next run warm up your room temps at lights off and see if it purples. My Blackjack loves to throw deep almost black purples in low 60's... whereas not a sign of it at 68-72F at night.
