COCO COIR Bubba Kush Hydro Coco F34 - is that K def or light burn? Molybdenum?

Hey there GWE, hope your Mondays are blessed so far

Got home after a few days away and boy what a difference a week makes!
These are 2x Seedsman Bubba Kush from Seed, topped twice and (badly and therefore not really) ScrOG'd running the full Canna range in 5 gal Autopots.
I've been following the 'normal' feeding schedule, upped from light since these girls were hungry. For the last week, I've also given them a 1/10 dose of PK13/14 as leaves were showing some def.

Wonder if anyone could please help me with the following?
  1. Is this K deficiency or light burn?
  2. The pink/purple tint confuses me a little as this looks like Molubdenum from the GWE def guide and appears on a few leaves?
  3. Would a bit of yellowing like this at this time be normal since it's week 5 of flowering and they'd need PK13/14 anyway?
Otherwise, I think the canopies look healthy and they're getting frosty - I cannot believe how good they look and it's thanks to the community for helping me out so much.
Can't wait for harvest but we're about 3/4 weeks off from the stated flowering time... plus 2 weeks :p

Cheers GWE :)
 
To be honest i think it's a normal look towards later flowering going on with the leaf. Correct the do need the PK more now. Mine is PK10/5 but you should still be fine at that level.
 
Thanks for chiming in SoOrbudgal
I'm worried because I didn't expect the leaves to start getting this way so quickly especially with another 3/4 weeks to go! If you're saying it's all good then I'll go with that :)
