My .02 You need a bit more Mg, just a tsp of epsom salt top dressed should correct you time release style. If it were burn it would be top down as you correctly stated. Low Mg can cause a lockout but it looks like it's hungry too, I wouldn't back off the nutes before you correct the Mg, you may end up bumping them. Mg can be sprayed as foliar as well if you want quicker results.
Just watered the vegging Blue Dream doms with the 1 tsp of epsom salt per Drs orders. The PK x SAD are less than 2 wks into flower, when they wake up I'll do the same.
