Dried Curled Tips on New Growth

Hey everyone, the tips of my blue mystic are drying up/curling, but what's weird is that 99% of the newer leaves are a healthy green, what's causing this??

I just recovered from root rot with the help of Hygrozyme, and I have a well established rootball now so I don't think it's a pythium related issue since the dried curled tips occured AFTER the roots got reestablished.

I run a bubbleponics system; my ph water is 5.6, been vegging for 5 weeks (to make up for a week of pythium), using Foxfarm nutes, hygrozyme, and temps are running at 86 outside 75-80 degrees res (so far hadn't had too much of a big problem with root rot since the hygrozyme is in there. Also using 3 105 watt CFL bulbs and 2 85 watts for about 5 plants (ones a runt) and they are sitting in a 14 gal res.

I have also noticed that some of the newest growth are starting to turn a weird yellow around the edges of the leaves, this is only happening only on a few leaves

i've diluted the solution, I'm just starting to flower and i think a full dose of flowering nutes is too much Nitrogen for the plant at this stage... what do you think?
 
Looks like it could be nute burn. Do a res swap, recalibrate your ph meter and make sure your close to 5.8 so you know nothing is locked out. Cannabis generally uses a lot of nitrogen and magnesium during the first few weeks of flower. Do you have a ppm meter? Depending on if your growing a sativa or indica, your ppm should be anywhere between 850 to 1100.
 
could be a nute burn , but IMO nute burns are alittle more brown on the tips and effects allover leafs, Klyftonic is it just on your top leaves or have the bottom ones got the burn to ? if its just the top leaves and the yellow starts spreading i would say its iron/zinc deff and get your hands on some trace elements ASAP
