Deficiency?

What would cause this, running DWC with advanced nutrients (jungle juice) exactly to the chart.
6.1 ph
Veg for the last 6 weeks

Are you flushing/Have you flushed them? When I used AN (some years back), I found them way too strong and had continual issues with nute burn and nute lockout. I agree with nose: let's see the roots. AND GIVE THEM A GOOD 24 HOUR FLUSH, and try lowering the nutes.

Howdy webanator. What are the water and air temperatures? Also are the reservoirs (planters, buckets, or totes well aeriated and all of the possible light leaks (no clear tubing or uncovered holes in the lids or covers)? Have You been changing out the nutrient mix regularly and topping off (at mid-week with pH'ed water? And the 'big' question, is there a musty smell in the reservoirs? Root rot (brown algae) can cause many problems for the plants that can resemble various nutrient deficiencies. I try to keep the water temperature between 61° F and below 70° F, and the air temperature should be kept below 85° F.
Good luck with Your grow.

I’d say light burn.

I agree with DW2! I don't know your environment factors, so it's hard to say... but if all is as it should be; then I'd say they're suffering from a Calcium and Magnesium deficiency. Use CalMag or MagNiCal from Remo; there's a whole bunch... but in saying that, I don't know your EC or PH #'s.

SwitchH2O. I agree, adding some Calimag would be a easy and inexpensive way. Just remember, the leaves that are already damaged will not show any improvement, only look at the newer leaves to see if that was the problem.

Have you tried adding some minerals with fertilizer?

My plants show those signs with severe nute burn...the tips brown and curl up first and then it travels down the leaf margins I think they are called..they first go hard and feel sharp and then start to brown off just as in the above pics.
The calmag deficiency shows as rust spots on the leaf and just spreads
