Nute Burn Question

I have a little bit of browning on my leaf tips and suspect it is nute burn as I have been upping the dose gradually.
I am growing in DWC and temps are low 70's high 60's.
pH has been a little higher in the morning, adjusted at least daily to 5.5-5.9

My question is: do I back off a little on the nutes when I change res. water today? Or, should I flush with plain pHed water for a few days?

Thanks!

Sorry, here are a few pics.

Why are you continuously adding nutes? Mix the res to the desired ppm and leave it alone except for ph. Yes it appears they have slight nute burn, cut your nutes in half they really dont need a lot especially in dwc, where roots are constantly in contact with nutes. I never go above 600-650ppm in dwc.

Sorry if this was unclear. I am changing out the water in my res every week to 10 days. I started with low amounts of nutes and have been increasing each week in hopes of finding the optimum amount.

I am sure this seems basic to you, but it is new to me. I thank you 4 looking at my plants and your input is very much appreciated.

I will cut back the dosage and see how they respond. So, no need to flush with plain water? Fantastic!

Wasn't meant as anything other than help. Flushing for 24 hours between res changes never hurts but not always needed, depends on nutes, strength of nutes, and salt build up..
