I have 5 DWC systems going right now all but one have 2 plants. The buckets are 18 gallons room temp is 70-80f humidity is 50-60% 18-6 light cycle with 600w MH conversion bulb. PPM in each bucket are 230-250, PH is 5.6 water temp is 67f. I use RODI water and GH 3 part flora series. This plant is Bag seed and it just started doing this. This plant is in its own bucket
What is causing these spots??

put your ph to 6.8
WUH WUH WHAT! Why 6.8 everything Ive read says a PH level of 5.2-5.8 is perfect for nutrient uptake. So why 6.8??

I like to run my PH around 6.
Ok so 2 people say its the PH but Im running it at the recommended level. If its the problem what should I raise it to? And what will raising the PH do? Will it make the plants lockout some nutrients that may be causing the problem? Or is it just the PH itself causing the problem? Sorry for the questions just trying to learn and understand as much as possible.

5.4 - 5.8 is for Hydro systems for soil grows you want it around 6.5 - 7 you are killing your plants with that acidic of a PH
My grow is DWC Hydro. Update my PH is now 6.4 I raised based on the advise I got so we will see if it helps.
