bud tops are yellow

[Funkfarmer]

Hey all, i am seeing something i have never seen with my plants. I have two WW in bloom, about 2 weeks from seeing flowers. they are dwc with gh 3 part and fox farm adds. last harvest i was seeing brown tips all over so i adjusted to not get burned tips, but they are still a little burned and the tops of the buds are very light green even yellow. they look healthy, but i am concened. any ideas? Thanks

[Funkfarmer]

Yeah, I did move the lights closer. So that is what the problem is?

What is your pH? What are your PPMs?

 

[Funkfarmer]

ph is 3.7 and ppms are at 500

Nute lockout due to PH. You need to get that PH up to 5.5-6.0. PPMs seems low too, I assume you aren't feeding because you thought the problem was nute burn?

ph is 3.7

Can plants live at 3.7 PH?

Can plants live at 3.7 PH?

They still look good, my meter is calibrated. I just, on this grow started checking ph and ppm. I have had 4 harvests before this and no probs, I would just add nutes(check ph and ppms and all was fine) so i just kept up the same routin. (Everything was good right?) Until i changed the routine, only because i wanted to do away with the burned tips. So what do i do? Do i go back to the same routine and just deal with burned tips? Thank you everyone who responded.
