Plant Help Please (WK 3 Flower)

Hi Folks,

Anyone have any idea of the issues I may be experiencing. This is my first grow and I understand there can be a large number of reasons for different issues. I am currently growing 3 bergmans gold leaf in 5 gallon DWC buckets. Each has one airstone and I use 3 gallons of nute solution. 12ml calmag/8ml micro/16ml bloom/6ml hydroguard. pH is normally 5.5-5.8 with fresh buckets.

Give cal mag or increase it rather. Or perhaps foliar.

Very nice looking plant by the way. Good job.

Rust mold on 1st two, I'm pretty sure......let me look some more......,f'ing beautiful otherwise....you're 1st grow ? F'ing a ! .......impressive......,,,the third plant; looks like c hlorosis, I think.......chlorophyll deficiency............maybe pH....also on this pale green plant with a great body , it "looks like" something was splattered all over it.....could be....or bugs , wounds , some disease, munchies, looks like from picture small spots all over, some white, some light amber.........all the way to right center of pic it " looks like Little brown bugs, aphids....,,.....tough to tell from here, I'll be right over and have a look.

Thanks guys, yeah I was having trouble figuring out whether i burned some of them or whether it was calmag. Hate dealing with large pH swings in these bubblers. Next run RDWC. Also its all indoor and i havent seen any pests. Maybe ill do some spring cleaning
