thought I had it nailed down as a ph issue, flushed & got back into the right ph range.. but here it is again.. rusty spots... I gotta switch into flower asap as the plants are getting to big.. hoped to have this issue fixed while still in veg but.. here we are.. medium is sunshine mix #4 mixed w/ hydroton expanded clay pellets, nutrients: been using GH flora series w/ Floralicious plus, cal mag, carboload & voodoo juice w/ R/O water.. Co2 @ 700-800ppm.... humidity @ 45-65% 2X1000w air cooled HPS lights.. temps steady in the mid 70's.. I feel like I've got everything in check here and they ARE looking better than they did a week or 2 ago but this rusty spot thing is driving me crazy.. about to dip into some expensive new Advanced Nutrients Sensi 2-part, Bud Ignitor, Voodoo Juice, etc. don't wanna waste this stuff on effed up plants..​

do you have a good magnifying glass? i was just reading u on thrips and it looks like it possibly matches early thrip damage and what i was readin was saying they are about the size of a pinhead to invisible to the naked eye basically. also with RO water you need to supplement EVERYTHING try switching to tap for awhile if your worried bout micro nute deficiencies. why pay for all those minerals that the city gives you for free? i used to use purified water from a little water store in town then started gettin lazy and just balancing my hose water. my plants since i started using the hose wwater are ctually more healthy then my last crop with the purified. could be the strains but i also have clones from my last crop runnin along side everything and they seem to be doin better then last time as well. didnt change up any of my nutes.

just to update.. shortly after my last post I sprayed the plants with Garden Safe Fungicide 3 then once again like 2 days later.. picked off all the suspect leaves & I'm back on track.. everything's lookin' awesome!!!
