No i do not foliar feed... and no White fungus or anything i did battle Root rot but the roots are amazing now Super White and Fish boney looking (hairs that come off roots). I just cant seem to figure it out. I am gonna do a Full Nute change and leave PPM at 1350. The only thing i can think of is these Damn Fungus gnats i will get a root pic soonDoes not look like insect, i think nute burn or a fungis, if it is white it is a fungas but I cant tell from photo if it is white. Do you spray them with anything durning light hours? If so stop it.
I forgot what week but its been over 3 months and i fought root rot for about a month so itd gotten about 2 good weeks of veg so far and then i started seeing those dots at about 800ppm so every 4 days i would up ppm abd yesterday i put it to 1350 from 1150well, it's definitely not the light. you can actually move that 400w a lot closer. i keep 1000w lights 18" and 600w lights 12" for the most part. I'd move it down to 12" if heat isn't an issue.
i'm inclined to think it is a burn of some kind. 1400ppm at that stage is a ton. i'm never really over 900ppm in veg and only push certain strains to 1400ppm+ in mid-late flower. what week are you in veg? not counting cloning/seedling stage.
yea, i would try and keep the pH more stable and back off the nutes. see how that does.I forgot what week but its been over 3 months and i fought root rot for about a month so itd gotten about 2 good weeks of veg so far and then i started seeing those dots at about 800ppm so every 4 days i would up ppm abd yesterday i put it to 1350 from 1150
