Nutrient Deficiency?

Hey guys, wondering if I could get some help with identifying this nutrient deficiency. These are Auto Tutankhamen. I’m currently running an outdoor RDWC, temps fluctuate between 70-75, PH is currently at 6.3, PPMs are at 380, running Remo Nutrients at 50%, found their hydro schedule was a bit much. I’m at day 19 from seed. My best guess is Manganese deficiency due to the current PH, in which case it can easily be dropped. Any help would be greatly appreciated. Thanks.

i kinda see a lot of white spots and webs in pic 1.
my guess: spider mites. you'll need a scope or loupe to see them.

We have a lot of Poplar fuzz flying around this time of the year, so that would account for what appears to be some webs. Specifically interested in what’s causing the interveinal chlorosis. Overall health and growth is great, just seem to have some discolouration.

the possibility of you having a Manganese defic is highly doubtful with any decent nutrient . which is why i suggested checking for bugs. since you are outdoors.

Just checked out the tops and bottoms of all the leaves with no signs of any insects or webs.

They don't look that bad, your numbers all look fine, I'd say the roots are still growing and they are just adapting to their environment.

if not bugs, then they might need just a bit more Mg (magnesium). do you have any Epsom salts?

Dropped the PH down to 5.5 and increased the nutrient load to 500ppm as per Remo’s recommendation via email. Having a hard time believing that it’s a lack of nutrients, but I’ll give it a try. It’s 100ppm less than recommended, but I don’t want to fry them. As for the PH, the method to the madness is to allow better uptake of Manganese(see chart). I’ll give it a few days and upload some new pictures. Thanks for all the input so far guys, it’s greatly appreciated.
