If your PPMs are as low as you say, the problem doesn't sound like overfeeding. Your Ph values look pretty good and your light sounds more than adequet unless too close. Did you just start using any new lights recently? I'm not familiar with your nutrient, but I would try to get a general purpose fertilizer with some, but not a ton, of Nitrogen, simply because you are in flowering (otherwise I'd use 20-20-20). You aren't showing Nitrogen toxicity, but bad P/K ratios can cause lockouts... not sure if it would show up on a PPM meter like some things do.
On a side note, they could also be approaching the end of flowering, which often causes leaves, especially the lower fan leaves, to yellow and drop off. With the small pots that they are in, the nutrient reserve isn't too high an they might just need a snack... unless it is just old age!

thanks everybody! still figuring out how to use thcfarmer.

okay so no new lights, 2 1000watt hps with supplemental led lights (2 1500watt yehsence led)

if i bump up to two feeds a day what would someone recommend my PPM going into the pot be?

i’m only in the middle of week 5 of flower so i don’t think they should be looking like they are for what day of flower i’m at, but i could for sure be wrong about that. i still have 3-4 weeks left until harvest, probably closer to 3 weeks left

Its a coco grow. Could be a calcium thing or need more feeds per day or something. I figured i would bump the thread for a coco advisor again since you commented too. :-)

it’s a 9x16 room ceiling is almost 7ft but lights are at about 6.5 ft. and absolutely i totally agree about the redwoods, they should be almost to the ceiling but they were super stressed in the beginning, this runs been a big learning experience to say the least.

That's a LOT of light... how big is your grow area? If possible, can you post a pic that shows the whole plant so I can get a better idea of it's size? With that much light, you should have redwoods growing!
***** UPDATE ****

I looked at the photos and saw that they were MUCH bigger than the pictures suggested. I It looks like you defoliated them and I think that is where the problem lies. The larger leaves store nutrients to use primarily during flowering and seed set. Without the larger storehouses, the plant starts to use what it already has stashed away, especially if there isn't enough of a particular nutrient present. I think the plant probably is hungry but I'm unsure how much a plant of that size is hungry for.
I don't trim more than a few leaves off of my plants, but that is just my style. I know that some defoliate aggressively (looks like you might lean this way). I also grow them pretty tall, so I get a lot of yield from the side branches as well. I don't normally see yellowing until about 7 weeks into flowering, depending on the strain. The reason I asked about lighting was last year I swapped out bulbs, using a 10K "finishing" bulb. I'm not sure how much it helped, but it killed off a bunch of fan leaves but left newer growth intact...within about 3 days!

Is this your first grow ?

I mostly grew in DWC, eventually using almost all of AN's lineup; did the same, with the full lineup, in 100 and 150 gallon ProMix filled bags. I can't say enough good things about AN (although i'm sure others love what they use just as much); one of those things is not on how accurate their dosing guidelines are though. I can't really see how far along your plants are, so i won't say that you're feeding too heavily.

Although from another forum, i've always found MynameStich's Sick Plant Guide to be a boon; lots'a pictures and he speaks of multiple grow mediums.

here are some more photos taken through vision sun protective shades to try and get the color more accurate. some are pale, rusty, yellow and darkish. i raised my lights about 8 inches or more, two 1000 watt hps and two 1500 watt purple led, hit them with some enzymes tonight but still wondering if i should just flush them out
