Used all the pictures and comparisons, still stumped

[bakedpwn]

Ive been battling what i believe is a deficiency. Not sure what it could be between, Iron, Mag, Cal and maaaaybe sulfur.

4x4. hlg 260 watt r spec XL, Nectar of the gods half strength regiment. It is only the sample pack though so i dont think its the full line. Has a Cal but very little Mag i understand.

happy frog in 5 gallon with solo cup size light warrior in center.
Recharge added.
just got mammoth yesterday but havent used it yet cause soil isnt dry.
I also suspected i may not have been watering enough in quantity because i was only using half gallon between 2 five gallon pots and maybe i wasnt reaching some roots.

I have bought botanicare cal mag plus since then but am waiting till the soil dries.

mephisto Creme de la chem. day 54. this problem didnt start untill about 3 days ago.

no pic is more than 3 days olds. some of the naster progressed fan leaves were alrdy removed. just trying to solve this as it seems mobile or at least a problem still.

i looked real good and there no mites i can see but i dont get a scope till tommorow.

May be related or not but this is the other creme de la chem which seems to suffer a slightly less intense deficiency or a different on all together. had to remove a leaf that went yellow on this one too. then another is slowly going now.

Some of those first pictures make me think of mites. It sure you don't have bugs?

ill check with my scope tomorrow and later today when lights come on.

Edit: i checked with a flash light and still see nothing moving. no webbing.
i agree the early damage looks like mites but i searched late damage from spider mites and my leafs yellow and brown unlike spider mite damage leaves which seem to just get more and more speckled.

Are you using Bloom Khaos? If so how much & how much HH?

I used the bloom khaos when it wasnt flowering but now its got buds so im afraid to foilar for fear of bud rot or mold. i used their 1 tsp per qt when i applied it only twice.
HH i used 1 TBL out of the 2 TBL it says to use on chart.

PPM 400, PH of nute mix is 6.2-6.3.

slurry test(2 oz nuetral ph water with 2 oz of plants substrate) ph was perfect 6.3 as suggested by nute company.

Well it can be used (all through the grow) on the roots w/ regular feeding. However anytime you use it - you must have 1:5 or 1:6 ratio of BK to HH or you will get weird deficiencies. Just something to think on...and your pH looks good to go.

o i didnt know it was good for roots too. thought it was just a spray.

- some weird symptoms mate,... not mites though fortunately,that spotting isn't what mite damage looks like,... it almost looks like thrip or some other larger sized sap sucker does, but other aspects of it looks like some of the stranger Ca defc symptoms I've seen here,...

... maybe half strength isn't getting enough Ca in there to deal with demands, plus what the LEDs do for this- ... how far away are the lights?
....meantime, look up thrips, they can be pretty tiny, but always bigger by far than mites,... then scan the plant all over and see if you spot any.. be aware they are highly mobile pests, and will literally scurry away from you when you nose around in there!
