DWC issue identification

Hey lads,
so this i my first DWC grow even though i have around 4 years of growing DWC vegetables with great results, im using the same mix i always use which is Masterblend 4-18-38 + Calnit + Epsom salt, the plant was started from seed and its an unknown variety although supposedly feminized (a friend gave me this seedling but forgot what variety it is)

im not exactly sure what the issue here is since this is the first time i've grown cannabis in this way with these nutes but after read a lot of posts from similar DWC grows with the same mix of nutes i just decided to follow what they all did which is RO water, aim for an EC of around 2.0, PH 5.8-6, now it seems to me like theres some strange coloration on the leaves, and they lack any and all shine, they look very matt.

before everyone at once point out the tip curl i already fixed this, the solution was a bit too strong, took it down from 2.4 EC to 2.0 and the newest growth doesn't seem to be curling.

even though most masterblend grows went for 5.8-6.0 PH i cant help wondering if this is the right ph for these nutes.. i;ve always grown veggies in 6.4 PH as this is what masterblend advocates on their site.



thoughts? thanks.

aight, 3 peeps saying the same thing, i hear ya, ill dilute with RO water till i get to around 1.5 and wait a few days for changes, not sure if an EC of 1 is is high enough with this line of nutes, havent seen a single masterblend grow with EC that low, baby steps, i'll lower it more if not much changes.

3ml/gal calimagic
1g/gal epsom
3g/gal mega crop
1.5g/gal MKP
This is my flower mix, it takes mine to about 1.5 and has been the highest feed ive done at any stage yet.

that was supposed to say "...yet this crop."
This one I have going now is a bit of a light eater. Ive had some go a bit higher but not much.
If you make anymore adjustments today. Wait for it to settle out and record your EC and PH. Check them again tomorrow afternoon/evening if your EC is going up it may still be too hot.
If the plant is experiencing lockout, itll take a few days for you to notice it getting better.

really even lower? does it still show signs of over feeding?

is that tip burn from before or now?
what tip burn?

EDIT: in retrospect i see some of the leaves look like they got some brown discoloration near the ends of the leaves but this isnt there in person, i think my camera captures it this way because my light is a QB v2 Rspec from HLG and has those red LEDs on it.

alot of them are yellowing. zoom in.
i figured thats what you meant, its a weird trick of the camera that im trying to figure out of to fix, the parts that look brownish/orange are actually dark green, the light green new growth looks fine on camera for some reason but the slightly more mature growth is darker green but looks orange on camera, i think it might be the red LEDs on the QB?

ok so i was taking these pics with my handheld camera and it was set to capture both jpg and raw format, so i stuck the raw file in lightroom and auto corrected it and now it looks like it does in person

Let's hope for your sake, it's not a boy.
:lol: fingers crossed
