maybe P deficency?

[egz91]

Hi guys,
new to the forum and also to cannabis growing.
I am loving it. Growing is helping me in many ways...pretty therapeutic for me.
Sometimes i get into some issues like this one.
i transplanted from a waterfarm ghe to a hortipot dwc.
i know it is not best to do that but i wanted to give it a try.
I think it is a P deficiency cause maybe plant is giving it all to roots cause they are starting to grow in the bucket so maybe that's why.
Tent is a:
80x80x160cm

Light: optic led cxb 3590 cree cob. 100w.


rh: 55 to 70%


temps: 24-25 c° daytime
19 c° nighttime.

Solution is:
240ppm
ph fluctuates from 5.5 to 6.3 every 1 or 2 days i reset the ph with ph down.
solution temp: 22 to 23 C°

in solution:
RO water
sensi grow a+b 10% strength
Cal-mag 20% strength
Voodoo juice 50% strength
B52 10% strength

I think early P deficiency would have the veins down the leaf getting darker. Are you seeing any purpling of the stems/petioles? That's another tell it's Phosphorus. To me it almost looks like generic nutrient burn? You said you just transplanted. If it was me I would keep an eye on that specific plant, but I'm not sure it's anything but growing pains.

Thanks for reply,
Yes maybe your right maybe in dwc nutrient uptake becomes completely different..
Ppm where 250ish.
Now I changed nutes.
Made new solution with the 3 parts.
Sensi a+b with that ph perfect thing makes everything worse.
I will try to keep it as simple as possible from now on no more experiments just normal stuff. Hahahahha
Don't no AN seems not as good as they state it to be.
