New Grower new member and hydro newb with first deficiency

[green grass]

high guys. new member and hydro newb here. ive just posted an introduction but basically this is my second hydro grow after moving from soil and all of a sudden today i have a deficiency.

the large plant is an autopounder and has the def. the smaller plant is a think different and is fine except very slow.

ive just moved them from my large tent into this new smaller tent that was intended for starting off but ive ended up having to finish them in here. i have been having some problems with my new timer as it has fecked up a few times in the 3 days ive had it. im taking it back on monday.

so its week 8 day 1 from seed and week 2 day 4 of flower.
since flowering started ive been feeding canna aqua flores and big bud for a week but then switched to pk13/14 at 1/4 1/2 3/4 strength for weeks 1,2,3 of flower. im also using great white bennies and was told to feed full strength pk at week 4 of flower.

1.5ec
5.8ph
res temps 18-21c
room temps 70-85f
rh 50%

ive just converted the 2 oxypots into a iws dwc flood and drain type system so both pots are connected to a header bucket which is then connected to a res which is where i feed ect.

can anybody advise me on a general rule of thumb auto feeding guide from my armoury below please as this is where i lack confidence?

aptus root stimulator (very good stuff and much cheaper than rhizotonic)
aqua vega a&b
aqua flores a&b
big bud
pk13/14
over drive
plant magic magnecal (cal/mag)

should i increase pk to treat this deficiency?

any help would be greatly appreciated

cheers gg

ur buds look almost ready just read up on the auto pounder its 70 80 days. So ur over 60 already. from what i seen read and noticed first hand when the buds are almost ready they starting eating away at the surrounding leaves leaving a yellowing color. im no expert by any means but ur buds look almost done so it might just be a case of ur buds taking the energy from the surrounding fan leaves.

cheers guys. its not ready yet mate as the pistols havnt even turned brown and the buds aren't formed. they look bigger in the pics. im planning on around a 11 week grow so i hope its not done yet lol
its just strange that it appeared so rapidly and nothing has changed other than my timer playing up?

yeah yours looks like nice bud mate. ive done these so called super autos a couple of times before and they took 12 weeks. the trics havnt gone cloudy yet so im confident that my timing should be ok. the think different is the same age and is way behind. i think my problem is due to my ph rising and possibly locking out p/k but im still learning so not 100% but i do know that most hydro problems are ph related.
im going to read up on here and hopefully link up with a dwc grower who can guide me on feeding ect as im ok with photos but ive always struggled to find a perfect feeding schedule during flowering of autos and now i changed to hydro nutes i know even less lol

thanks for your input guys
