Lol sorry folks, busy home life
I've got her on clean water, I reckon you're right @mellowed and it's a lockout. There's yellowing around the new leaves now which looks like phosphorous
My background EC is 0.6
I've got 5 others in DWC buckets all on 1.0 EC and doing fine. This northern lights was on 1.0 when it started showing this deficiency so I figured it was just hungry and increased the EC, but didn't work

Adding too much calcium can interfere with uptake of phosphorous and you`ve got hard water which has lots of calcium in it to start all be it shitty calcium carbonate that`s hard to use by the plant , but still some gets in and does get used, whay im getting at is the medium will still have plenty on whether or not the plant can use it and it`s this that will cause lockout of P. Just summink to bear in mind when adding calcium, tis why i like foliar feeding to correct and bollox.

Cheers Jimmi, I was just googling trying to find out what can cause phos lockout besides PH problems
I'm gonna hold off on the Calgreen, and just give basic nutes after a flush
Well if you`ve had some ferts tailor made by Growers Ark, which is a top UK fert company imo that i`ve used many times to grow good bud and it`s a bonus that they will go out of their way to tailor make their ferts for your water, well then i can`t see point in adding calcium and it`s probably maybe is that what is causing your problems, don`t put them on water cus they need ferts and it will just add to the problems, a quick flush of ph`ed water to wash out any build up of calcium and whatever else then straight back on ferts might be the way forward. Another thing is if your background hard water ec is 0.5 then a fully grown plant wants to be on at least 1.5 ec all in.

My bets on calcium def. looks exactly like mine were at about week 5 of veg. I changed my res added some cal/mag and lowered the ph to 5.5 and it got sorted soon after. My water is hard as well
