While your searching the tinter web look for FE DPTA,this is the iron supplement to choose to supplement your system.stay away from FE EDDHA it dies the water blood red,but it is excellent as a Foliar application,i don’t dose my system with iron but instead use weekly Foliar applications for good results,i would dose but i am unable to source DPTA without shipping in from abroad at huge costs.
As a bi line i was from Bristol just up the road from you,hows the jolly old UK?

It looks very much like a potassium deficiency,we have no details of your system its difficult to give an accurate answer, with your ph you could dose the system with potassium sulphate at 1 teaspoon per 1000l and as a quick response Foliar Spray something like Maxi-crop this will certainly help matters.

Might be Iron and Potassium. Maxicrop plus Iron has both and you pH is low enough that you could either dose the system or spray it on. For adding to the AP water - Start with .25 to .5 Oz per 10 gallons and switch to 1 Oz per 200 gallons every two weeks for subsequent additions. Reduce or stop additions if deficiency symptoms go away. For foliar feeding - 1 Oz per gallon or about 30mls per 3.8 L then spray directly on plants weekly. Stop applications once deficiency goes away.

Please may I ask about the Maxicrop plus iron. I searched on the internet in the UK and it came back with quite a few different versions of it, mostly listed for soil growing. Would you be kind enough to post a link to the one you would use please? Thank you! Martyn

Yes postage here is hit or miss at times but not so the weather high thirties again today and now a huge thunderstorm rolling down from the mountains,drops the temp and cleans the air,it does make it easier to sleep[and several glasses of local made whiskey helps]… Nice looking system by the way..

Are the pics you took of the deficient plants on the very outside edge of your growbeds? I ask this because it looks like your growlight is concentrated in the center. Probably not the case as I don't have any experience with growlights and such, but that is the first thing I noticed. I agree with the others on a lack of iron and potassium.
