Check the ph and if it’s out of range get it back to where it needs to be then LITFA for a few days to see how she reacts. If no change I’d be adding a little magnesium to the feed. The UK water supply is high in calcium so you don’t really need a proper calmag supplement.

Pink under the leaves can be phosphorous def, potassium gives a little burn right on the leaf tip before it progresses to the edges of the leaf. The evenness of the yellowing I would say is a N def, as its in stretch but upping the mag wont hurt
I would say mag on this one its more blotchy brown spots. Provided the PH is good.

Funny ya say that. Spoke to the guy I got the cut from he’s been having to up his dose over the recommended amount as the plants are starving. Think I’m also gunna have to do separate bloody feeds too as they’re all acting differently 
oh the joys of growing eh. Will do a runoff test tomorrow and post up what numbers I get.

Did my runoff tests definitely deficiencies my PH of water in was 6.1 and out 6.5 then EC in was 0.1 EC out was 1.0 so isn’t a PH related issue and they’re feeding as EC in is around 1.4.
Have noticed after the feed yesterday the stardawg had more green on the yellowing leaves so upping to 4ml per litre A and B might of done the trick but have noticed a bit of tip burn on one of my GSCs so I’m thinking my mixes haven’t been thorough enough so will make more effort but have bought n ordered the Epsom anyway as I’ll prolly need bits throughout flower.
Had a good look at my pollinated buds after I’d gathered the water and it seems to have done what I wanted it to.
Just noticed after uploading there’s a fackin mite on that leaf behind it. Missed that one when I was in there

They do look a lot better on these more recent photos mate. 1.4ec is only 700ppm and UK tap water is 150ish so plants only really getting 550ppm of nutrient. Maybe they just hungry and eating themselves??

That’ll also show as a lack mag deficiency so…

Tap water was less than 100ppm as that’s what 0.1 covers on that truncheon or here anyway but thinking same thing bro maybe they just crying out for more food. Still gunna give em a shot of mag n that cos I do reckon it’s that. The washing machine looked sick from day dot it hates nitrogen with a passion really sensitive plant. The rest are pretty hardy bastards hungry for more.

The ingredients are:
- 5 liters of your favourite water
- favourite npk at your desired ratio
- 1 tablespoon of blackstrap molasses (organic hence without sulphur dioxide)
- 1 teaspoon of Epsom salts
- 1 teaspoon of brewers yeast
- 1 teaspoon of malt ( barley or Horlicks… man maybe even malteasers just kidding those are for you while you watch em get nice and healthy)
- 250ml cup or favourite heat resistant cup vessel container ( Stainless steel, old mug , mason jar… etc)
To make things easier, heat up about 250 ml of the 5 ltrs and place in a heat resistant cup, place a tablespoon in the hot water for a minute or two, it makes it easier to get the molasses out of the jar and to dissolve it. Mix everything in the 250ml let it cool down and then just add to the bigger 5 ltr container.
The recipe above has-been used in Coco and the guy says they smell great. Hope this works for you.
Oh I nearly forgot, a dash and a sprinkle of TenderLoveandCare😁

What is a heat resistant recipient?!?

Stainless steel, old mug , mason jar… etc just to prevent any silly accident. Some.plastics don’t do great with hot water 
Trust me, you won’t want something really hot spill over into your arm or pants…or
