Ok so I had a good look in the tent today and decided they are not recovering as I'd like them to. So after the better half gave me another ear bashing for going to flush them in the bath again I took them outside.
Where under natural light I was able to have a good look at them. I have two plants with four problems between them, The Soviet Ripper is suffering from phosphorus and potassium deficiency and the Northern Lights is suffering from Iron and phosphorus deficiencies and leaf twist.
I gave them both a flush with 30l of plain water ph'd to 5.6 then a mix of 3/4 strength feed ph'd to 5.7/5.8 it woulldn't stop fluctuating but it's ok.
Believe it or not these pics were taken at 4pm this afternoon and not the middle of the night like it looks, good old British summertime.
So now I have worked out what is wrong and what was causing all the problems, my ph was too high yet again it's been around the 6.1/6.3 mark which is high enough to cause all the above issues hopefully fingers crossed this time I've got on top of things now...time will tell
Soviet Ripper if you look at the leaf in focus in the middle you can see phosphorus deficiency and the two in the foreground are showing potassium deficiency early stage
Same on the two leafs to the left (phosphorus)
This is classic potassium deficiency outer edges of the leaf turn brown and curl upwards(big leaf is later stage and leaves off to the right are early stage)
Over shot of soviet ripper showing potassium def
Side view showing difference in colours from top to bottom potassium towards the top and phosphorus towards the bottom on the darker leaves
Northern Lights side view
Northern Lights with discolouration (the camera makes it look yellow but it's more white) iron deficiency as well as leaf twist caused by high ph also they are very dark green with like a blueish hue to them and purple stems which I think is phosphorus
iron deficiency (camera makes it look yellow not white)
Last 2 pics I think are a combination of iron and phosphorus deficiency
