What deficiency is this & how to solve it

week 5 of flowering:

I caught a whiff of the blueberry plants first thing in the morning & it was soooo nice & fruity mmmmmmmmmmmm.
So far so good the buds are growing & thickening up nicely. However one of the plants has decided to go rogue & is beginning to play up, not only are the leaves turning yellow but some of them have a brownish/purple/redish smear (see pics). Whats happening?

I was considering flushing with fresh water but Im using a drip feeding system (4 pot Atami wilma) so all plants are fed from one tank, Im confused on how to flush just the 1 plant while continuing to feed te rest with nutes. Any help?

Am I right to assume that even though all 4 plants are from the same mother & cut at the same time it doesnt necessarily mean they will end up looking the same?

correct you get a few strangers in almost every group

Hey I got one of those
It jumped right into my bong...:^P

might be ph the yellowing is usualy from that just try and gets a test kit you can get em for coppers just looks like the one behind it is getting a lill colouring from the leaf edges not all plants wil react to the ph just depends on the clone could be a bit more sensitive than the rest if you can try pulling off some of the orst leaves as it always seems to spread round faster when you leave em on dont wory bout triming it just dont go mad and strip it bare lol

not to sure bout the redish colorings might be a temp problem as plants tend to go redish purple when temps drop below 50 usualy at nite and can be if the air is humid and a draught is hitting the plants just with it being at the front near the door and as for flushing you might just have to flush em all or try disconecting it from the res and hand feed it but if you are in clay pebbles hand feeding can be as much as 4 times a day as they dont hold liquid very well hence why there great for the drip systems

I think it is a Nitrogen deficiency that or its under the HPSs hot spot, Ill move it around & see what happens, if that doesnt work Ill flush it by hand. These girls only have 3 weeks remaining so I hope this one doesnt die on me. Much appreciated for all your comments.

i don't see signs of strong nutrient doses on the leafs. Ideally i try to get the very tips of my leafs to burn a tad and the edges of the leafs ridge up a bit. But Less is Better! Is a good rule as you try to bring up the ppm levels. They are not getting the N right now. but right now you don't need N. If your nutes are up to max tolerable levels then there is something locking out the N. high PH or Not enough flushing? With two weeks left I'd flush and give lesser nutes and prep for flavor by letting the nutes run out of the plant. I have had plants randomly die with no reason. i don't think this is your fate.

Thanks dude, Im using just under 1/2 strength Ionic nutes, I just hope its not root rot though I am using Hygrozyme. I hope she makes it for harvest finger crossed.
