Looks like a possible mag deficiency. Check your ph first and foremost. If it's out of whack, nutrients cant be absorbed properly or at all. My range is 5.8-6.2 and but I target for 6 in soil. Fox farm nutrient trio kit is great, calmag+iron for supplemental if needed, ph control I suggest general hydroponics ph kit. Check ph and go from there. Getting that right can solve a huge variety of problems.
 
Just want to add, if done a flush with PH 6.3 water only and the run off is 4.9 so I assume this could be a PH problem.. but i could be wrong

Doing PH now m8, I'm feeding at 6.3
 
Theres your issue soil ph is too low. Coming out at 4.9 will cause nutrient lockout. They're starving. Go for a neutral ph at a 7 for a flush to buffer soil and to help neutralize whatever caused the severely low ph numbers. then feed at a 6. That should start getting the ph in the proper spot. Then it's a waiting game. Watch the tops for new growth and inspect color. Lower leaves may not change back at all.

Fyi Fox farm nutes dont need ph adjustment. A gallon mixed as directed has a ph of 6.2 roughly.

yours are very nice looking by the way i hope to be able to grow some bushes one day lol, i think the mistake i made for my first time was getting auto seeds, once id figured out what it meant i was left in abit of a panic and knew i had to work quickly lol ..my next lot are photoperiods and if im not correct you can play about with them and get them set up nicely before flipping them to flower ? more room for alterations as
 
Thank you kindly! You'll get some bushes. I promise. Photos are more forgiving because you have more time to work with them and sort out problems. I did same as you, started with the autos as they were stated to be easier. I burned the hell out of 3 autos on my 2nd grow in jan/feb. They liked to have died, but I saved them and everything got pushed out 3 weeks later. Autos are easy as you can buy just one light and set up one grow area to do the work of 2 lights and 2 grow areas as with photos. They arent as "complicated ". But with that being said, roughly 4 weeks is all the veg you get before they start shootin pistils, which is out of your hands.
 
Photos allow you to play with them and veg how you want them to veg, allow you to train and manipulate them to achieve your goals. Autos are best suited for LST as any HST training takes resources away from growth to repair the damage. Autos have their place, and advantages. But imo photos are MUCH more forgiving and easier to contend with
