Hi, so I'm not %100 sure but I have recently had a similar issue and it was diagnosed as a cal-mag deficiency... Your problem looks very close to what I have. I'm sure others will be here to verify what it is but hope I could be off some help.

Clearer photos would help to diagnose and so we can see the beauty along with the issues.

Edit: I am also in soil and not hydro.

I thought that myself so i brought some calmag ive been feeding calmag for the past 5 weeks it made no difference also pics are trash cause i have a bad phone i will ask my friend to use hes phone thanks for trying to help much appreciated
 
Sorry wish I could help further but I have only dealt with soil. I've read through here a bit on all styles of growing...maybe I can help figure it out. Have you looked at roots make sure they're white and healthy? You mentioned high ph at "7" every two days after returning it to "6", is there a chance of a nute lock out? As you mentioned you have been giving it cal-mag for 5 weeks now....and nothing is changing?

Good morning @agedmaster welcome to 420magazine .
Your ph is too high :Namaste:
5.8 and put calmag in water first wait a few minutes then add you nutrients.
Then set ph last.
5.8 they will start eating.

Stay safe

K, Ca, Mg defs show up on the leaf margins first
Looks more like a Phosphorous/micros def to me (possibly your wandering pH)

Thanks bill ive been adding all nutes at same time will put calmag in first

It's important for proper nutrient uptake.
Cal Mag in first then go have a smoke :ganjamon:
Then add your micro then grow then bloom nutrients then set your ph to 5.8.
They will start to eat.
How are your roots?

Stay safe
Bill

When i first got my cuttings i was feeding every 15 minutes for about a week as i was told to after searching realised once per day im not sure if over feeding at start would cause this to happen also the leaves that are affected get a purple stem then curl up and dry out ive taken about 100 leaves off them through out the grow cycle

Stop taking leaves. :Namaste:
Never take a leaf off unless you have pests..
You just make the problem travel to the next one.
Plus she needs them.

Can you get your temps down at all?
They would be happier at 22c.

When you say 2 days after flushing how often do you flush?
At ph of 6 ph you make certain nutrient unavailable.
Are you following the schedule for your nutrients?
You say they turn dark green? How much nitrogen are you feeding?
What ppm are you at now?

could fungus gnats cause this

If you have a bad infestation of root fungus gnats it can cause problems.
But I've never seen it in hydro.
Your ppm should be in the 1000 range say at week 3-4.
It would benefit you to get a ppm meter.
They are inexpensive.
We don't know the ppm of your plain water so calculating final ppm is difficult.

Stay safe
Bill
