Has anyone ever seen this?

So ive been dealing with some stress and cant determine if its defiency or lights. Im running a FCE 6500 mars hydro bar light in 5g fabric. I use cultivation nation 3 part nutrients with fox farm additionals. Ill leave feed schedule below im on week 4 veg been in veg for little over two months. Space is usually 70-75f and 60% humidity. Light was on 25% but cut back to 10% now thinking it was light stress. Ive also flushed and started using half strength nutrients . I was feeding every other watering and watering every other day i ph to 5.8 and last feeding was 1.6 EC Run off was 5.8 and 2.6EC. I Also cut light back to 18 and 6 to try and releive stress but now ive noticed circling leaves growing has anyine ever seen this? Ive gone back to 24hr light thinking maybe that caused it.Can anyine tell me whats going on. (sorry i dont have a ppfd reading)

feeding was 1.6 EC Run off was 5.8 and 2.6EC

That is a little alarming. Is this your first time with this feed and regiment?

You could flush coco like that I would think. Flush with florakleen or something and then feed right after. Idk about actual soil, flushing is probably overwatering badly right?
On your feed chart I would be trying to run #2 on an 18 hr schedule. To me they look like you could feed more.

If your run off EC is higher than the EC of the stuff going in, that means your medium is full of build-up nutrient salts. It shows that you’re either overfeeding, and/or not getting appropriate runoff. The way to correct this is flushing the medium to wash that stuff out. Too much fertilizer in the medium blocks the plant from being able to uptake what it needs. This is referred to as “lockout”. When you have this issue, adding more nutrients doesn’t help, just makes it worse.

Its the firs time using this coco coir brand with these nutrients. Is the run off 2.6 to high? Can you be soecific about what is alarming
Yes. It does seem high. It's been awhile since I've messed with that type of grow and measures.

However, when and if you flush never use plain water. Use a diluted feed solution. That is where I would start for a correction. Do you follow anyone that grows this style? I would try to find a journal/grow using this and see what they're doing or if they ran into issues.

Does your instrument(s) need calibration?

Whatever you do, they're still alive. Don't do anything dramatic to add to the stress. Do you keep a journal? Notes? Write down your process and give it time to respond. Don't think it's not working if you don't see a change in 1 light cycle. Good luck.

could be mites check with a mag glass, if not id look into root issues. let the plant dry back then give it plain ph water and test the run off .

So just an up date from todays watering.
Week 4 veg nutrients input 1/2 strength 1060ppm @ 700ppm units
Ph-5.9
RUNoff
2130 ppm@700 units
Ph6.2

So after my last post i had continued the half strength nutes these are updated pics it looks like leaves are filling back out to me what do yall think?
Bro! You got it! You figured it out! Good work my man. Stay there, until they ask you for more. Keep taking notes. Bravo! Bravo! Bravo! They will let you know when 50% isn't enough. How many days* did it take to correct?

Usually yellowing on the edges of the leaf shows a potassium deficiency. I have a plant in veg doing the same thing.
Nice job getting these back on track. Not an easy task sometimes.
 
This is what what the leaves look like today day 5 sorry its a little hardbto see i slid scrogg net down. My numbers today were 5.8 ph 1030ppm @700ppmscale nutes week4 1/2 strength . I did increase lighting to 50% on the fce6500 @ 24" above canopy. Runoff was now 6.2 ph and 1700ppm@700ppm scale. Plant is looking 100% better than what it was. And yes i will flush before flipping to flower. Thanks for everyones input and help. Ill ckme back here every so often through flower if yall want to stay updated.
