Does this look like nutrient burn or a deficiency ? Having a hard time figuring out what they are wanting I've been giving straight water for the past few waterings because I thought I burned them. Only one of them out of 3 plants is doing this the other 2 are having different issues. Notice the purple edges appearing and light colored edges ..potassium def? Or maybe I burned them from using grow nutes too long any ideas would be helpful

Doesn't look like nute burn to me; likely a deficiency. Yellow AND purple around the leaf edges is a new one to me. Take a look through this link and see if anything stands out to you

temps low at night ? looks light they are starting to eat themselves - looks like the end of life fade in a grow room
 
Thanks for the replies . I'm thinking it's a potassium deficiency so I've started feeding it again since I don't think it is nute burn. Ive ran plenty of water thru it and my pH of the run off is 6.5 I think I've actually made it worse by just watering now showing signs of nitrogen deficient and all sorts of things .my feeding schedule got all messed up when these problems started and I was scared to feed more until I figured out the problem. I'll see how it looks after some good nutrients go thru it.they all are having different issues it's so hard to tell . Frustrating and depressing really but I'm hoping to get it figured out. I'm wondering if my soil is just used up by now they've been growing in it since late April . I transplanted one to a 30 gallon pot with fresh 707 a week ago and it's looking fantastic perked up and thriving green again. Probably picking up the nutrients in the new soil so I still think deficient is my problem

Looked like a K def to me
 
Possible k def. As u get in closer, u can see white spots and eaten areas...if u look at that 4th picture and ck that purple area, u can see a white spot on it, it's in the middle longest leaf...

Nice plant overall

Good detective work.

OP can you get more bug photos, if you can??

Look at that Grand Daddy on a date. I bet they banged.

Right. From my experience, clearly not nute burn. It's either a deficiency or bugs.

Here's another one. Now that you mentioned it, looks like two types of mites. Ar least.

I'm all-in on bugs. OP needs a 25x or greater loupe. No use looking at other things until the bugs are corrected.

Well it's a very large piece of it....then comes nutrition...hope the OP..gets started ...the earlier u do.....js..if not...who knows
 
I appreciate the replies definetly helped me steer away from nutrient burn. As far as the bugs they are outdoors and my back 40 is a swamp so I've seen some bugs on them but no evidence of spider mites or anything like that that would suck the life out of them . I think I've been under feeding honestly at this point and being in 2nd or so week of flower I think they are lacking a bit of everything after flushing them with water. Might have been my problem all along I'm not an expert but have had some successful grows outdoors for the past 4 years. Been running into issues I havent dealt with yet this year. I've been using general organics bio thrive and not sure I'm a fan of the line yet first year using these nutrients. I'll keep an update on here once I can finally get a good diagnosis
 
I don't usually get spider mites outside @Treeshaker ; it's mostly aphids and some loopers (caterpillars). Don't ignore bugs. I just use aerosol pyrethrin mostly and I usually get a ladybug infestation so that helps a lot.
 
Look at the last OP pic. Zoom in. There are little holes in the leaves.

Could a nute deficiency cause the holes? Some of the leaf edges on the other hand look iffy. And those leaves seem to have the little holes.

O/T - in my backyard I have Milk Weed planted. I don't know how the Monarchs find them but they do. It's eerie. There are bugs that seek out marijuana plants with the same voracity.
