Don't know what issue is. Plants are in flowering stage for about six weeks. Using FloraNova bloom one tbs/gal up until about two weeks ago when this started happening. Went to straight water for about a week then to two teas/gal. Watering every other day. Temp at 73. Humidity at 55% Using Happy Frog soil with perlite and COCO mix. Using water from de-humidifier. Haven't checked PH but going to. Any input will be appreciated. THANK-YOU in advance Using T-5 lights 8 bulb about 12" away raised lights to about 2' away

You're using water from your dehumidifier? That's a new one... why are you using that?
 
Before I even started reading I was like "damn, those got cooked.." I was a little upset to see the same answer here :/ I hope it can recover just fine, Midnight!..
 
I just got a new dehumidifier a couple months ago and it has a bunch of warnings about not drinking the water. I know it sounds like it would be like distilled water but the warnings say otherwise. Just say'n.
T5 bulbs 12" away doesn't sound like light burn to me. Check that PH and the PPM of your water going in and coming out.
I know you are getting conflicting opinions but that's all just part of figuring these things out.
 
It does look like your burned the leaves, but since you're using T5 grow lights that were 12" away I'd be really surprised if it were light/heat burn unless it got really hot. T5s are normally kept just a few inches away.

So my first suggestion is to probably stop using water from the dehumidifier just to be safe. Checking the pH is the next thing I'd do since that's the number one reason you see deficiencies. In my experience plants get a lot more picky about nutrients and pH in of the flowering stage!

Are you letting the top inch of soil dry each time before you water again, and are you removing runoff water? Did anything new or unusual happen (new supplement, change of environment, etc) right before you saw the symptoms?

Last question I promise: Could you post a picture of the whole plant in the setup? Sometimes that helps us spot clues :)
 
I was wondering what the ph was with my dehumidifier water one time, it was right on 6.00 and another time it was 7.00 my tap is 6.44 I really thought putting it in my tent I'd get a light green tint water (Nope)
I wouldn't drink it so my plants won't either.
 
I would not use it on my plants either....that being said...my wife waters all our house plants with the water from our dehumidifiers and they all are healthy and vigorous. I choose not to use it on my plants because the water seems a bit slimy to me and I'm just extra picky when it comes to the health of my plants down stairs.

She also dumps our leftover coffee we did not drink in her plants...right along with the used coffee grounds...go figure....seriously her house plants are crazy
 
We dump used coffee grounds on all our outdoor plants. Supposed to be really good for plants and they do seem to like it. Don't know how good it would be for pot. It would be interesting to hear opinions.
 
Watering every other day. Really don't water to create runoff. Did stop using dehumidifier water today. PH of soil at 7 water was 6.5 new water at 6.0 Will post pics Also use nutrients every watering

Cannabis plants definitely do better if you get at least a little runoff every time, and make sure to remove it so it doesn't get sucked back up. They grow best with wet/dry spells. If you're still having trouble after your other changes, it can't hurt to try, and it'll give you a chance to test the pH of the runoff water :)
 
If you phed it with something it should be good enough,it comes clean ready and phed though in supermarkets quite cheap,even where im from where hardly anyone knows what it is lol!!
 
Hey my dad always did that but with Turkish Coffee (boiled not filtered with a very thick layer of muddy cofee grain at the bottom of the cup)!Used to fillit with water and throw it in there...Not very useful in hydro,clogging warning...
