Highest Temp (lights on) 88Deg. F
Lowest Temp (lights off) 74Deg. F

Highest humidity 60%
Lowest humidity 33%

Fans always on when lights on
Fans come on for 15 mins every hour when lights off

Leaves affected are mainly lower to mid fan leaves. Areas of damage have a dry crispy feel as well as the green on the same leaf. Papery feel. Not all leaves feel this way, just the ones with areas of damage.

I've been trying hard not to overwater them. Perhaps I'm not watering them enough? Possible deficiency? Over-fertilizing? I have no clue. Buds look nice though!294364294365294366294367294368294369294370

There is a trouble-shooting form "sticky" in this section, more information would probably help some of the more knowledgeable folks in diagnosing this. :thumbsup:

I agree with the doctor, some of that damage looks like it's been wind-blown.

Have they been in those pots for very long? What's the medium? Is pH stable? :detective1:

They've been in these pots since they were transplanted after cloning. Medium is soil (happy frog). They do have fans blowing on them a lot. Fans can damage the plants?

1) Specific brand and type of soil?
Happy Frog

2) Size of container?
5 Gallon

Your nutrients and water:

10) Source of water?
Tap adjusted to Ph. 6.2-6.5

11) Method of checking water ph.?
Electronic pH meter, calibrated using ph7 solution

12) Method of adjusting water ph.?
ph up & ph down

15) Any additives or tea's? (Superthrive, CalMag, molasses, Mother's Earth...)
No

16) Are your ph levels stable, or do they fluctuate?
I try my best to keep water and feeding mix at 6.2-6.5 and run off water at 6.5-6.8.

17) What is your ingoing water's ph? ...your runoff ph?
6.2-6.5, 6.5-6.8

18) Do you foliar feed? If so, with what, how often, and at what time do you spray?
I spray leaves with pH adjuster water with nothing in it once every few days.

Your growroom:

19) Indoors or outdoors?
Indoors

20) What size of closet, room or hut?
6x5

21) What are the temps and humidity levels while lights are on? ...With lights off?
Highest Temp (lights on) 88Deg. F
Lowest Temp (lights off) 74Deg. F

Highest humidity 60%
Lowest humidity 33%


22) Have you seen signs of insects in the growroom?
None. I use a pest strip (hotshot). Not a damn living thing in there except the Mary.

Your strain:
23) What strain are you growing?
Holy Grail Kush

24) From seeds or clones?
Clones

25) Is this an autoflower strain?
No. 9 weeks of flower says DNA Genetics seed bank

Probably heat damage, at 88F. Are you adding any ferts to the leaves or spilling fert on them? If you spill fert on leaves, it will kill the leaves in areas just like what you have there. If not, then it's heat damage.

yea I agree

looks like sunburn, raise your lights, other wise looks fine, some leaves will turn and die off eventually, you could cut the burnt parts off the fan leaf, rather than cutting the whole leaf off if your worried.

Misting leaves+grow lights=burns. No need to mist a budding plant

Shit, thanks. Been misting them daily. No more mist. Oh, well. I've only got 2 weeks left out of the 9 week flowering period. The buds are just starting to explode in size!
