My plants had been looking fine and then I check on them this morning and the leaves down by where my fan are looking wilted and dying. It’s about two weeks into flower temperatures at night or 75 with humidity around 55 daytime temperatures around 80 to 83 with humidity around 40 to 45 my runoff last time on this plant was a pH of 6.1 and PPM of about 1500
Does the fan oscillate? Too strong and direct can have this affect on the leaves Growmie. Heat also resembles this but don’t see that in the upper leaves 
I bet it’s just your leaves rubbing the side of your tent. your plant looks good. I wouldn’t worry about a few ugly leaves. it happens.
The fan is stationary I was wondering if it could be my fan because it is only on the backside of the plant where the fan is blowing off the wall I have turned it down. Plus, my temperature and humidity gauge is sitting at the top of my trellis netting so my temperature and humidity readings are actually at the top of the plant not the bottom. Who was also wondering if the purpling of the stock by the leaves what could that be? It is in Fox Farm ocean Forest soil and using the Foxfarm big three nutrients they’re getting the nutrients about every other feeding and I water about every 2 to 3 days when the top inch or so of the soil is dry to touch.
Where it should be Grow Bro. On the fans I have that don’t oscillate, I place them above the canopy and pointed down. Under the net looks defoliated and air can circulate through there.
I have a 4’ inch clip on at canopy trellis level running at high speed. It’s a Vizio three speed one and then I had the 10 inch stationary, one sitting at the bottom since the start of the grow this is in a 4x2 tent
You can always put one way down low under the canopy pointing up to blow air from the bottom up through the top of the canopy. The wind will strengthen the branches but more so keep WPM at bay which can be an issue in humid environments with thick vegetation
Looking good Growmie, temps and RH will work. Do you know the lighting numbers at the top of the canopy? Are you using a meter or app to set the the PPFD or DLI. Assuming these are photo period plants on a 12/12 light schedule??
No clue on lighting numbers I have a viparspectra 100w full spectrum a spider farmer 100w and a knock off 75w full spectrum tied to the top plants are about 12 inches from lights I’m doing my best to keep tying them down to trellis this has been the first grow ever indoors I’m running a 4 inch exhaust waiting on my 6 inch to come in the new one is a vivosun with Smart Control so I can try and control the humidity and temperature a little better
I would recommend setting the light numbers with a meter or the phone app PHOTONE. Over powered and the buds will foxtail and sunburn the plant and leaves, underpowered will give you airy wispy buds
It may be obvious, but when they start flowering, they “harvest” the nutrients in shade leaves and send them to growing buds. This usually starts with the lower leaves. Best of luck!
I also have a stationary fan under my canopy blowing to reflect off the back of the tent slightly upwards. I will get a couple ugly leaves back there but thats it. Rest of the plant is healthy.
Any ideas on why the one on the right has all the sudden started to burn the leaves I upgraded the exhaust to a 6 inch Vizio with the GH controller and it has been maintaining between 75 and 80° during the day with the humidity 40 to 47 lights are viparspectrum p2000 and p1000 in a 4x2
Last run off ph 5.7 ppm 1870
What medium are the plants growing in Grow Bro? I’m seeing a potassium deficiency and could be PH related
Soil is ffof was transferred into current pots early June using ff trio for nutes and cal mag as directed
What was the last run off PH and PPMs. FF fertilizer is notoriously high in salt content and each feeding should have liberal run off to help rinse away the salt accumulation. Not doing so can tank the PH preventing nutrient absorption. FF also recommends periodic flushing but can be prevented with liberal run off on feed days
Are you feeding or watering to run off and discarding this? Never let the plants sit in the run off, the expelled salts will wick back into the medium creating PH issues
I am feeding to runoff you can see the big plastic trays. I have under them, but I’ve just been letting them sit in the runoff until it evaporated that could be my problem. I have to change that up.
So my plant seems really bad not sure what to do not sure on ph or ppm anymore on it the ph has always been on the low side 5.5-6 and the ppm has been 1500-2000 since I have gotten them I have just started to dechlorinate my water I have not gave it any water that has been. Just straight tapwater and last time I checked my tapwater it’s pH is in the high 7s and the ppm are around 250. Just really not sure what to do at this point any ideas to get it back on track it’s right at week 6 of flower. I haven’t given it any nutes the last 3 waterings thinking it might be getting nute burn.
