First pick is a week ago. Others are of my issue. Soil is fox farms. Week 5/6 flower. Average temp ~86 average humidity ~72. Using VPD chart for managing temps with humidity. Use foxs farms trio with flower fuel every other watering. Will water 3-4 days and nutes then 3-4 days. Ph of watering is 6-6.5. Recently added cal-mag with my watering.
I have had some days of high temps but alao high humidity which is ok based on the VPD chart. Looking for advice on next steps to fix the current issue?
That late into flower, id drop your temps and rh…
It looks like you might have been a little heavy handed on your nutrients and now your starting to see something getting locked out…
More then likely the ph went a little wonky…
Because of the high nutrient load which caused some root damage thats leading to the lockout and ph imbalance that your seeing now in the leaf’s now that its a week later…
More than likely the over feeding happend a week or so ago…
Soil always takes longer to see issues when you have them…
I would get a reading of your ph and ppm on next watering and would more than likely skip the next feeding and water only with good ph water and see what those readings are , then i would take action and adjust whats necessary… 
They are lookin good tho , other than your current issues…
Exactly. FF has required flushes at points during the grow: did you follow them? Using a TDS meter you can easily see the salt load in your medium to determine what action to take.
I am assuming you are using a calibrated PH meter to measure PH?
Do you live in a moist climate? I lived in SoCal close to the ocean and because mildew is present there I had to deal with bud rot issues. If this is the case you will need to reduce your humidity which will actually increase liquid uptake in the plants and reduce the chance of the dreaded Botrytis. At this point I would be at or around 45% RH. You may also see some small increase in trichomes as well.
I now live at a high altitude in a region where mold is not endemic and run my plants to harvest at 60% RH with no issues. So you would have to judge based on your climate.
You can (and should) also remove older fan leaves to increase airflow around the plants. Make sure you have lots of air movement in and through the plants. That will help too.
Yes, you’ve done a great job so far and many growers accentuate deficiencies in late flower: starve the plant basically.
With all the healthy leaves on that plant that’s a nothing burger. Not saying there isn’t anything wrong but at the same time the green to yellow ratio looks like normal fading. Nice looking buds btw!
I’ve used FF Trio nutes and found it’s necessary to water to runoff every single time. I would water to about 25% runoff. Collect that runoff and measure the TDS and PH. You could aslo do a soil slurry test to make sure the PH of your soil is good to go. Each plant is different which is why sometimes, it’s only one or two plants in the tent being effected.
I’ll emphasize that the FF Trio is very salty, which eventually leads to a mineral salt buildup, which submarines your runoff pH. The bloom booster can also contribute to this effect. I would ditch the bloom booster. The Trio has everything the plant needs. If you want more PK (which is all a bloom booster does) then simply add more Tiger Bloom to your feed. It accomplishes the same thing.
Do you know your runoff pH and PPM?
So here is some follow up.
Watered her on Monday and Thursday with just water
Monday:
Water- 6.4 ph; 1181 ppm
Runoff- 6 ph; 1248 ppm
Thursday:
Water- 6.4 ph; 955 ppm
Runoff- 6.6 ph; 1124 ppm
I was planning on 50% feeding this Saturday. I believe i should flush her beforehanduu with a few gallons of water on Saturday.
Any recommendations?
Wait; is this your tap water?! If so; that’s the worst I’ve ever seen.
Tap water yes but thats after using baking soda and ph down to get it right
Baking soda will trash your water and load the medium up with salts.
If your tap water is over 500 ppm from the tap you are going to have trouble using supplements for your plants. You may want to consider R/O sooner than later. I had to do this in my home town due to the high TDS of the tap water. @Not2SureYet still deals with it there.
The problem with high salt content tap water is you have to factor that into your overall nutrient load. So if you want 900 ppm of nutes you have to use the tap water TDS as part of that overall salt level. This means the plant sees much lower targeted nutrient levels.
what did you do please explain? im having the same issues
