Apple fritter fem. 2-3 weeks into flowering. indoors. yellowing started on the tips and has since spread throughout the leaf. this seems to be more on the canopy. watering 1/2-1 gallon per day. FF tiger bloom every other feeding. I wondering is it root bound? seems the pot is awfully crowded with root. I may have too small pot. Ph looks to be around 6.0 using aerolight wing AW200@ 80%

ok i am clueless. what are C and P defs?
C and P are common symbols for calcium and phosphorous. Others are N for nitrogen and K for potassium. The major nutrients are often abbreviated like this.
edit: “defs” is a less common abbreviation for deficiencies.
He is suggesting that you have calcium and phosphorous deficiencies.

after thinking about i thought thats what it meant. A supplement is in order I assume. just follow instructions. thanks
How does this work?
Color blind, so I use Apera 20/60.
My healthy Green plants are at 5.8 and my plants with leaf issues, like yours, are 7.0 runoff, measured. All get fed 6.2/900 or less.
Last night run-off gave me those numbers.
Due to recent top dressing, measured run-off PPM numbers were still high, in all soils.
the Ph numbers I gave are my soil. I do have to adjust my water with Ph down. Im starting to wonder if I am using too much. would that cause C and P deficancy?
Feed at 5.8-6.2? I keep having “color issues” with my plants that are above 6.5
Not the plants below 6.0 run-off measured.
5-PH pens in 2 years.
Same Apera 20/60 since purchased.
Calibration kits verified.
3 grows lost over PH issues.
Dehumidifiers’ caused one. and bad pens, two.
I want to say thanks to all who replied. I think I found my issue. I use a vivosun programmer for my lights,fans. Somehow I screwed up and my light were on 24 hrs. so I got that straightened out and hopefully I have not caused too much harm to my plant

Most issues are related to ph. I’m betting that’s what it is.

My Cloudline controllers can become “un-set” after software updates.
Reviewing the settings after updating is recommended.
The other “problem” is slow software configuring changes (fingers faster than software.
Keep vigilant and good growing to you.

It was the light issue. I corected the problem and am seeing no further yellowing or spots. It was light burn im convinced
Thank you! Im afraid this time was my mistake. I was lucky to catch it
