I’m seeing some yellowing and a little bit of end curling on my fan leaves. I am on week 3 of flowering for my apple fritter auto flower. Using fox farm soil with the Bergman’s nutrient set. Should I be concerned? I did just feed nutrients two days ago. I’ve noticed she’s been getting thirsty a lot more often- I’m sure this is common but have no clue!

It is perfectly normal for the bottom leaves to yellow and eventually fall off at this stage. Your plant looks healthy.
Welcome to the forum.
Synthetic nutes?

The upper leaves that are clawing and pointing down is a symptom of toxicity Growmie. Are you monitoring input PH and nutrient PPMs as well as the run off of these 2

I didn’t notice the clawing, but I did notice the dark green and wrote it off to a bit of excess nitrogen. Good catch. I’d be interested in knowing the runoff pH and PPM too. The pH may be a little wacky given the clawing.

My assumption as well

I guess they will find out why when using synthetic you MUST have a way to determine ph/ppm.

I have not measured the runoff- as I am winging it- learning that’s not the best thing to do.
My input ph seems to be a bit high. I just ordered a TDS meter. It will be here on Saturday. Maybe I won’t kill it while I wait! 
If someone wants to give me the skinny on measuring those I’ll let you know the results, in the meantime I’ll stalk the ups guy like it’s my job.

PPM should be around ~1,000. pH should be in the rage 6.3 to 6.8 when in soil.

Thank you! I bought one of those stake testers for ph from my local hardware store- but I don’t think that it really works!

Unfortunately you can toss that prong PH meter, they work great for house plants. When using synthetic fertilizer it’s recommended to feed to liberal run off, this will help expel any salts that accumulated in the root zone from the previous feeding. Let a cup or so run out the bottom then catch a sample and test the PH and PPMs. @MidwestGuy posted some good input numbers. When your run off PPMs are lower it’s a sign the plant is consuming the nutrients, higher than your input could be a salt build up from a lack of run off or your PH could be out of range preventing nutrient uptake

Alright! My runoff PH is 7.3, my runoff PPM is 1960. Obviously that’s high sooooo do I need to do a flush?

I would water only at a PH of 6.0 and drench the medium to liberal run off…30% of what you’re putting in comes out the bottom. Follow a drench to drought routine moving forward with target input and run of range of 800-1200 PPMs and a PH range of 6.3-6.8. 2 rounds of water only at 6.0 should get your numbers back in range
Thank you! Do I need to stop adding nutrients until I get my numbers in range?
