Leaves browning in spots 4 weeks since flip

[HugePeckerhead]

So my Green Crack x Amnesia is 4 weeks since flipping. She's in FFOF soil fed with their nutrient trio. I feed her recommend dose once a week. Light was at 12 inches but just moved to 18. Shes starting to get brown spots on her leaves. Like drying out. It's only on the fan leaves on some colas. Sugar leaves and buds are fine. Anyways, is this normal for her flowering or is she lacking something. Here's a few pictures I've taken today. Please let me know what ya think.

I think they look burnt and need a flush then lower dose feeding.

It appears to be light on something and if you are giving the correct dosages for that weekly feeding, then I have 3 questions...
what is the ph you adjust to?
are you doing water/nutes/water/nutes to get to 1 time a week?
have you recently done a recommended 3x flush to clear the salts?

When feeding with fox trio as i do you need to flush the medium a few times to maintain proper uptake due to the salts in the tiger bloom.

I feed once a week and water once a week. Water feed water feed. She's not as yellow as it seems. My flash turned her brighter. I flushed last 3 weeks ago when introducing bloom nutes and was 2 weeks away from her heavy flush entering final stretch.

I usually flush 3 times during the grow. Once in veg , once when I introduce the bloom nutes first and once in the final 2 weeks

I never go 4 days without a flush till no red or colored water flows from my buckets and it works for me.

Basically feed then flush never let the medium sit incase its over loaded with nutrients and salts.

So do you flush prior to your feed then? Also the nutes suggest feed twice a week but I feed once.

Or should I count feed once a week and her watering just turn it into a flush?

If i apply green grow big i flush most of the time i put them in fresh happy frog then flip before my soil needs nutrients.The plants im growing now i have not feed only fresh soil till i start flowering nutrients in two days from now.

My key to success is never leave them in the medium long enough to start having issues.

I always started in fresh soil too. I've noticed I get around 4-6 weeks before I start feeds.

 

[BeanTownFan420]

Pop seed in 2 to 3 days up bucket to bucket i will finish them in with fresh soil veg 17 days then flip then start nutrients and flushing.

 

[HugePeckerhead]

I start fresh....4-6 weeks no feed. Flush then introduce feed. Water and feed once a week. Flip. Flush introduce bloom nutes. Flush. Feed 2 more weeks. Harvest.

I'm gonna flush her 3x her pot size tomorrow..next feed ill cut her feed in half.

Every time i have an issue its mostly spotting on leaves from needing more calcium so i flush then feed tiger bloom only because most of the time i get spotting its because the big bloom is locking out the calcium.

I feed full strength but my flush feed method prevents over feeding and salt build up unless your growing like me less maybe better for you.

I try to keep it as basic as possible. This is her first trouble with her luckily. Glad it's nothing too big. Ill report back in a few days with her updates. I couldn't find tons of info on the strain either so it was more guessing too.
