Brown/copper spots ?

In the words of Waria "do you have a soil meter"? I would guess calcium(I am no expert). I am going to guess you medium has enough calcium at this point(pure assumption as I am not familiar with fox farms). PH is probably more of your issue. If your growing in soil do not flush just for the sake of flushing. Find out your PH if it is low adjust your feed PH up to level out the PH in the soil. I try to shoot for 6.5. Flushing soil will just wash away the nutrients that are in there. Flushing should only be used if you overfeed your medium and or salt build up. Since you have not used nutrients yet I doubt that is the issue.

Time to start feeding Ca-Mg and nutes, start with a dilute solution.. how much depends on the NPK#'s, what are you going to use? I see Ca defc. but P defc. can look similar,....

So im usinf the fox farm trio of grow big bloom and tiger bloom. And you think nows a good time to start adding the cal mag and nutes ? Im glad i grabbed cal mag when i made my inventory list. So as of right now i will ph my water a little higher. I did add cal mag on the last watering but i did half strength of what the bottle said to be safe

Okay im glad i waited for feedback before making a rash decision thanks for all your input guys i really appreciate it

It looks like a calcium deficiency man, I wouldn't flush if I were you unless absolutely necessary. I would raise the ph of my feeds to 6.5-6.8ish and add cal-mg at full strength and see what happens. Affected leaves won't change but keep an eye on others to see if the problem persists. I only grow outdoors so take what I say with a grain of salt

nks its looking like its a C def feom what im seeing so hopefully cal mag and nutes gets her back on her way

Personally I believe you can raise your calmag amount. Like others have said you really need to know your soil ph though. If your soil ph is low 6’s your calmag is not not being taken up and it’s essentially doing nothing so it important to get that ph in the mid to slightly above mid 6’s for her to start taking it up.
As far as nutes, yes I think at this stage you can start feeding her a little. Start at quarter amounts of the feed and monitor her tips for browning. I don’t think you’ll have a problem at all at such a small amount but better to start low and increase as you go. By late flower for me I was putting over a full suggested amount of the trio and running around 1000 ppm. But make sure you ph your water because using the trio will drop your ph. I use RO so it’ll be different from you but my ph was around 5.5 after adding the trio of nutes to it.
Scour this site and read through other threads you’ll be amazed at what you’ll learn. Also another little tip that helped me. Take pictures in good light and diagnose your plant that way. I found that looking directly at my plant was harder to cross reference my problem because I’m looking at pictures of other plants. It seems to bring out the deficiencies through a photo better. But maybe it’s just me.
Good luck.

Thanks man im going to take all of that into account and get that water ph level up and add nutes on the next watering. Ill let you guys know how it goes. Im also going to follow your grow to see how yours turn out thanks again to everybody who is trying to help !!!
