what’s the watering habits?

I’ve been watering about every other day, or just as need and they have been getting fox farm grow big for a few weeks now.

Photo plant? What size bag is that?

Agree with @GNick55, more than likely a watering issue. Do those brown spots have a lighter yellow ring around them?

1) First, proper Ph of H2O needed ? Check it if u don’t already !
EXTREMELY IMPORTANT

2)
My opinion plant has nutrients deficiency —simple fix
Add some Epsom salt 1 Tbsp per gal next watering(add several drops super thrive) to it as well.
“Epsom salt is the best and most natural way of adding magnesium and sulfur to your cannabis plants. The benefits are astounding and there is little risk of overfeeding. Find out why you should use Epsom salt in your next grow “Magnesium also facilitates the uptake of nitrogen (N), phosphorous (P), and potassium (K)…………..”

I’ve rescued many a plant
May take a good week plus.
(I’m having problems right now with 3 Strawberry Gorilla plants rsee pic
1 is great 2 have been crappy(lower leaf yellowing spotting etc,
so
Molassas, Epsom salts & super thrive every 4-5 days until u see a difference …along with regular Nuits schedule.

Indoor plants using LED lights I water about every 4 days or so, til pots lose about 1/2 Wgt…
(for the sick plant, I may give an extra,but small amount of the Epson salt, Super Thrive and Molasses Tea mix between waterings.)
Outdoor plants here in Missouri, I water almost every day 3 gal pots, completely soaked.
(that’s about 1/2 gallon a day and they suck it right up, as a matter fact, we just got 7 inches of rain here in 5 days & the plants can’t grow fast enough amazing the difference between outdoors and indoors)!

Thank you, my initial thought was nitrogen deficiency judging by the fact that only some of the lower leaves are turning yellow and brown. Yesterday I upped my dose of Fox Farm grow big hoping that would resolve the issue, but I thought I’d get a second opinion.

That album name is on point

id honestly pluck it off and keep trucking. Thats a healthy plant. If it spreads and those spot start appearing on other leaves, and they end up doing the same, i would look into a fungicide.

If youre in a preamended soil and you havent been supplementing with calmag it wouldnt be a bad idea to start doing so

Will do thanks for your feedback.

Leaves die, they turn yellow, shrivel up and die. Those are old, lower leaves I wouldn’t sweat it. I will add that grow big is normally used as trio of nutes with Big Bloom and Tiger bloom, (and calmag). The plant overall oils just fine.
