help please

so i noticed the leaves at the bottom of my auto are yellowing out and getting rust spots. its starting at the tips of leaves working its way back to the stems and im not sure whats going on.
the plant its going on week 5 in ffof soil. my other 3 plants are doing just fine no deficiencies at all.

no nutrients used yet just running of nutes in the ffof soil. this plant is also showing sings of to much nitrogen (the claw) im not sure what to do at this point.. plz help me out guys!

5 weeks is too long without nutes. Feed 'em now. Half strength.

Discoloration from bottom up usually is a deficiency

FFOF is good for 3-4 weeks max.
You have to start feeding. Lightly.
Clawing is not always nute related.

Another Fox Farm victim

Fox farm is good if you know how to use it. Agree with Saltz on the claw too. That could be wind, overwater, heat ect

gotcha! i appreciate you guys. i didnt know the claw could be caused by wind. ima cut the fans back and feed tonight!! again thanks everyone

Not sure how you have your fans setup but I’d put one blowing above and below the canopy , not directly on them. That’s when some curl can happen, not saying that’s the prob either. Just not directly blasting them

What kind of water are you using?

1/2 strength feeding with whatever you use, and 5ml of calmag per gallon of water used. Then give her a few days to resurrect.
All you did was use the soil til it was spent. Remember how long that was? Keep it noted for this strain at least. Feed 1 week before the date of these pics to catch it before it's looking like that.

Do you know the ppm and pH?

And what do you plan to use for nutrients? Chemicals or organics?

I started in FFOF and am still using that original stuff as my base.

Those plants don’t look like they have nitrogen toxicity. They’d be super dark green and glossy and claw . They are getting hungry . As said before , by other guy . . Fox farm is a hot soil . Should be good for the first 20-30 days , depending on watering habits . Also it’s soil is prebuffered at 6.3. I like ff. It’s simple to use . Just my opinion

ppm is around 40 and ph varies i water in between 6.3 and 6.8
this grow im shooting for organics. i just top dressed the plants with gaia greens 2-8-4 and was gonna see if that will hold these autos off until buds are ripened. im in preflower stretch now. have you had any experience with gaia greens fertilizers? heres a pic for ya

Fox farm for some reason or another gets a ton of hate . Idk why . It doesn’t give me trouble . The only negative thing I can confirm that I’ve heard is gnats. Aside from that idk. Your plants look good . Good luck with your grow !

That's awesome man. Your well water is cleaner than mine. Lucky you. Mine's not bad at like 150 and around 7.6-7.8 pH, but yours is better. I'm jealous. I had a feeling you were going for organics, but I had to ask first because it makes a difference.

Now that I know the water you've been giving, reaffirms to me that it looks like the start of Cal and Mag deficiency on those lower leaves. FFOF is a little short on Mg I thought. Makes sense with your soft water.

I've never used Gaia, but it's good stuff. One thing I've heard is to give it less than you think, because it can burn. So less more often.

Also, organics like that take awhile to break down. So plan on a couple weeks before you see much change after top dressing with that.

One thing I like to do now, is to mix my dry amendments with some compost or EWC and a little pumice and keep it moist, but still let it breathe. If the mix is hot, then let it cook longer, until it's room temp. Then less worry about burning up the plants with hot amendments.
