Absolutely nutrient burn related. I agree with high roller. Water only next few times then dial back on the nutes some.

Yellow/Brown Crispy Lower Leaves
Why are my lower leaves turning yellow/brown and crisping up? Is this a nutrient deficiency, the top leaves appear to be good still, but it looks like it's slowly making its way up the plant.

Leaves continue to get yellow and fall off. Plant dying, bud looks okay.
Still having issues with my plant. Leaves are getting more and more yellow and 2 have fallen off. Pretty far from harvest still for the leaves to be getting this yellow. Temps in tent are 18-22 c with leds 200w act wattage. Overwatered once but I doubt it would cause this. Ideas?

What's going on with my clones? Do not have much information to add. VPD is not terribly off, DLI around 25.
What's going on with these clones? Not sure what it could be. They could possibly be rootbound. They should have been transplanted a few weeks ago but I did not have the space.

Correcting some things
My buddy is showing some deficiencies, might also indicate not right pH values. Should I wait for the soil to completely dry before correcting the pH or should I flush right away? Also why does it take 4 days for the soil to dry? I always make sure she drains every time.

American Cookies 1st grow - Nutrient Deficiency fixed? What about my LST with budclips?
What’s up? Updates on my previously unfed American Cookies: Looking better IMO, what do you think? Is the lack of nutrient fixed? I also did an LST with budclips on it to help utilize the space a little bit better, did I do it right?

Nutrient lockout?
Having a problem with bottom leaves turning yellow and dying. Starts off with brown on edges and tip, then leaf yellows and dries up. Potassium deficiency? PH problem? I flushed plants yesterday with 6.5 ph water and sledgehammer flush from fox farm. Pictures on week 10. Thanks!

Yellowing leaves.
Yooo! I have a few lower leaves starting to yellow I’m pretty sure its because the plant has switched all the energy to bud production so my question is, is it ok to defoliate the yellowing leaves at this point?

Yellow-ish leaves and brown spots
I ran into a small problem. The leaves of my RQS Critical are getting quite yellow and brown spots appear on some of the leaves. PH is kept between 6.1 and 6.5 while growing in organic soil. I feed according to the BioBizz schedule. Curled leaves have already been fixed.

Is this nutrient burn and should I be LST’ing or just let it veg freely?
Wondering if the yellow burn and brown burn are from nutrients or from lighting? Plants seems to be doing fine. Is the smaller of the two. Left plant , I LSTd. Just wondered if it is too much?
