Hey Jesperado... you don't have a diary going for this grow! Any answers you get are therefore going to only be guesses and I'm guessing nitrogen toxicity... But I don't know what you're feeding or in what amounts.. Do yourself a favor and start a diary for this - that way, it helps us help you!
Good luck!

yeah it does look like a nitrogen deficiency (yellowing) as well as the beggining of a potassium deficiency (brown spot):

Buon giorno weed doctors, did anyone have similar uniform chlorosis at the top or maybe knows what's up? What could be the reason and the solution? ThIs this some sort of immobile nutrient deficiency or excess? Could this be caused by heat and light stress? She is 80cm tall and almost touches the lights in the tent. I'm usually suffering from Calmag and Nitrogen issues and haven't yet experienced yellowing from the top. Thanks

Advise to flush or feed in VegDoes this is look like a nute burn, deficiency, or ph problem? The two plants that are growing a tad taller have had yellowing tips some curling downward. Don’t want to overreact and cause it to worsen, they’re looking healthy otherwise. Any advise whether to flush or feed?

Should I do full flush til runoff is 300ppm?So, it is obviously a deficiency, which probably caused by a lockout. Will the full flush solve it?
Yesterday I fed her a full dose of flowering nutes. Including K. It didn't change much. Lower fan leaves continue to go yellow.
Today 3L water, pH:6.2,
runoff:0.6l, ppm:1450, Ph6.0

Thoughts on leaf symptoms? The other plant in tent is doing same thing,but plant in other tent getting similar feed not. see diaries for more picturesK deficiency? Hard to believe that can happen in 65-gallon pots.Are getting big though.New growth tips looked yellow,hit them with water-soluble K and the new growth edges seemed get green.Some toco-ing, humidity is kinda high. Too intense light(800 ppfd), not enough C02 maybe?

2 autos with crispy feeling sad looking leaves, how can I help them? (more info in diary pl & crit)2 of my autos have been growing leaves that feel crispy and look deformed. I have been watering when the top 5 cm of the soil dries, but I fear maybe I fed them too much nutrients. The temp has also been on the high side (30C 80F). What could be wrong and what can I do for them?

Leaf IssuesHey all, my almost 5 week old Moby dick auto flower is starting to show some issues in the first week of flower. She got a dose of Veggie nutes 5 days ago, and a little bit of Bloom yesterday trying to fix it. Temps have been high and humidity low, would that cause this?

Lower leaves too pale or yellowing?I am noticing the lower leaves of my Royal Critical Automatic to be much more pale green than the top of the plant.
Is this a nutrient/light/watering/lst stress problem if at all?

Yellow on leavesDay 13 leaves started to look yellow / dull on tips hasn't seemed to improve 2 days later, it is the auto soil premix I'm guessing the roots are getting close the soil and nutes kicking in or does this look like another issue?
