K 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?

Magnesium deficiency, not potassium defciency.
In soil grows, a pH of around 6.4 is ideal, 5.7 in soil is way too acidic.

Hola! controlas el pH del agua? puede que no esté correctamente y las plantas no estén aprovechando eficientemente de los nutrientes del suelo. El valor en esas semanas suele ser alrededor de pH 5.7. La fertilización no es probable que sea porque se las ve bien desde el centro. Controla los valores de temperatura y humedad, no se ve muy grave.

It looks like a K deficiency. Could be a possible lockout of K .

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. Thanks4 months ago

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, Ph6.0Leaves. Color - Yellow

Burned tips and white spotsHi, I have a auto plant in its 7th week. Today I noticed that it has burned tips. The white spots have been there for longer, I dont know if they are related to the same problem.
Im new to this and what I came up with is that the white spots could be a cal defincentcy?

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?Leaves. Curl down

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?Week 3

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?

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?Leaves. Curl up
