Leaves getting yellow and rolling up
MisterZstarted grow question 3y ago
Hello. I noticed this morning some leaves have their ends getting yellow and roll up to the center of the leaves. Some other leaves have very tiny brown dots. Only one plant shows up this phenomenon, others are ok. Ph is 6.5 for watering. Any ideas? Advice? Thanks for helping

Sieht für mich nach zuviel Wasser oder falschem Gießen aus. Darauf deuten die Krallen (die nach unten gebogenen Blattspitzen an den grünen Blättern) hin. Die trockenen Blattspitzen zeigen Zeichen von zuviel Dünger (N). Könnte aber auch an der Wässerung liegen, dadurch sammeln sich Nährstoffe am Topfboden und so kann es auch zu Überdüngung kommen.
Am besten du gewöhnst dir einen festen Rythmus beim Gießen an. Faustformel: immer nur soviel gießen, dass die Erde spätestens nach 3 Tagen wieder vollkommen trocken ist.

I confirm I was out for some days and watering was quite erratic. What should I next? Water as usual or do something else?

Yellowing Budsights Early Fower (organic grow)I fed the plants yesterday and noticed that it was too warm in the tent. (86F)
So I change the light time to 9pm-9am.
As a result, the plants had 24 hours of darkness in the tent.
When I turned on the light today I noticed that some of the buds had yellowed.
pH (soil): 7,8-8,4Buds. Other

Temps have been mid 70s and humidty mid 60s. Picture of the smaller plant is about a week younger than other plant.4y ago

What deficiency is this?Earlier, I added Epsom salts to fix purple stems, I’m pretty sure I over did it and I think this is a potassium deficiency but I’m not sure. I was being cheap and didn’t change res b4 moving over. Now that they moved tents, seems to be getting worse. How do I fix fast!? Pix in di6y ago

Discoloration and burnt edges on leavesCan someone please help me diagnose this problem?
At first I thought it was root dry spots from the drip watering system but it’s gotten worse.
The bottom leaves are yellowing and the edges are burnt with a hole in one of the leaves.
Anything helps, thanks!Leaves. Edges burnt

Underwatering Issue or something else?I haven’t been tracking exactly how much I’ve been watering. I usually water until run off. I’ve had to water daily because the coco loco has been drying out quickly. Is the yellowing seen in photos from 4/28 due to underwatering?
I’ve been pHing between 6.2-6.4Week 4

Correcting some thingsMy 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.Leaves. Color - Yellow

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…Leaves. Color - Yellow

Lower leaves turning yellow and getting crispyLower leaves are still turning yellow/brown. See photo. A couple weeks ago I got a greenhouse to protect the plant from the rain. Outside temperature has been lower and there hasn't been much sun (mostly clouds) so I don't think heat is a problem anymore. Don't know the pH. Help!Week 5
