Warum werden die Blätter auf einmal so schnell gelb und welk?
Hey, meine Hawaiian Runtz ist Ende 4. blütewoche. Gießen tue ich alle 4-5 Tage mit 2-2,5 Liter Wasser und 6,5 ph Wert, immer ziemlich identisch mit Terra aquatics ph Tropfen, also sollten ph Fehler ausgeschlossen sein. Temps am Tag ~28 und nachts 26 grad Celsius. What’s wrong?

Identifying the cause of stress
Does anyone know what I’m seeing with the leaves in these photos? The closest I’ve been able to guess from online resources is maybe sulfur deficiency, but to my eye it doesn’t seem to quite fit any of the broad categories. Perhaps just general under-fertilization?

Brown spots on the Gold Leaf?
Brown spots with light yellowing. Possibly calcium deficiency? This is only happening on the Gold Leaf. Neither of the GDPs are showing these signs. This has happened over the last 2-3 days.

Burn leaves? Yellow leaves? BIg problem? (AUTOFLOWERS)
I had a problem with a lack of magnesium in the larger plant and I applied a little with a sprayer directly on the leaves, I got confused, I sneezed once on the leaves of the smaller seedling. Can I do something to resolve it? I even thought the LED was too close and I raised it

Yellow Leaves Autoflower
Novice grower, Outdoor. Started in a 70/30 coco-coir to perlite mix. Forgot Worm Castings until 22nd June, implemented with top dressing of Gaia Green Power Bloom and All Purpose. Overwatered at stem for a week or so. I suspect it's either an N, P ,or K deficiency (nuteburn?)

best leaf insects repellent
I have found a few bad insects on my plants past weeks. Does anyone have experience with neem oil? Is it worth a try or would I be better of buying something else? White vinegar with dishsoap didn't help much. The bugs are: grasshoppers, stinkbugs, spidermites & fungus gnats.

Yellowing on leaves tips. Should I start feeding her?
Some yellowing appeared on the leaves this last day. Temps and humidity are controlled and ok. I haven't been feeding her, she has been growing on light mix for the past 25 days. Im thinking its time to start applying some nutes. Or could be something else? Thanks!

Yellow spots on leaves
Are the yellowing spots signs of Leaf Septoria? I'm assuming it's more of a nutrients issue but have never experienced LS and wanted to get some second opinions.

Leaf tips yellowing. Overwatering? Or nute burn?
I recently flushed my soil with water that was PH 7 (my soil was a bit too acidic). My question is: are the yellow tips and browning due to the overwatering from the flush? As well as stripping the soil of its calcium? Thinking of giving them 3-4 days before watering with calmag

Hello guys, some leaves are yellow, it's only 2-3 leaves in the middle, middle low part of the plant.Yellow at the end of the leaves and green at the base of the leaves, it's subtle thing but I'm afraid it will worsen and spread over time

The leaves are yellowing, some are turning purple.
The leaves are yellowing, some are turning purple, maybe it's normal or maybe not, I don't know. If anyone could give me some suggestions. I decreased the light intensity to 75% because unfortunately I can't raise the lighthouse.

Feeding
How often am I meant to feed and water my plants. I do water my plants every 3 days and after every three feeds I flush. Concerned as all the bottom leaves in my grow are turning yellow but the tops are okay. I do give them Calmag so I’m not sure what the issue is here.
