Si es una auto y estas en la semana 8 de floración, yo diría que es el propio ciclo de vida de la planta, que esta llegando a su fin. Si no recuerdo mal, esta cepa auto necesita 10 semanas desde germinación.

Moist build up at bottom - overwatered I believe this seedling had too much moist. The soil was moisty when I filled the pot. Somehow the pot feels very heavy now and seems there is a build up at the bottom. I made some airpockets to the bottom. Should I wait or take it out and put it into a cup and dry the soil?

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?

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?

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

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.

N issues This girl suffered from N deficiency very early. So I gave it nutes. Nutes gave it N toxicity. So I flushed the soil with ph’ed water. You guessed it, it’s lacking N now. The problem is the pot is still very yet and heavy so I don’t know if I should water with nutrients

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.

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?)

How’s she look? Green enough?She got a heavy defol almost a week ago. I’ve been working my nutes and afraid she might not be getting enough N. She’s been under the new light for a week too. Is it just stress or is she missing something? I’m thinking about balancing my nutes back out and upping some calmag.
