That's light stress for sure you can tell by the top of the buds too. Just raise the light. 👍🌱

Leaf damage/discolouration
The yellowing is from an earlier issue but now I'm noticing brown spots and the leaves curling up, some getting crispy-ish. I recently lowered the lights a few inches, knowing I was pushing the safe limits. Is this from the lights or is more likely a nutrient/pH imbalance?

Too much light or other deficiency
Too much light or some other deficiency? I’ve been having some issues with yellowing leaves and some other issues with browning and wilting/curling which I thought was initially nutrient lock but what I noticed is all four plants were not stunted and continued to grow normally.

I have started the first week of flowering with Grotek fertilizers, pH 6.4 and EC 2.83. My plants, after 2 days, look like this, so the soil might be dry when checking..

Some brown spots showing on the top sugar leaves. I suspect it is due to the cooling fan of the light blowing down hot air? I've adjusted the fans to blow air directly over the top of the main cola's and I increased the light distance.

Pest attack. What can I use to eradicate?
3 weeks of flowering, and the pests are still here. Can I play Beauveria Bassiana? Or just neem oil? - The temperatures were very high here, exceeding 30°C, this week it will decrease. - I have other plants to harvest and I'm going to take advantage and clean the grow. Help 😥

Tache cuivrés sur feuille.
Je me demande si les tâches cuivrées sur les feuilles de ma plante de cannabis et d'autres plantes sont dues à une carence en calcium ou en phosphore/potassium. Les feuilles affectées sont généralement les grandes feuilles, souvent nourricières. Voir agenda. Je vous remercie 🙏🌱

Brown spots and yellowing
What do you think this is? Nutrients deficiency or maybe soil ph. Happened overnight and the plants are a little dry but I just gave them water and nutrients. My ph tester has been broken so I’ve sorta been winging it with some ph strips.
