3 possible reasons. 1. This plant wants more nitrogen or ph levels are slightly too high. 2. This plant is more sensitive to light and doesn't like it being so close. 3. This plant has red /purple genetics and a different "pigment" 🌱👍🌿

CalMag issue. If your giving them enough nitrogen (talking about BioGrow) then this is definitely a calmag deficiency. 😎

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?

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

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.

drooping leaves, cold weather and high humidity, is it overwater problem?I think i´ve overwatered my plants, so it´s is cold (16 C / 60 F) and relative humidity around 70%-75% . old leaves are turning yellow. I´ve lowered the water frequency and wait the soil to dry before water again but leaves are still droopy. What do you think? is it overwater?
