Hi there Grileon, that's classic Mg deficiency, that's exactly how it looks in a text book. Normally you always want to be adding calmag to the tank. One more thing : i see some N toxicity happening, especially on the plant with the "dark green" 'shiny' leafs. You might want to fix both issues as soon as possible. Hope this helps ! 🚀
KushGANGanswered grow question 3 years ago
Hello agree with Dasboof you have a nitrogen toxicity which the dark shiny green is characteristic. Then for your brown spot it is calmag deficience due to a high EC in your soil. So to correct calmag use epsom salt which is the best way to correct it. You can use it in the soil or in water. More you can mix in water and mist your plant with it for a quicker effect. Good luck. Bye

Plants are burning part 2Added some Bud Boom (0-40-23) to give a kick of phosphors…. Most of plants are turning yellow and burning that’s problematic !
What’s about phosphorus with my watering ?
Maybe Cal-Mg?
Or even are the roots to compact on the bottom of the pot ?

Found something weird on my new leaves. Need an expert's opinionFound something weird on my leaves. I need an expert's opinion and insight. I don't know if it's natural to occur on newly developing leaves or if it's an issue that needs to be addressed. I'm thinking it might be natural but it seems weird to me.

Do these burnt edges look like heat stress or a nutrient issue?I noticed this browning on the edges of two fan leaves this morning. The affected leaves were right next to the space heater that runs all night (cold basement!), so I *think* it’s probably heat burn/stress. But don’t want to ignore a potentially more serious issue. Thanks!
