Hello all,
I am trying my hand at growing a few plants indoors and noticed some recent changes I thought might be a problem. As you will see from my photos, some of my leaves are turning brown/yellow and the stalks are turning red. Is this something to worry about?
I started these seedlings outdoors, and moved them into a tent last month. I am watering them every few days, only when the soil feels dry. I’ve been using Arber Plant Food every couple weeks. My tent has an outtake fan/filter and inner fan. I’ve been keeping the temp at about 70 and humidity around 60%.
I read that the reddening stalks is due to the plants being too close to the grow light, but my light is at the very top of the tent (60" high). I’ve also got it set to the second lowest brightness. The light is on an 18 hour timer as I heard that is what is necessary during the vegetative stage.
Any advice is greatly appreciated. Thank you!
There’s great advice here in the thread already. But I’ll add a question: are you checking the pH of your fertilizer solution?
If your pH falls out of range, it can cause the plants to show similar symptoms due to the nutrients no longer being absorbable by the roots
Thanks, I do have one of those ph/water meters which says its fine but I heard those devices are kinda shite.
