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!
I think you are onto something with the size of the pots. I think they are 8" wide, but I just popped one of the plants out and noticed that the roots were very densely populated so I just moved one to a much larger pot. Thanks for the advice!
