Hey guys, my white widow fem plants are about a month old now, and growing pretty strong. I accidentally overfed them a couple days ago and right when I saw the yellowing tips I flushed the whole system out and refed with about half strength like I have been previously. I am growing with just generic potting soil mixed with perlite, the soil isnt prenuted, feeding with miracle gro tomato food. After I flushed there are brown spots showing up on my plant that are slightly getting bigger as of today. I was wondering if it was a deficiency due to the large flush I just did or if it's still an effect of the overfeeding that I did? Also the ph is a Tad high at about 7.2.. Idk if that could be the problem or not? I've been trying to lower the ph with lime juice mixed in water but any suggestions would be appreciated as to an effective way to go about lowering soil ph! Thanks! Ps. I am growing with a 180w apollo horticulture led light that is about 12 inches from the plants.
