• Any ideas as to what these brown spots are? I am using mother earth 454 all purpose soil ammendments only. The leaves, for a bit, were showing the signs of what I thought was a magnesium or sulfur deficiency, (it looked like intervainal chlorosis) so I gave them epsom salts for 3 or 4 waterings. I realized the soil ph was very low so I stopped that and have been giving them plain ph’d tap(250ish ppms) They appeared to gain color back. Now, a couple weeks later, they are doing this. I can only assume that it’s either a calcium deficiency, or possible lockout. I have NOT given it any calimag yet. (I wanna though👉👈lol) Out of the 3 plants I have, the taller 2 are going through this, not the smallest one. So I was thinking, maybe, since they are at a different stage, and bigger, it’s most likely a calcium deficiency. The picture with thw bright yellow looking tips, are actually rust color, not yellow. It didnt show up well under the light.
