Whats happening with my plant?

[Wakenbaker]

I'm new to growing so bare with me. I have a young plant that I'm growing indoors. Recently I've noticed some burnt edges on a couple leaves. I've checked the soil ph and its right at 7. Reduced the amount of fertilizer and tried flushing with water. Included some pics so everyone can see what I'm talking about. Any help would be greatly appreciated

Humic and fulvic acid supplements? Or just soil and water?

Just soil and water. Did use some miracle grow quick start when I transplanted from seedling pot to bucket. Organic peet moss and compost for soil. Water is slightly hard but not bad. Ph levels are right at 7 for soil and water according to my electronic testers.
