So, I have made quite a bit of mess ups in this grow so far... I overwatered bottom right in the beginning and made it very yellow, I just figured out that I have been overfeeding my plants a lot (about 2400ppm most recent feeding), which was the ppm range for a 700 scale, but my meter is a 500 scale, didn't even know what that was until now. I have fimmed all four of my plants once, two on the fourth node and the other two on the fifth node. I have had my light on 25% for the whole 4 weeks and just turned it up to about 60% early December. My plants are starting to get yellow on the bottom and I noticed one looks a little burnt on the tips. I would greatly appreciate any help!
