2 plants, about 1 month age, both in single 5g dwc buckets. 1 300w led lamp for each plant, about 20 inches high. water (well water) temps 70-74, tent temps 74-76 (much cooler at night), seedling strength nutes. I'm adjusting ph to 5.8 every morning.
They've taken off recently and are growing nicely, but I do notice some nute burn on both plants, more so the sativa in the 3 pic and pics after. The first 2 pics are the indica. I'm surprised there is burn at all because I'm still using only seedling strength nutes, and I haven't changed the res in 3 weeks on the sativa, so there has been a lot of fresh water added and the ppm is down below 400, more towards 300. my starting water ppm is around 200.
I notice some slight curling in upper and lower leaves, and because there is nute burn also, i thought maybe there is some nitrogen toxicity. the plants are fairly dark green, nothing too outrageous.
My ph and ppm both are dropping daily, which I'm a bit confused about. The roots look really good, very white, no smells, lots of growth. I understand why the ppm is dropping, especially since I'm adding fresh water every other day, but why is the ph dropping as well? The sativa res seems to stay more stable, dropping only to 5.4 or so everyday. But today and yesterday the indica plant res dropped to 4.8 from 5.8 the day before. That is a pretty big drop, I'm wondering why it's happening like that.
I guess I'm just sort of doing a checkup for the plants. It's my first grow, a few errors so far but otherwise so far successful. Just wondering about these questions above and any other thoughts or comments that may benefit the plants.
Thanks
Edit: The bottom left leaves in the 4th pic are turned down because they are grown against black gardening plastic i'm using to keep the light out of the buckets. They aren't naturally that curled
