I had what appeared to be a magnesium deficiency a few days ago, using Dyna-Gro nutrients, and after having trouble with pH, I decided to switch back to General Hydroponics; this looked much better, but then today I noticed some serious leaf curl on a few.




The first two are the two with curling leaves, the second two are showing damage from last time.
2.5 gallons R/O
7.5ml Pro-Tekt
20ml FloraMicro
40ml FloraBloom
7.5ml CalMag+
2.5ml Floralicious Plus
pH: 5.9 (has risen from 5.7)
Air temp: 78F
Water temp: 68F
All that comes to mind is that perhaps they were still a little deficient, and I didn't compensate for that when refilling the reservoirs; I'm probably going to hit them with a foliar, add 2.5-5ml CalMag+, and this microbial tea which pretty much literally just finished brewing.
I did notice a little brown on the roots of some plants, but not the two in question, and it came off by simply swirling them in the nutrient solution; I'm betting it's probably from the Floralicious, but either way the tea should take care of it.
