Well this has been a trial and error week.
I noticed a calcium deficiency so I added 5tsp/gal to each of my pots raising ppm to 1400. Stretch showed some burn after 2 days so I emptied her bucket out and did 1tsp putting her at 1100 ppm, we'll see how that goes. Thickness hasn't shown any negative effects to 1400 yet but I'll keep an eye out.
Other than that, I added 5tsp fish meal and 1tsp magnesium to both. Still looking great, looking forward to flowering.
