4x8 Mixed Photoperiods

A good week and the girls have gotten much bigger, some signs of deficiency has shown but it wasn't severe. The lightening between leaves went away after the bump in nutrients, It's our first soilless grow and i'm guessing either magnesium or nitrogen. The only signs the remained were on a bottom leaf on Apex and i'm leaning towards it was magnesium. I cut the doses from the calculator in half for each feed as I feed every watering 2-3 times a week. Instead of a full half cut though, the additives remained full strength of 2ml per L and the Advanced Nutrient calculator wanted 3 ml of Micro, Grow and Bloom for week 3 of Veg but instead of half of that, I went with 2ml per L which is a little more but I didn't want to stray too far from the calculator with the signs of deficiency. Theres some signs of burnt tips so I don't want to do the full Week 3 dose and worsen it. it doesn't seem bad right now. Currently we only have a Vivosun TDS meter and can't get another for now so I will watch them closely, we think it's reading wrong after the last grow and I'll check it in distilled water soon. The PPMs read high with a full week 2 dose of everything, initially reading 1300-1400 PPM, but after a half hour or so it settles to 1000-1050 PPM even if I stir it up. From what I've read that can be a little high. The E.C at first is about 2.5 up to 3.0. Once settled it's around 2. Transplants to their final 7 gallon fabric pots came on the last day, and took hours we were exhausted please pardon the mess I cleaned it after of course lol. We can tell the plants like the Promix BX with perlite but transplanting was difficult. They were partially damp, not freshly watered and not dried out but the only ones that were the easiest were 3 who were nearly root bound. We hope to go organic soil next run. Instead of lowering the light further this week we kept it at 30ish inches and left at 60 percent dimmness while they recovered. The following day we will bump it to 80, followed by 100 percent light towards the end of the week. Topping will most likely be done towards the end of next week as well and some LST work.
