Day 7 to Day 9
My plants are continuing to grow nicely and are enjoying the bright, warm, damp environment in the tent - nothing's changed there since last time, it's all very steady in temperature and humidity. I am glad we don't have a cold winter at the moment.
I gave them a spray with Epsom salts solution (1 teaspoon in 500ml tapwater) on day 8 because I my magnesium level is a little low in my tapwater.
I put about 200ml of the 0.8 EC nutrient solution on each of them today just to keep to top from drying out, before I water them properly again in a couple of days or so. I know people say you can't overwater coco but I've found that's not exactly true, not when you are putting a tiny seedling straight into big final pots.
The original Sweet Gelato Auto seems to have sped up its growth rate a little, the leaves are expanding at a more normal rate now, though the stem is still tiny. I think the roots must have started growing and at this point I am still holding on to a lot of hope for her.
The second Sweet Gelato Auto seedling was started four days later, but I would guess it is very nearly the same leaf area at this point, and it's probably about three times as tall as its sister! I watered this one in with a litre of 0.8 EC on day 7, only one day after the others got it, but it seemed like it was ready.

Day 10 to Day 13
I gave them a watering through on day 11 with nutrient solution which was 0.9 EC, made with 0.8ml/l Gro, 0.6ml/l Micro and 0.4ml/l Bloom, plus 5ml/l Plant Magic Plus Root Stimulator, pH'd to 6.2.
The plants are looking slightly rough around the edges, I think it looks like a nutrient uptake deficiency. They are a little pale and there are a few patches on the leaves. I think this could be from being a little slow introducing the nutrients, or perhaps the pH being a little high, or maybe the plants didn't like the coco being soaked through after it had been dryer for a while? Or possibly a combination of factors.
The original Sweet Gelato Auto remains a tiny-stemmed dwarf. The second one I started now has more leaf area, is taller and looks like is in an identical place developmentally, producing the third pair of true leaves right now.
