Grow #2: Strawberry Cheesecake, Lemon OG

Cotyledons of both seedlings greened up as hoped. First set of true leaves appeared by 4/8. I fertigated once with the megacrop, kelp, calmag, and Floralicious plus at 150ppm on 4/8. On 4/11, the true leaves had started to twist slightly, a sign of early calcium deficiency. added more calmag to 400ppm and 1tsp of Real Growers Recharge to the existing solution, and fertigated. On 4/13, the true leaves had less twisting, but had started yellowing a bit. Switched up the methodology a bit, as it seems I'm starving my girls a bit. Moving over to daily, light feedings. Keeping it simple. Feeding 50ml to each of 1/4 tsp/gal (200 ppm) MegaCrop, plus 1/8 tsp/gal of Armor Si (Silica supplement). pH to 5.8-6.0. Additionally, to make sure the calcium deficiency doesn't come back, I lightly foliar sprayed with 1/2 tsp/gal solution CalMag. It looks like they've not been slacking in the root department though, because a root can be seen peeking out from one of the drainage holes!
