2nd Grow - Afghani #1 & Gigabud

Transplanted into 3 gal fabric pots a on 11/7 into coco coir plus perlite with 2 Tbsp/gal Dr. Earth 4-4-4. I also watered with a fert tea using Dr. Earth 4-4-4 and liquid seaweed on 11/7. Both plants are looking a little light, and the Gigabud looks like the lowest leaves are yellowing. Last grow I had some yellowing starting to show around this time, but I thought it was due to the poor soil mix. I may just need to use a higher strength mix of the Dr. Earth dry amendments from the start. *Plants have stopped yellowing and new growth looks very healthy. I do think that the problem is light fertility in the seed starting mix. A higher dry amendment rate or fertilizer tea starting earlier in the grow would probably help. Each plant was watered daily with dechlorinated tap water pH'd to 6.1-6.8. The plants are up to 750ml a day with no runoff.
