Growing from seed Tweed Bakerstreet (Indica) April 2019, outdoors in coco coir, weekly nutrients, sunny location, lower leaves yellowing- nitrogen deficiency? Too much sun/heat?, no sign of flowers, any idea when flowers will start producing? Thanks so much for advice for this new grower

When the days get short enough (September/October?). Next time, try a couple autoflowers. The nice thing about them outdoors is that they're on a fixed schedule. You can get a couple harvests in the summer while waiting for a photosensitive to make it to Fall.
Since you're not growing in the ground, I would shade those soil containers. They can get hot in the sun. The concrete they're sitting on can get hot too. (You might set them on a 2-3 layers of cardboard, or cardboard with plywood on top. You get the idea.).
When you feed, do pour enough to get runoff? If so, do it in a saucer (or something) to collect the runoff, and use a TDS meter to measure the ppms. I'd be inclined to feed stronger. But, I'd be reluctant to do that without seeing what the runoff ppm is. (For me, that stage of growth, I'd be seeing 900-1200ppm.). In early flower it starts going higher. I try not to go higher than 1800. If it hits 2500 I have lockout. So, I definitely start feeding lighter at 2000, and more runoff to "flush" out the buildup. If I were underfeeding, the runoff ppms would be 400. (I don't know if these numbers are specific to my soil/nutrients. I'm not sure they apply to you. I've seen it apply to a couple other people.).

The ppm varies from strain to strain and even plant to plant. Just have to watch the plants to see what they like. Some want much higher numbers some prefer lower. The breeder can usually tell you where a certain strain likes to be on average. Can always start there.
But it does look like nitrogen deficiency. Do those yellow leaves at the bottom come off if you pull them lightly? If so it's for sure nitrogen deficiency. To much nitrogen will turn the plants dark green.
