Hi, My lettuce seem not be hearting, but growing straight up like little trees. Is this right? First time vegie gardener!

When the root temperature of lettuce gets to 23 degrees the plant bolts - goes to seed. The plant does this as a survival mechanism. Something like, "Ouch, it's too hot! Quick, produce seeds before I die so my offspring will have a chance to grow in the future". That's lettuce. True also of coriander. Mulching the ground will help. Shadecloth will help. Taller/established plants nearby casting shadow is arguably best - see permaculture for design tips.
