🌿 Lettuce

Lettuce just got checked.

Most likely diagnosis

Normal lettuce regrowth after harvesting outer leaves, with mild stretching toward the grow light

Your lettuce looks generally healthy. In this setup, the plants are behaving like cut-and-come-again lettuce: the outer leaves can be harvested while the center keeps producing new growth. Yes, they can keep getting taller, especially if the light is a bit far away or they are stretching toward it. The light being raised because the leaves touched it is a clue that the plants are simply growing well, though the lower plants may be stretching a bit more than ideal.

Keep harvesting outer leaves and keep the light close enough

You probably harvested them correctly. For lettuce, take the larger outer leaves and leave the center growing point intact. Keep the light adjusted so the tops are close enough to avoid stretch, but not touching.

Harvest only outer leaves or whole outer heads, leaving the center intact

Lower the light if possible so the canopy stays close to it without touching

Rotate or space plants if some are shading others too much

Differential diagnosis

Also possible, but less likely

Light is slightly too far away, causing mild stretch

Harvesting may have removed outer leaves correctly, but the plants may soon be past peak baby-leaf stage

If older inner leaves start yellowing, it could be mild nutrient depletion in the reservoir

Targeted checks 🔎

What would prove it

Look at the center crowns: if new leaves are emerging there, the plants are still actively growing

Check whether stems are getting long and thin; that would suggest light stretch

Watch the newest leaves: if they stay compact and green, the harvest method is fine for cut-and-come-again lettuce

Next expert check-in ⏰

Next 1–2 weeks

Decide whether you want leaf harvest or full-head harvest

If you want ongoing harvests, continue taking outer leaves. If you want denser heads, let one or more plants grow without harvesting much and see whether they bulk up from the center.
