Yes but a soil ph check would be my first thing to look at. Make sure you are in range. Nitrogen level is a little heavy.

On Week 11 Day 74, I've been noticing the leaves turning yellow. I'm assuming because we're getting close to harvest, but after reading more about nutrient deficiencies I'm wondering if I should be doing something about it. I started flushing a 1.5 weeks ago.

Natural or Problem?Is this natural yellowing or is there a problem? pH to 6.3 and runoff is 5.7. The stem is awfully purple, watering/feeding is where I struggle. 1st pic - 4/21 and 2nd pic - today(4/24). Seems to have escalated over the last few days. Do-si-do auto about 10 weeks.

Leaves changing colourWhat’s wrong with this plant? Put her in manure instead of soil, just read John innes and thought yeah that’s fine 😂
I’m thinking it’s holding water more than it should or else it’s a PH issue. Help please? How do I fix it or stop it getting worse?
