Quick yellowing problem

[Jaden4306]

In the end of the 5th week of flowering. Yellowing started a few weeks ago and just moved it's way up. When I started the flowering stage I realized I didn't have Cal mag and boost when it was scheduled to be fed. I had to skip a feeding until I can get the nutrients I needed. Started feeding them all the nutrients during that next feeding. I feed, water, feed. My temperature is 76-78° and humidity is 43-51%. I just watered today with plain ph water. My runoff ppm was 1012. I did a soil slurry test yesterday and the pH was 6.3. still new to all this and need help before I loose this plant

Are you growing in soil or coco? What are you feeding your plants?

Soil. I'm using lotus powder nutrients

Based on where your plant is in the grow cycle and the yellowing leaves started at the bottom and have moved up, It looks to me like a case of nitrogen depletion, and maybe some potassium depletion.

Don't reduce your base nutrients. I'm not familiar with Lotus nutrients but check the N and K levels in your base nutrients. In the 5th week of flower your girl is also likely looking for more potassium. I don't think you are seeing a 'fade'. Based on your environment numbers, PH, and runoff PPM your environment is good. Don't change it.

Add the cal/mag supplement but don't go overboard, and watch your plant.
