4 AK-47 Automatic in 3-gallon pots with 100% coco coir using technaflora recipe for success watering with 50% strength nutrients on every feed. The nutrients are added to my tap water which is around 185ppm.
So a few days ago I had my first leaves on the bottom of one of the plants. I didn't think too much of it as these are on day 35 so now well into flower, but now two plants have yellow/dead spots, one around the middle on a fan leaf and one on the very top, and also general yellowing at the bottom in an uneven manner.
Am i correctly diagnosing this as a Magnesium deficiency? I had actually already prepared my next feed with 1tsp/gallon Magical (Technaflora CalMag equivalent) as opposed to 0.5tsp. Will this probably fix the problem? I still have around 30-35 hours until next feed, so any help before then would be great.
