Hi
@AxemAll The plant is experiencing a classic case of nutrient lockout rather than an actual lack of food. FoxFarm Happy Frog is a rich, premium soil, and adding Tiger Bloom (which has an NPK ratio of 2-8-4 and is highly acidic) likely shifted the root zone environment.
When a concentrated bloom fertilizer is added, it can drop the soil pH suddenly. If the pH falls below 6.0 in soil, the roots temporarily lose their ability to absorb key micronutrients like magnesium or zinc—even if they are sitting right there in the dirt.
Action Plan to Fix It
1. Check the Runoff pH First
Before adding any more supplements, water the plant with plain, un-supplemented water adjusted to a pH of 6.5. Collect the water that drains out the bottom of the pot and test its pH. If the runoff is below 6.0, the root zone is too acidic.
2. Perform a Light Flush
If the pH is too low, flush the soil with 2 to 3 times the volume of the pot using plain, pH-balanced water (6.5). This clears out excess salt buildup and resets the root zone back to its ideal comfort range.
3. Introduce a Cal-Mag Supplement
Once the soil pH is stable between 6.2 and 6.7, add a standard Calcium-Magnesium (Cal-Mag) supplement to the watering schedule.
Magnesium is a mobile nutrient, so providing it at the correct pH will allow the plant to quickly pull it up to the new growth.
Make sure to double-check the physical labels on your fertilizer bottles to confirm the recommended starting dosages, and always verify your pH meter is calibrated accurately before testing your runoff.
