Plants are now what appears in Week 4 of flower, even though the natural light cycle is still above 14 hours per day. It’s likely that the streak of cloudy mornings over the past couple of weeks has contributed to the transition by simulating shorter effective light periods.. that in addition to going from indoor to outdoor
Nutrient Activity:
• Started the week with a cap mag-only feeding to address ongoing signs of magnesium deficiency.
• Later in the week, applied a strict Epsom salt feeding at 1 tsp per gallon, one dose per plant.
I also moved my watering schedule from late in the evenings too early morning and midday to address a potential cold shock.
Observations:
• Minor yellowing remains present, particularly in the older leaves. Still leaning toward a magnesium deficiency as the primary cause.
• Toward the end of the week, tip burn began to appear, likely due to nutrient buildup from trying to aggressively correct the deficiency.
It’s a delicate line right now between resolving deficiencies and avoiding overfeeding.

Next Steps / Adjustments:
• Reduce feedings to no more than twice per week going forward to minimize the risk of nutrient burn.
• Monitor new growth and bud development closely for any signs of stress or improvement.
• If tip burn continues or worsens, consider a mild flush to rebalance the root zone.
If the yellowing stabilizes and tip burn is contained, I’ll resume light feeding adjustments in the following week.
