Crescendo grow

The yellowing tips on this cannabis plant are a pretty common sign of nutrient burn, which happens when the plant is getting more nutrients than it needs. It’s usually caused by a high EC/PPM in the feeding solution. If this is the case, backing off on the nutrient strength slightly should help. Another possibility is light stress—if the grow light is too intense or too close, the leaves can start showing tip burn. If this plant is near the top of the canopy and closest to the light, raising the fixture or dimming it slightly might be worth trying. It’s also good to consider pH issues. If the root zone is too far out of the ideal range (around 5.8-6.2 for coco or hydro, 6.2-6.8 for soil), certain nutrients might not be absorbed properly, leading to similar symptoms. Less likely, but still worth keeping an eye on, is potassium deficiency, which can also cause tip burn. However, with a solid nutrient schedule, this usually isn’t the first suspect. - Check nutrient levels (EC/PPM) and consider lowering if they’re high. - If possible, check light distance/intensity and adjust if needed. - Measure pH to make sure the plant is in the right range. - Watch for changes—if the yellowing worsens or spreads, reassess potassium or other deficiencies. It’s a mild case right now, so small tweaks should get things back on track!
