Hi guys, I hope somebody can help. The tips of the newer grow is getting yellow. First, I thought it was a bit light stress but I hang the lights higher up but the problem continues to get worse.
Please help
Too much feed mate
As the plant comes into pre flower more. It'll show any overfeeding were it wouldn't in veg.
450-600ppm cote NPK feeds. Once every 5-6 days with soil.
Feed enxynes and low NPK EC as subs. Enzymes or something to help follow up to break down your weekly feed.
Looks like nutrition burns. The fertilizer is concentrated too high. Esspecailly with 'mineral' fertilizer that happens very fast.
Try to wash your substrate with water (maybe even destilled water) and make sure to track your pH and ec.
Cheers💪
Look like the tipos are starting to burn from the nutrition being too high.That and the leaves being very dark would suggest the strength of the nutrients is too high.
