Yellow tips of leafs …

RockSta83started grow question 2 months ago

Overfeeding? Yellow tips starting on top of the plant … should flush or just wait and reduce the feeding next watering? I‘m entering the pre-flowering stage and would normally start to add bio bloom and top max with the next watering …

It's a bit too much nitrogen but nothing bad, I can tell from the dark green color and some tips starting to bend downwards. They don't like a lot of N when they start to flower. But don't need to do anything about it just stop feeding N

Yellow tips do hint towards an excess of nutrients, usually Nitrogen. As long as it's just the tips, there is usually no reason for concern. It's simply a sign that your plant is on the edge of what it can uptake and process. So no worries. No need to flush. Keep going as you were, but don't increase the nutrients you are giving already, especially nitrogen! You should be good to give BioBloom and TopMax. If it's her first dose, perhaps start with half-doses so you don't push her into stress trying to process everything at one time. Hope this helps, even a little!

Nutrient burn or light damage?Burnt tips appeared around week 3. I think the bio tabs are a bit too hot for this plant. The plant is growing at a good rate so I don't think a lockout is occurring. Burnt tips across most of top of plant. Could this be light damage? How to proceed or do I even need to worry?
