HELP! Leaf tips yellowing - excessive nitrogen?

[kobe]

Hello Growers,

hope all you doing fine. I need help - I'm at flowering stage and my leafs seems have a problem. They are starting yellowing from tips. I'm growing in soil and using 100% Terra. I would say there is a problem with excessive nitrogen.. What is best way to heal my flowers? It looks like they stopped growing.. Thank you for help.

Best regards.

Doh! no photos are showing. Nitrogen burn doesn't always relate to tip burn, generally that is a sign of excessive nutrients overall. Excessive nitrogen usual shows as dark green leaves and clawing downwards of leaf tips. If you can upload a pic of the whole plant, that would be helpful. What are you feeding it and do you measure the ppm and Ph before you feed?

At last post there were 5 days old photos. Actual photos are here. What do you think guys? Right now I'm flushing with 6.5 PH water.

She definitely looks over watered, but with your flush, that makes sense.

The burning on the leaf margins can be a few things. It could be a potassium deficiency, it could be that the humidity is low and the soil rich which in that scenario, the low humidity makes the plant drink fast but it is drinking some loaded water and quickly transpiring through the leaf margins. Another similar scenario is if you have a strong fan blowing directly on that area of the plant. If the plant has stopped growing and you only see the problems on the new growth, it may be an immobile nutrient causing the problem.

Be sure that the soil Ph is in the proper range, otherwise attempts to correct nutrient problems will be less effective. Adding the 6.5 Ph water is a good measurement to be at. Do you use any sort of cal/mag with your feed?
