Yellow tips please help my babies.....

[whatsyourpoison]

Hey guys i was just wondering if anyone would be able to give me a few tips about what problems my plants might be facing. There are 2 photos that i attached that will hopefully show the problems fairly clearly. My plants have been generally pretty good and have been growing fairly well unitl just recently when the tips of the leaves started to turn yellow and curl up. I have been reading about some things and i think it might either be (N) deficiency or that they are burnt from too much heat/the lights being to close. Any help that you guys could give me would be awsome as this is my first attempt at home growing and am eager to learn all that i can to help maximize the fun stuff :jointsmile:

Other way around; that's probably a N overdose. Other possibilities to show that leaf shape are not enough ventilation or too little useable root space for the size of the plant (this includes if you are overwatering your soil into a mucky mess at the bottom fo the pot).
Fill out the troubelshooting form for more help, but next few waterings, give jsut water, and make sure your soil is drying out pretty well in between.

Hi whatsyourpoison and welcome

At first glance it looks like Nute Burn.

Fill this out for better input.

Thankyou for the welcome guys and also for the quick replies. So i'll stop nut and water with straight water and also perhaps water a little less. Once again thanks for the advice and il be sure to let you know how i go.

No no... not just that! Fill out the form so we can be 100% sure that your problem is from N overdose, because trying to fix something without positively identifying the problem can lead to MORE trouble!

Looks like you could use some perlite in your mix, too. A little late now, but next time you transplant...
