6 weeks into flowering. Tips of cola leaves yellowing?

Almost 6 weeks into flowering, and the very tips of the fan leaves on my main cola are yellowing. Like I said just the very tips of each finger. I'm not using any nutes and I water it with reverse osmosis water. Sorry guys and gals no pics it's outside and right now it's too dark.

u need sum nitrogen..get something with the npk of 5-5-10 or something..make sure the PK is higher then the N since your in flower already..it should help, keep it green.

What would the Down side be if I just ignored it?

Thanks for the quick response btw

less bud production..how many weeks does it take for this plant to finish?? if its a 8weeker i wouldnt trip to much about it i guess but feeding your plant is important bro..ye need something..just water doesnt cut it

u can get some bat guano with 10-10-20 or 10-10-10 something like that and mix it with ur water to add a little something at least..its pretty cheap

It's bagseed so I have no clue at all. How much should I add? Or would there be directions on the container?

there will be directions. just find ANY fertalizer with higher N and use it. if its something like 10-15-15 then thats perfect. if its some potent nutes like 15-25-25 then dont use full strength, use half which would make it 7.5-12.5-12.5 thats how i figure it out atleast. thats how i do it and it works for me so good luck!

yeah dilute it down no matter what in my opinion, dont use it full strength until you know how it works, also since your so close to harvest. dont want to overload your plant with nutes, make flushing easier.

he hasnt used ANY nutes at all lol so flushing wont be necessary..flushing is to get ur ppm's in your soil below 200
