Can anyone tell me what the prob is here?

I have no clue why the leaf tips are burning like this.. from earlier on they went from white tips to yellow tips then burnt out and dry?? anyone have a clue? Please? Is it a Nitrogen issue?

Cheers

too much nutes

Nute burn. But towards the end of flowering leaves will tend to do that anyway.
It's one or the other...how far into flowering are you?

how much are you feeding them? like 75-100% of 2 diff nutes?

Its a normal effect in later flowering but can be corrected. Watch your nutes and your water ph and if in hydro your ppm amounts. match your nutes feeding chart schedule as they reccomend and should be ok.Not a huge issue though in later flowering as the leaves will go yellow as your nitrogen has been cut way back for flower

Hmm, I actually thought it was a insufficient amout of something, cuz i didnt think I had an aggressive nute regimen. I feed with a tea, bat guano, horse and 1/4 strength Dyna-grow nutes. didnt think it was strong though. This one is at week 7, Im going to give it another week then start the flush.
So its not a big deal then? in veg though, if you see the tips of the leaves going brown that would be nute burn as well? is that so?

Cheers

yeah no big deal. if this was a veg issue then youd look at the possible ph and ppm levels of the nutes to see if they were high and causing the nute burn. Its probably the horse or bat guano your using as those can cause burns if not watched closly when used but its not a major deal and happens like this in flower often. Your good continue with your flush plan

salt build up is one guess, flush the soile good with 3 times the volume of container,
second guess, magnesium deficency.. in which case tou can use epsom salts from the grocery store even,
or you could buy some cal/mag botanicare if it's available.

Thanks a lot Fletch. My PH is 6.5... as for the ppm I dont have a meter so cant tell you anything there. I will lower the bat and horse though, I did see the tips starting to change in early flower. (see attached)

Perstephanie, I have flushed twice already. They are due for the 3rd on friday, so they'll get one. Thanks.

Cheers
