White Tips on my Leaves

Here are my stats:

Indoor Grow - 5 Gallon Buckets (w/full Drainage).
Medium - Happy Frog Ph’d soil.

Strains - Grand Daddy Purple Auto ( 2 weeks old)
Banana Kush Auto

Lighting - Electric Sky
Humidity - 67 - 73%
Temp - 73°
Ph - 6-7

Cal Mag Plus - 1 Tsp
Fox Farm Grow Big - 1 Tsp
Water Ph’d to 6-7 after Nutes mixed (Per Gallon)
Soil Moisture Level (Measured Green)

So after some research it seems that White Tips on your leaves indicates the beginning of Nutrient Burn. So as an immediate response I flushed twice with Ph’d water and have seen no improvement.

Should I re-start adding Nutrients, but at lower amounts now or keep flushing?

Any Ideas?

Yah it maybe nitrogen def starting what type of light u running and what height is at

Electric Sky lighting dimmed at setting 4 according to the manufacturers setting chart.

Lights are set at 24 inches.

I also have been monitoring for signs of excess light and there is no curling or cupping.

The nute burn is very minimal. After the flush you need to get back on the feed schedule. Overall you’re plants look good. :+1::v:


I would resume feeding as well, maybe start half dose to start with and bump it up from there, happy growing

also, when you say your ph is 6-7, that’s a large range and makes me think you are checking based on the shakers where you fill up a vial with your feed and drop some liquid and read the color chart. if that’s the case, this is very inaccurate. you should know exactly what your ph is. check out the apera ph20

No, I have been doing this for three years, I’m not that unsophisticated.

I use the meter and everything :crazy_face:



Upon a much much closer look it appears that most of the tips have twisted at the ends.

Also, I have one plant that is showing brown spots on the fan leaves here and there.

I flushed and adjusted the Nutrient level in half again.

So feeding every three days and Ph’d water in between.

I can’t figure this one out. I believe that I’m taking all the necessary steps
to avoid the Burn, but am believing that something else is going on here.

I wonder if the experts on this site could chime in.

The PICS above are perfect examples, Just zoom them for close-ups.

Thanks. :slightly_smiling_face:


This condition seems to be spreading, but all research leads to a nutrient issue. So I was feeding every three days.

Since these are auto flowers, they are at the beginning flowering stage.

Can you under feed your plants and get the same symptoms??

I thought it might be environmental since I was seeing it everywhere, but everything about
white tips reveals a nutrient imbalance.

So I am now feeding every 5-7 days and half the suggested amounts. I water with ph’d water in which I usually have to ph down from out of tap. I usually get in the middle of 6-7 on the scale.

I also noticed that watering them once a day is barely keeping them in the green on moisture content and will be adjusting the watering schedule up a notch to keep up. (Yes I use fancy meters to measure my water’s ph and soil moisture and ph levels as well as EC).

So EXPERTS. What am I doing wrong or not doing??

PLEASE Help before my plants suffer anymore if you realize what the problem is.


In addition, Since flowering has started I am supposed to stop the CalMag so my Nitrogen levels don’t spike and cause issues.

Can we confirm this research?

Did you ever figure this out?

I’m having a similar issue.

There are a variety of causes for your plants whitish or yellowish tips, the most common of which are nutrient deficiencies.
