It kinda looks like nute burn to me. You will get some other repsones so hang tight.

I second that.

Konehead,since you are using Rodi i would supplement with some calcium and magnesium. you can use Epsom salts for this.

thanks... went to hydro store the guy said i should not worry bout couple leaves but if i wanted to give some cal/mag
so i bought bottle of that for ten bucks.i mixed 1tsp with gallon of water and used half of the gallon.so lets see if she improves

time to turn off the grow big and add some big bloom.... also a tsp of epsom salts/ 1 gal water should help...


another tip: FD's fert sched:

what i mean is that not all autos are the same lol
I have been growing the same genetic line for over a year now
and they all seem like they really like my fert schedule.
This is what i doi break it down as follows
First off let me talk about what i use as ferts. I have a 4 part system that i use and most of this is in the brain so please bare with me as i share this one.
I use grow big (hydro formula) Tiger Bloom and then two tea variations. One is high in N for veg and the other is high in Phosphorus when its time to flower.
I apply these through out the grow. I use the to get it started.
then i move to the teas and then back to the and then back to the teas
So i break it down like this:
GB is 3Tbsp/1Gal for heavy feedings. So in my mind this is more than enough for our fave friends. So it states that 2tbsp/1gal is for normal feedings so i use this as my base number. After that i break it down into 1/4
at 7 days i start like this
Day 7 1/4 dose to a gal
Day 14 1/2 dose to a gal + 8oz of N rated tea
Day 21 1tbsp GB and then 1/4 of TB (bringing in the TB)
Day 28 1/2 TB + 8oz of Phosphorus rated tea
Day 35 1.5 tbsp TB to a gal
Day 41 2tbsp of TB and 8oz of Phosphorus rated tea
Then Flush till finish unless it needs something at the end.
I think that this is everything that i do like i said i am not sure as this is all in my head. If the plants demand more that i give more this is just something to go by. I usually do not swap in clean water feedings at all over the fert program. I just use the jug then its gone. Now if i start to see over feeding or lockouts ill flush.
But if i keep my water on point i never usually see a lock out or toxicity.
Hope this helps
