Here are the pics. I have not added any nutes yet. I do have Tiger Bloom, Big Bloom, and Grow Big. This is only showing on my Auto#1. She is the furthest along with flowers and the fastest grower. The flowers are showing Trichs. The leaves are where the issues are showing.
 
Looks like a calcium problem. Calcium is locked out at 6.4. If your water going in is at 7 and run off at 6.4 then your soil is more like 5.8. Someone correct me if I'm wrong, still pretty noob myself.
 
great way to ask for help... :thumbs: makes it sooooooo easy!

with ph in at 7 and out at 6.4 I'd say you soil ph is a hair low, (prob 6.0 -6.2)
ph vs uptake.gif

looking at the chart, you can see why the leaf ends are showing a bit of def starting...

bring the runoff ph up to 6.3 - 6.5 sounds like it will take a little adjusment. :toke:
 
might not need adjustment if you havent fed yet... but i would gwt it on point first... and then always feed wth properly ph'ed water. (6.3 - 6.5)

heres a rough feed guideline

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 FF 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 FF to get it started.
then i move to the teas and then back to the FF and then back to the teas

So i break it down like this:
FF 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 1tsp 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 tsp TB to a gal
Day 41 2tsp 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
