Symptoms:
1. Older leaves and new growth is lighter in color than preferred.
2. Stems and petioles are turning purple.
3. Newer leaves have a slight tendency to fold up together along the center of the leaf instead of staying open and flat.
4. Internodes are getting closer together... less stem growth.
5. Overall growth is very slow.
Sounds like ???
I don't have pic's yet, but if someone could chime in that would be great.
Thanks!
complete a soil runoff PH test.......
with PH corrected water (6.5-6.8PH ) pour enough water in the pots so the water runs out the bottom of the pot ...collect & test the PH of this runoff water....post both the watering going in the pots and the runoff ph
Well I guess that's the problem.
After pouring 13 gallons of RO water through (PH 6.2) runoff was still coming out at PH 7.5 !!!!!!!!! How much freakin water should be needed get that down below 7 ? The pot is only 3.5 gallons.
Anyway, gave up when runoff was just over 7 and then added more RO water with light nutes which gave final runoff exactly at 7. This will just have to do for now.
Should it be flushed again at next watering to try to get runoff to 6.8 or should it be good now until start flower? (which is at least a month out)
You have to adjust the pH of the flush water to bring your soil runoff down. Flsuh with water @ pH 6.5 in your case.
That's pretty much what was done... flush was around 6.2 - 6.4 and then the final nute solution was exactly 6.5.
Should it be flushed again soon?
You are all set now. Just feed them with a weak complete fert solution, and you can also foliar feed to give them a little head start
complete another soil runoff test when the pot dries out, to be certain you dont have a re-occuring PH issue
Well, I guess I went too heavy on the nutes, now my question is if I need to flush again right away to avoid killing the plants?
basically it's been two days and a few (maybe 10%) leaves are clearly suffering nute burn. Only one leaf has it severely though and all new grow tips are for some reason completely unaffected(?) The few leaves affected are middle to high on the plants.
So can one ride this out? Sound like I'm right on the edge of having to flush again immediately?
I'm growing in soil, how long does it take for the full extent of the burn to show itself? is it over yet?
The pots contain 3.5 gallons of supersoil with 25% perilite. Each pot has two plants in it (never doing that again). Here's what I gave them after flushing:
6ml Flora-Micro
3ml Flora-Gro
3ml Flora-Bloom
5ml CalMag+
5ml Liquid Karma
30ml H2O2
1 drop superthrive
a tiny bit of alfalfa tea
This would give an NPK composition of: 12-6-11 plus 2 parts N from the CalMag/Liquid Karma.
All this in one gallon of RO water. Upped the ph a little with some baking soda to get 6.5. For fun I also tested my TDS it was just under 1000.
This is about half strength so I thought it would be ok but I guess not.... wonder if I can ride it out. Will check on plants tomorrow afternoon. Any help on future nute schedule/concentrations is much appreciated.

Well, in the hope that someone is still checking this thread out I thought I would post an update. Sure would like to get some feedback from someone.
On the third day after flushing the plants were again showing worse and worse signs of nute burn. Not wanting to stand by and watch them die I decided to flush again and then followed with an even lighter nute solution.
Basically what I did was cut the Flora nutes down to half of what I added last time. In other words:
3 ml Flora Micro
1.5 ml Flora Gro
1.5 ml Flora Bloom
I also cut the CalMag+ and Liquid karma in half, so 2.5ml of each of those.
Still added one drop super thrive and a little bit of alfalfa tea and 30ml H2O2.
So a total of 6ml nutes when even a mild dose calls for 15ml based on what the Flora bottles say, and normal for veg is more like 30ml/gallon.
Well, I hope they clear up and that I didn't make any mistakes this time. Would love to get some feedback all you experts out there... or anybody really :)
