What is Happening to my plants - Near Death - Need Help ASAP

Yes I will, checked again just now, still heavy pots. Not watering for at least two more days at this rate. Beings plants locked out, they were not drinking as much. With lockout resolved h20 uptake should be quicker.
 
Yes it does... on some of the leaves. After a week of diagnosing and help from many here in the forum, we've determined it to be LED to close, over-watering with Nutrient lock-out, thus the extreme burning. Thanks for link!
 
Yes 350 is very low, but this is the PPM after two flushes using only pH balanced water. Upon realizing an extreme lack of base nutrients and discovering the Lock-Out with un-monitored 1600 PPM, I had to get it lower. Now that Lock-Out is resolved, my next watering will include very low percentage of nutrients again (Humboldts Secret A,B, Golden Tree, Mammoth P).

Canuck147 still too heavy today, amazing how much moisture remains in the soil. I've already went 2 days longer than when I normally would have watered. Still resisting the urge. Mid and Lower leafs are actually looking better. Now I'm really curious how many more days before these girls dry out... My next grow will most likely be smart pots and coco coir. This should also help with minimizing gnat issues.
 
1600 isn't very high...you lowered ec too fast imo. I've had ec at 4.0 in soil before ppms of 3000s. Campesino has a great guide to managing ec. Maybe he'll chime in here, but I think soil can run a little higher as far as ppm/ec goes...in my experience anyway. Plants will have different reactions to the ec levels and when you raise or drop it too fast it may cause problems. Hopefully you get back on track. I think this is the link https://forum.growweedeasy.com/foru...-ec-ppm-and-fertigation-what-you-need-to-know
 
Chefbjy thanks. I didnt know dropping too fast would impact them, BUT.... They were burning to death from the lock-out. I had to immediately flush to lower. If lock-out was not instantly resolved it would have been inevitable death. They were in real bad shape. My next watering I'll re-introduce 1/4 strength base A B, Golden Tree and Mammoth P microbes. Target goal for PPM around 800-900 / 1.2-1.3 EC. And I will read link to guide and look forward to input from Campesino
 
It's impossible for them to grow properly when the roots are sitting in water, they will suffocate, you gotta let your soil dry out almost completely bone dry before you water again.
Glad she is doing better.
 
gm Mr. genes of green, glad your plants are looking better. when I was in soil the plants would go as long as 9 days before the pots were light. I'm not suggesting you wait that long but don't worry if they take a couple more days to dry. You will know it when they are light so hang in there.
 
Campesino I've read your entire article on EC and its a ton of great info that I need to read multiple times. So Helpful!

While I got you. Can you double check me?

Now that I've discovered (the hard way) over-watering has drastic results. I've also learned Nutrient mixing order is very critical.

This is my updated Nutrient mix for 1 gallon water (individual ml amount adjusted to achieve 900 ppm).

1. I start with unfiltered Tap Water, 78 degrees, ppm 45
2. add and gently stir in Mammoth P, .5ml (Micro nutrients)
3. add and gently stir in Humboldts Secret Golden Tree, .5ml (Micro nutrients - Amino Acids, Carbs, fertilizers)
4. add and gently stir in Humboldts Secret Base Nutrients A, 2ml (Equal parts of B)
5. add and gently stir in Humboldts Secret Base Nutrients B, 2ml (Equal parts of A)
6. Measure this complete inflow mixtures PPM/EC
7. Measure this complete inflow mixture and adjust pH accordingly (need to achieve 6.3 to 6.5 run-off measurement for soil).
8. Slowly and evenly add this inflow mixture into plant containers until 20% run-off of water is in catch tray
9. Measure the run-off: pH and PPM/EC of each container to achieve your soil goals (I'm 3rd week of Flower @ pH=6.3, ppm 900)
10. Update grow journal notes for next watering alterations and historical reference.

Note: Before your next watering, ensure containers are nearly dry. I don't recommended the "stick your finger in it top two inches" method. I almost lost my entire grow with this method.

Thanks again!

thanks! Still drying out (day 5) after deep flush. I never imagined I was over watering but the proof is in the leaves. It may be a couple more days, pots still feel heavy.
 
I think Campesino would agree with me here and say you should measure ec of solution and ph before applying solution. This will give you correct amounts towards your ec goals of your run off ec. If you don't measure ec of solution before watering this will disrupt your target ec outflow. You can always dilute solution to correct ec and then ph your solution.
