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

Hi all,
First time grow. I need Immediate help ASAP! I fear I'm going to loose my 3 plants and many months of work.
My leaves are drying out, crumbling, withering, weird colors, super thin droopy.

There was doubling of plant size when I switched to flower.

Last week I discovered I had Nutrient Lock-Out... for about a 3 weeks before I knew it.
I didn't know and never monitored PPM, big BIG mistake!!! First testing of runoff was 1500 PPM.
I have completed two deep pH balanced flushes within the past 6 days and now my PPM are 350.
Next watering I think I will need to add nutrients back in (super low amounts) if plants are not dead??

I've never used CAL MAG, base A B or fertilizers.
During Veg they were growing somewhat normal. I topped them initially after 3 nodes developed, then about every 3 weeks. Also weekly LST Low Stress Training was accomplished to begin manifolding SOG.

Propagation Type: from Clones
Strains: Purple Punch, Cosmic Glue, Girl Time
Phase: 12/12 flower
Container size: 3 Gallon plastic pots with drainage holes
Indoor Tent: 3x3x6 with oscillating fan and carbon filter, temp 75-77 degrees
Light: KindLED X40
Grow Medium: no fertilizer potting soil
Water: unfiltered Tap 63 PPM

Thanks to many in this forum, my revised Nutrient mix per 1 gallon water:

1. I start with unfiltered Tap Water, 78 degrees, ppm 63
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 Update grow journal notes for next watering alterations and historical reference.

Thank you @campasino for this Mixing order for nutrients.

Morning Mr. GreenGenes, I ain't much of a plant doctor, but some of that damage looks like you might have had bug problems earlier, I'm not positive though, but even with tap water, you might want to use some cal-mag too.
How often do you water-feed your plants, an do you get runoff every time?
 
D.A.A.S.69 knows MrGreenGenes. Have to agree with him cuz I'm no doctor either. To me they look like they have been overwatered for some time now.
Hey MrGG - one question - have you ever let your pot completely dry out, like when you pick it up it's as light as a feather?
 
D.a.a.s. and Canuck both gave some really good things you should check.
Another one that comes to mind is light, since it looks like more of the damage is on the upper leaves, and leaves bright part of the pictures. Have they grown closer to the light, has it been moved closer or cleaned recently?
Also, what is the fan situation? Could they be getting to much breeze? This can cause similar problems sometimes.
 
Hello, I had gnats in the beginning of veg, but not in about a month. I water every 3 days and add nuets every third watering.
 
I water every 3 days and add nuets every third watering. I have never let it dry out. That seems scary, especially during flower... but Im going to have dead plants if I cant figure this out. Thanks
 
Then that's one reason it looks that way. In future one needs to let the grow medium dry out completely - unless your growing in a dwc.
 
Thanks Canuck147. I see, since starting I've just kept them every three days (with abou 20% run-off each time - which does not sit in the catch tray) and follow others advice regarding checking for wetness in top couple inches. So no, I have not ever let them go beyond 3 days
 
Looks kind of like fungus gnats like D.A.A.S.69 said. But how did you flush for the deficiency was there damage before how do you know it was deficiency? 350ppm is pretty low for flower. Idk about your nutes cannabis needs uses lots of different nutrition. And it's pretty much starving at 350ppm in this stage of growth.
 
Hey MrGreenGenes, yeah ,like @Canuck 147, said, MJ, in soil likes to go from wet to dry, even to wilting a little, it's not gonna hurt a thing, to see a little wilt, then pick up your pot an feel how lite weight it is, then water to runoff, and pick up your pot again, and see how heavy it is, then don't water -feed again until your pot is lite weight again.
I would also increase the bloom nutes like Chefbjy says,
Your plants not gonna die, just let your soil dry out almost bone dry, before watering again, up your bloom nutes, and for sure add cal-mag. Your tap water ain't got enough cal-mag in it.
Good Luck with them.
 
I dont grow soil, never could get the watering down pot myself, not even in my garden, so only DWC here so i may not be of much help. gnatts would be from soil staying too wet yho from what i read in the past, and when i switched to a new LED light factory recommended 24 inchs, which still was too strong for them, i had to back up to about 30 inchs.
 
this is SO helpful and comforting. I will do as you stated. D.A.A.S.69 thank you. I will continue to post progress updates in this feed.
 
How is your drainage? I agree to let them dry out then water and feed normally. I like the weight method for soil. Another thing that will help is yellow sticky cards around the soil and plants. That is a good way to monitor fungus gnats.
 
Great point about height of light. Raising up now. to 36" inches above canopy. The KINDLED X40 is amazing! Very Powerful.

Update for today. All three plants look the same. Not better not worse. I wanted to dry out the medium quicker so I relocated the overhead ceiling fan down to the floor to blow across the top of the pots. Won't know until tomorrow morning if pots feel lighter. I also realized that the day I switched to flower I stopped feeding them base nutrients. My thought was just giving them golden tree and pH correct water would be fine. In normal situations yes. But not knowing I was going into flower in lock out. So the golden tree nutrients just kept building up. And because I was never monitoring ppm ec, explains the lock out, burning leaves and lack of phosphorus. If we learn by our mistakes then I've gotten much smarter. I'm certain my next grow will be setup and ran differently. Thanks all for continued input.

Drainage is fine, into tray. No standing water ever. Gnats are no longer a problem. And I'll start the weight method. Thanks
 
Opening the tent today and seeing a glimpse of hope. Mid-layer leaves looking better as plants continue to dry out. Apparently one of my main issues was the LED light height above the plants canopy. I was 24" above and that was still to close. Now at 36" above canopy. The KindLED X40 is extremely efficient and good at what it does. I didn't start using this light until day 5 of flower, so it was most likely a Big shock to the plants system in addition to all the other issues: pH, PPM, EC, base Nutrients. Moral of story today: Everything matters!
