My first grow has always been so healthy. Suddenly she took a bad turn and I don’t know why or what to do. I’m early/midway (I think) in flower with maybe 3 or 4 weeks to go.
My PH in is 59/60. Just tested PH runoff at 57 (first time testing runoff).
PPM in is 1010. PPM runoff shows 3016 (first time eating PPM in or out). The numbers just don’t seem correct???
I admit, I may have been a little to lazy with my nutes. I also added molasses to my mix and also some bloom fertilizer. Possible I made a couple of lethal batches?
I flushed 2 days with just plain water and now back to my Jacks 321+silica+Epsom salts (based on amounts provided on this sight.
Question - Do you think the flush and restart of Jacks will revive my girl?
It looks like a calcium or potassium. On the verge of lockout by the curling. Your ppms are really high going out. In, they’re good. Ppm’s going in with jacks settles around 1,000-1,000, depending on water source and such. Going out, in coco, they should be relatively the same. Are you watering to full runoff?
@Borderryan22
Until now, I have not collected runoff. My fabric bag was sitting on gravel. I water heavy but have only assumed I was watering to proper runoff.
10am gallon fabric bag and i water 3/4 of gallon each time (guessing the amount).
I now have a tub under my plant so I can see and test runoff.
This is my first grow. I’ve learned a lot. Now I’m trying to learn from an apparent mistake.
I suspect this may have something to do with it. That feels woefully insufficient- I go through 1/2 gal for a 2gal pot regularly.
10 gallons should take 2+ gallons of water to rehydrate properly, probably 3 gallons to get a reasonable amount of runoff. I’m guessing a bit because I’ve never used a pot that large, but based off my 5 and 7 gallon grows, that feels like the right ballpark.
If you flush (give her 10 gallons of plain water, possibly more but I’d start there), then water with full strength Jack’s, then wait for her to dry up and go back to the basics, she should finish out just fine
The damaged stuff won’t recover. You’ll wanna cut it off probably.
Boooom, @Graysin for the reception! It’s important with coco to water/feed pretty liberally. In 10 gallon bacgs, I would imagine it takes over 3 gallons to get the runoff needed. When i grew in coco, in 3 gallon bags, it took 3/4 gallon of jacks to get me a heavy pint of runoff. Coco doesn’t retain moisture the same as soil, so it’s important to soak it well, and fairly often.
I just went back and saw i made an error 1,000-1,100 is a good range for ppm’s of mixed jacks going in, pH’ed between 5.8-6.0. Runoff should not be too much different.
Please just stop feeding the plant. I worked at a hydroponic store for two years and what people don’t realize is nutrients are bullshit. Wait for the plant to tell you that it needs nutrients we’re working with a very hearty plants that evolved to not need a lot of nutrients, stop feeding her. Please stop feeding that plant until it wants or show signs of nutrient deficiency.
Underwatering, or not running until 15-20% runoff, can cause nutriens to buildup in the coco. When a sufficient amount of water or nutrient solution is given, some of this buildup will come out with the runoff. When you water til runoff in coco, without overdrying, you are maintaining that level of PPM.
PPM is Parts Per Million of your water or solution
TDS is Total Dissolved Solvents which is measured in PPM.
