Everything was going good until this started happening.

Hydro Growers:
1. Are you growing from seed or clones? Both
2. How old are your plants? as young as 3 months to as old as a 2 years
3. How tall are your plants? anywhere from 28-25 inches
4. What type of hydro system are you using? Coco Drain to waste
5. What brand/type of nutrients are you using? Powdered GH Maxibloom and Maxigrow
6. What is the Ph of your nutrient solution? 5.8-6.0
7. What is the PPM/EC of your tap water? 200ish
8. What is the PPM/EC of your nutrient solution? not sure - I use one TSP nuute per gallon - usually 3 bloom - 2 grow for a 5 gallon bucket
9. What is the temperature of your nutrient solution? 65-70 F
10. Does your PPM/EC show a rise or fall when you do your daily PPM check?
11. Does your pH show a rise or fall when you do your daily check? usually a slow rise
12. Do you foliar feed or spray your plants with anything? no
13. What kind of lights do you use and how many watts combined? (HPS, MH, fluorescent, halogen, incandescent "plant lights") I have flouro and 600 watt HPS
14. How close are your lights to the plants? flouro - very close - 600 about 14-18 inches
15. What size is your grow space in square feet? varies
16. What is the temperature and humidity in your grow space? between 65-80
17. Have you noticed any insect activity in your grow space? some in the coco - gnats...but they are not always there...
18. How much experience do you have growing? some...apparently not enough,...
I am mainly showing pics of the Moms....but the clones are doing the same
I though it was a Mag or Cal problem.....but not sure...

Coco - Drip to waste on the system....more of a spray though.....15 seconds twice a day. The coco stays nice and watered.

You missed question 10. Please provide.

Also what is the runoff EC?
Here is how to test EC using Pour thru method.
How To Do A Pour Thru on Container Nursery Crops
* Irrigate nursery containers to container capacity (10% to 20 % leaching expected).
* Wait 30 minutes to 2 hours for equilibration of nutrients in container solution.
* Place containers to be tested in a shallow saucer to collect leachate.
Pour 1/2 cup (120 milliliters; 4.0 fl.oz.) of water over the surface of a 1 gallon container
Pour 1 1/2 cups (360 milliliters; 12 fl.oz.) over the surface of a 3 gallon container .

1. Pour water over 3 gallon container.
* An alternative for nursery containers is to lift and tip containers to drain leachate into a collection vessel

2. Drain leachate into collection vessel.
* Calibrate the pH and EC test equipment using manufacturers descriptions and appropriate standard solutions.
* Read and record results.

Also should check PH of the medium and report back:
To test the pH levels your plants’ roots are dealing with, take about a 1-ounce sample of moist – not dripping wet — coco out of a container, stir it with 2.5 ounces of distilled water and measure the pH after the mixture has rested for about 20 minutes.


I see signs of overfeeding ph and overwatering. Check the above and we will have a better idea of how to solve.

Trying to locate an EC meter to aswer question 10....the room tays aroun 75-80 when the lights are on.

ppm meter will work as well. if you have not flushed or fed with water at all??? doesnt hurt to so a flush and follow up w a 1/2 strength feed. let em dry out to where there moist between feedings. dont want the coco to be wet all the time.

Temps sound good except if you got a heat spot right there then that can cause the leaves to get burned. Stick your hand in there and see if it feels hot. if there isnt any air movement that can cause it or the light being to close. I use a infrared thermometer to check the leaf temps along with temps all around the room. A hygrometer in one spot only tells the temp in one spot. themometer makes it easy to check it you have little micro climates in your grow. if so, then gotta fix it.

poor through pH - 7.5 - the area under the light is not hot at all - put a temp gauge there and it showed 77 F (right under the lamp while it was on - lamp is roughly 14-17 inches from top of plant - 600 watt). Got the hygrometer and will see what it measures tomorrow.

Have not flushed at all - will do that today and then go with half strength.

Anything else you guys need to help me figure this out?

I have also noticed none of my new clones took - i mean complete failure. - i use an ez clone and made sure to througoughly clean it.

Do you let them dry out between watering/feeding?

are your roots white and fuzzy or brown and rotten?

maybe you have a disease like pythium rot/blight. ...

I'm really curious to know the problem with your plants because mine died the exact same way.. It get's yellow then brown to a crisp.. my medium is soil.. it's a local sativa strain.. It got root bound in my case.. I didn't move it to a larger pot because it was a test run on how low I can grow a plant..

I tried Cal-Mag early on.....I probably over did it as I didnt realize once the damage was done the leafs wouldnt come back. I flushed the hell out of them and am now feeding at half strength for the next few days. I will work up to around 3/4 strength and then adjust based on how they respond.

While I was flushing I noticed a lot of salt build up around the drainage holes.

I got some pelletized dolomite lime and sprinkled about a tsp/tbs in each pot...mixing it in the best I could. Then I poured some more ph'd water on them to settle everything in.

I also pulled all the bad leaves off so I can more acurately see whats going on.

I put a temp/humidity guage in the room and it read 77F and 60% humidity. Waiting to see what kind of averages I get from it. Going to cool it off a littel down to 70-72F.

some could be root bound....over a year old....others are new and wouldn't be root bound yet (3 months old)
I water twice a day on a timer....for 15 seconds - this gives a good watering....the plants arent soaked but definitely do not dry out

thanks for all the advice...I flused as stated previously....lowered the temps and am now at 1/2-3/4 strength nutes. removed all bad leaves and plants seem to be recovering. will update in a bit


Again thanks everyone.
