Please need help!!!!!

Hey all

Well I'm in trouble again and need your help AGAIN please!

My girls are really sick at first thought that they were just overfeed so started a flush and reduced watering, but this has not helped and it has been two weeks and they aren't getting any better.

We have super skunk going in a 21 bucket recirculating system in 17ltr buckets with the medium being clay balls.

The girls are in an 18 hour light cycle and are only being watered once a day for 15 minutes and have been taken from a mother in the form of clones. The girls are under 3x 400's and temps have been around an average of 24 deg's Celsius, water temp is controlled by a stick heater that is on 20 deg Celsius.

Here are some photo's of the girls.



Any thoughts would be very much appreciated!!!

I know you said you cut back on watering but they still look droopy. Those plants have a pH problem too. check your ppm daily. its important especially when plants are sick like that.

I agree, they look like they're starving.. Where have you been keeping your ph? Noticed you said you thought you overfed, you could be experiencing lock out from a ph fluctuation

Hey Grampa

Sorry should have mentioned before i have been keeping the Ph at 6.0 and have recently added DR Repair which is a Urea, iron based repair feed with 3% Urea Nitrogen and 0.6% Chelated Iron and is said to help with nute problems, i have added this at half the required rate. This has brought the EC up to 2-4.

What growing medium are you using? Is that just rockwool and clay pellets? If so, you should be watering more than once a day. Those pellet only hold water for a few hours and your roots might be drying. What do your roots look like? Can you take a peek?

Also, would recommend a slightly lower pH of 5.8, but a pH of 6 wouldn't cause this. Is your pH meter calibrated, because those plants scream pH issues.

So that's my two cents. Check roots, feed more often, calibrate pH meter, lower pH, and feed modestly.

Bro they are almost dead. You have a major pathogen issue in the res. You need H2O2 (high grade 35%, 50% etc) applied to the res EVERY 4 DAYS to avoid this disaster. The 50% grade is added at 100:1 . Dont hold much hope for these but for next grow.
Also when you flood make 3x5 mins instead of one 15min. Look for cleaning supplies.

why are you using a heater in you res? those things are houses for bad stuff.

I know people use the tank heaters in areas that get very cold during the winter, or are always very cold. Keeps the cold water from freezing and / or shocking the plants. I mostly depends on climate, but they do have their uses in growing bud.

I used one before on a different project, and they aren't too bad as long as you change the water weekly and keep the light out so algae won't grow.

I agree with the heater being added being a problem... you want cooler temps in the res. in the 70's would be great to allow more oxygen in the roots...
more heat can cause root issues, what i like to call the brown mushy root, that is all slimy...
you definitely need H2O2 like *BUDS said...
Plus start clipping those dead and yellows off the plants to try and spring them back...
Feed more times a day especially with clay rocks...
on average maybe 5-9 times depending on how the plant reacts to the feed and don't feed at night, just adding that in there in cause you are...
whats the temps like in there also?
you keeping the light too close?
Get some Cal/Mag to help even some of that out...

Even in hydro never water at EC 2-4. Keep it at EC .8 at the highest during veg. You are killing them with salt. They can't take up water with a media of EC 4. Come on. How did no one catch this.

Hey mm

I'm a tard when i was talking about the EC was reading the CF side of the truncheon so the EC is actually 0.2 -0.4, have reduced the watering length to five minute cycles and more often. Will see how we go

Am living in a real cold area and the temps in my garage can get down to about 5 deg cel so that is the reason for the stick heater and am change the res once a week and cleaning the stick heater as i do this.

The light is about two feet away from the girls.

Watering once a day sounds way too much. I literally have about 2 inches of soil in peat pots and I only water them every 3-4 days. Wait until you can see that the soil is visibly dry before watering again.
