Please help me

I found my tent like crap today.

Cut off every damaged leafs and gave the plants a flush. Dont know why the damages occured. Gave them there first shot of nutes a couple of days ago. Is it a burn bacause of the nutes?
I use canna terra vega. Used half the recommenden ammount.


Growing in soil, ~25days old, 5 gallon pots.

According to their VEG schedule:

http://www.grotec.co.uk/assets/helppdfs/Canna Terra Grow Guide.pdf

Their full dose is only 0.6 EC and you stated that you only fed half the amount. There's no way 0.3 EC could have done that to your plants. If you didn't make any mistake with the nutrients, then your pH of your soil may be out of line or you have some other sort of problem.

Agreed i think there may have been a miscalcuation.

I bought a new ph meter and it showed that the water I am using for watering have a PH of 8,8 when nutes and 1 ml of PH up is added. But the soil is buffering the ph to 4,9 when I measure the water coming out the bottom. How is that possible? SHould I add more ph up?

Quick answer, please

Update: Watered with another gallon of 10.4 ph and the water that came out was 5.8. What should I do?

 

[trichrider]

flush.
do not let the medium dictate your ph.

ph water to 6.8 going in, after adding nutes. if there is something in your soil causing 10.8 ph to drop to 5.8 then maybe change your medium...

nuetral to 5.8 is understandable...a drop of 5 points not so much.

 

[DHopeland]

Damn it!
I'll just wait a couple of days until the soil is dry and then I plant in new fresh soil. I've never had any problems like these before, and I honestly havent measured the PH level more than a couple of time before. It just have to be the soil.

 

[MynameStitch]

need more info.... what conditions are you growing in? What soil/soiless are you using? pH before and after nutes were added? ph of run off that kind of thing...... Where did those leaves come from on the plant? depending on what kind of soil you have that in.... if it's fresh soil and use half dosage it can and will cause burned leaves like this.... not saying thats the case but ive seen it plenty of times...... I don't have enough info on his grow to give a definitive answer yet.....

flushed yeterday, waiting for respons...

 

[SkinnySRHKID]

one of my plants looked the same on a few of its leaves, I am also looking for the problem becuz i using foxfarm soil with no added stuff. I am going with it might be the ph of the water!

 

[RubeGoldberg]

Update: Watered with another gallon of 10.4 ph and the water that came out was 5.8. What should I do?

Going in with a higher pH isn't going to fix the problem any quicker.

keep flushing your medium at 6.3 give or take until the pH of the runoff rises to above at least 6.0, then you can start feeding again.


you're locked out, you likely have a nutrient buildup.

Nutrient build-up from 0.3 EC? unlikely.


And to the OP... don't wait a couple days till it dries out and then transplant.. waiting will only make matters worse, not better... Keep flushing with 6.5 until the runoff is above 6 and it should start to improve, if you just leave it where its at and wait for it to dry so you can transplant, it will probably be dead by then.

 

[MynameStitch]

Since he already flushed how are the plants doing?

 

[hush]

I've seen some heat-dmaged plants look similar to that. Your temps okay?
