Plants not doing so good... possibly insects

[khronik]

sometimes the bug eggs are in the soil,get rid of that siol and transplant into new soil,

Not really an option at this point, and I think that might do more harm than good.

it looks like p.h and heat problems to me are the tips off the leaves crispi.

Yes, the affected leaves are all dry and crispy now. But I did test the pH and it came out as 7.0 exactly. I used the test with powder and a test tube too, not my electronic meter. I did find out that my electronic meter is not that bad, it just only detects acidity, not alkalinity.

There may have been a short period of excessive heat that caused the problems, I guess, although the problem manifested itself during a period where it was actually quite cool in there. Still, it's gotten cooler since then, and the problem seems to have stopped getting worse. My plants were also not ventilated very well, which I didn't think was a problem because they were so small, but that might have been it too. One thing that doesn't make sense though, is that it was the lower leaves that got burned, not the higher ones near the grow tip.

and if you cant get neen oil use garlic crush it up and mix with water and spray the plant it kills all bugs and it dont dammage the plant.

I've heard water with cigarette butts soaked in it works well too.

you mite be sufforcating your roots cos that soil looks a little tight to me.

Oh believe me, it's not. I'll pour a glass of water on the top, and ten seconds later it's running out the bottom. If anything, I think it might be too well-drained. But it does hold moisture, so I'm pretty sure that's not the case.

good luck you need to talk to surreys princess or stinky cos they are the soil queens of canna

Sounds good, maybe they'll answer this.

Oh, here's some pictures, of some plants that were damaged further, and of my setup. I've since removed the mylar on one side for better ventilation. I still want it on the other side though, so it doesn't disturb my flowering plant.

Ok...ph is good but you weren't able to test before you started so..... Did you fert recently?

[khronik]

No, I haven't fertilized at all up until the problem started. After it started I added a very small amount of fertilizer and a very small amount of lime. Probably not enough to do anything.

[khronik]

Oh, I only added lime to a few of the plants, and when I tested the soil sample, it was on the side of the container that I added no lime to.
