Pest Spray has burnt my leaves

[crabbyback]

I love that clematis. Do you know which species or variety?

The leaf spotting I see on your MJ plant concerns me. IMHO (again I say I don't have outside MJ growing exp.), it does not look like the natural aging of fan leaves.

I suspect a pH/nutrient problem. What is your irrigation water pH? What do you feed? When did you last repot?

[crabbyback]

The tops of those plants look beautiful! Also, your lawn and moss look so green, I'm jealous. Hot and miserably dry here right now.

I'm afraid I'm not sure what species it is (it's my uncles)

I have no idea what my irrigation water PH is. This is my first grow and I'm a real novice. I have been using bio-grow inconsistantly and watering it every other day with a couple of liters of tap water with the bio-grow mixed in. How much water should it be getting at 4 months? I repotted it about 5 days ago, it's in a 40 liter tub at the moment. I have been very inconsistant with watering and nutes though so I think your right. I have also been putting in some superthrive once in a while. Any suggestions for a new consistant routine?

Thanks for all your help man

MJ is pretty picky about her pH. You need to monitor your pH at every watering.

You're going to need a way to test pH (either test strips or a pH meter) and a way to adjust it up or down, if necessary.

All these topics (watering, checking/setting pH, nutrient selection) and much more can be found in the grow FAQs and the stickies at the top of each forum. You're going to have to make a bit of an effort in this too, you know. :jointsmile:

Best of luck, ting. Let me know how you do.

Looking pretty good so far...

The leaves that were affected by the spraying in sunlight will likely not improve, but they shouldn't get worse. New growth will be your indicator.

The spots are caused by one of three things I can think of:
1) Lack of calcium. Molasses in your regimin can correct this.
2) Bug bite neckrosis from individual bug bites making dead-spots.
3) Leaf tip irritation from leaves rubbing or 'tapping' against/on other leaves. Been windy there?

With a consistent feeding schedule you will have much better results.

A word or two about Superthrive.

Hi Rusty

Thanks for your reply. I figured the burnt bits wouldn't repair but the good news is that it has grown nearly an inch since yesterday so I guess it hasn't effected it that badly.

Just been to a shop to get a PH test kit and the guy in the shop told me to just give it water for a week and then start adding minimal amounts of nutrients every 3 days?

Yep, It has been pretty windy. Do you think thats the reason for the leaf tip irritation? They have only just started to curl in the last 3 days. It's been very very hot and I think my bro sprayed some water on the plant during the hottest part of the day which obv didn't help things!

I'll keep you posted over the next few days but apart from the problems I've pointed out it looks fairly healthy right?

1st grow and a little obsessive lol

Thanks

Let the plant hydrate herself. Spraying while heat-stressed, adds stress. Keep the rootball (pot) shaded with cloth or boards or something, but allow for air movement around her. (shade cloth should work)
Don't overwater because it's hot, but make sure she doesn't run the soil completely dry either.

Hmm...that's unusual. :jointsmile:

Go easy with giving nutes every 3 days. Start at a lower dilution rate, (1/2 strength?) and adjust if needed. But form a schedule. Guesswork can and likely will kill your ladies. Always measure your nutes.

[tingting1]

Thanks for the info.

I always measured how much nutes I was giving her, just i didn't have a specific schedule. Every 3 days or so but I now realize that I was feeding her a little too much.

At the moment she is in the house by the window so getting light but not intense sun or wind. I'll let her rest and see how the next few days go and then post some more pics cos I really appriciate the help you guys have given me

[Rusty Trichome]

Overall she looks pretty good to me. A tad too much soil in the pot, though. How long does it take to water her? (are you making sure to add enough water to reach the lower root zones?)

A board leaning against the side of the pot provides shade, keeping roots cooler, too.

Are you moving her indoors every night, or do you usually leave her outside all the time? Unless you are on a rigid schedule, best to leave her outside. Plus, when you bring her indoors, likely you're bringing in spiders and gnats, too. Not good for your houseplants.

[tingting1]

At the moment I'm giving it two liters every couple of days, do you think that's enough or too much?

I take it in every night as soon as the sun goes down and take it back outside first thing in the morning. It seems to have gone well doing it like that so far. I have no other houseplants so bringing pests in isn't really a problem, I would just rather that they wernt there in the first place!
