Please help

I grow outside and it was 100 degrees last year and almost 0% humidity. They were the only plants out of 30 that got it.

Im guessing pm is mold? The breeder says they are not prone to mould but my rh is always 45 0/0 so I added two cool misters which now make it 55 0/0 rh but I checked a moment ago and it was 61 0/0 for the first time in three weeks

Yeah PM is powder mildew.

Are they fed all at once or do you use a drip system?

Do they sit in a tray of water or does it all drain away?

Well I do have a drip system set up with flood drippers but the water comes out too slow for 20 litre pots . I like to saturate them and the run off runs away down a tube connected to the tray into a gutter . Completely gone after watering is finished

Good to know. I'll keep an eye on mine when I grow it.

Can this show up as little white ish circles or is that the drops I have split off nutes ??

Do you let them dry out a little? Have they ever wilted from not getting enough water?

If your water is hard you can get water spots. If you look at the spots using a magnifying glass or a good camera you can see the fuzzy nature of PM.

Never wilted I flood them once a day but I have left a day out today so hopefully the roots go looking for water and grow more , the hydro balls make it dry out a lot faster as it's 60 o/0 coco 40.0/0 hydro balls so I just have to make sure it doesn't go desert kind of dry

My water ppm is 40ppm tap water and ph 7.5 I will do that

Adding co2 tommorow but with a simple controller which you just type room size in and it act's accordingly. Worried

I always push them until they show wilt so I know what they can handle. Canna prefers dry to wet.

CO2 works. I saw a study where they increased growth up to 3X!

You can check the PPM/EC of your run off too and that can help tell you if you need to feed more.

It is so hard with coco though you have to do the sample test with the medium

What size footprint are you covering with your lights? And what's the room temperature?

Click to expand...

The room temp atm with ac on is 25oc and the 3xhps cover 1m2 each so that's 3m2 plus I have a 400 and 600 led in there . My room size is 11ft x11ft

That's a shame . Is that because humidity is high?

yes.first time growing this strain as well.it can be treated.all is not lost.thems the breaks growing outdoors

No, you should be watering until you get 10% runoff out of the pot/container. So if you water with for example 10 liters you would want 1 liter to drain from the pot/container. Measure the water that drains out.

I do 30 o/o runoff but to test the runoff ph is hard and the ec is always crazy. But if the ec is higher in the runoff than when it went it is it because they are eating well or not ? I do not get how to judge runoff results
