Plant in trouble

Brianferry · July 21, 2021, 4:59pm

Hi all,

I’m currently day 40 late vegetation. We’re experiencing a bit of a heatwave in the Uk and fear my plants suffering. I’ve got nowhere in the house that’s particularly cool so have been doing my best to reduce the temperature in the unit and the water tank by adding an extra fan and an ice pack to the water tank in the morning and evening. I raised a ticket and was told the temps were 25 Celcius when the lights are off and 30-32 when the lights are on. I’ve added a cap full of liquid oxygen earlier as I fear root rot is setting in but wonder if anyone can suggest anything else I can do? It should be getting much cooler in the next few days but not sure if the plant can be saved.
As always any help and advice would be really appreciated.

Can you get hydro guard?

Can you leave the door open a bit with a fan blowing on the plant? I mean a big fan?

Mpower11 · July 21, 2021, 8:24pm

Also the plant should be able to handle the heat if it’s short term… Like you said root rot will be the biggest problem… Keeping your water below 68 F will aid if possible

Not been able to find any hydroguard in the Uk and not sure of any substitutes. I can leave open with a fan blowing in. Do you think it will help?

Mpower11 · July 21, 2021, 8:33pm

I think it will help you will lose a bit of light but it’s better than the unit over heating… I’m not sure at what temp but at some point grobo will turn the light off to protect the unit

Yeah that’s a good point. I’ve now opened the door slightly with a fan blowing in. What’s the worse that can happy.

Mpower11 · July 21, 2021, 8:42pm

Maybe a little smell in the house besides that nothing that I know of

Sorry to hear this
We just went through a heat dome in my city for a couple weeks but with 5 days of pure carnage heat. So my units even ran i have the wood lids off to let off extra heat.
Unfortunately my plant suffered and the result was ruining a plant a couple weeks in flower. Without moving my unit i have no permanent fix. Can you get a water chiller in the UK?

I have had similar problem here.
When the inside temperature reach 31 Celsius (88F), light goes out until temperature gets lower
Or a temperature slightly over, 31 being the highest I have seen
My plant seem to survive it very well.
I had to open the door and add a fan to blow the air out, just like Mpower11 suggested.
I can confirm it definitely works

Thank you all for the advice. I’ve kept the door open and only closing it when the plants sleeping. Looks a lot better today and hopefully the temperature is going to drop tomorrow. Fingers crossed it will pull through.

Brianferry · July 23, 2021, 5:29pm

So I think the worse of the heatwave is over, now looking at trying to save what’s left. Any advise on best way to get my grow back on track. I’ve been adding ice packs in the reservoir twice a day to reduce the temperature which has been disturbing the roots and I’ve also been adding 2 caps of liquid oxygen. Not sure if that’s the beginning of root rot and if so how the reverse it, or is it time to bin it off and start again?

Todd.grobo · July 23, 2021, 5:58pm

I think she is showing signs of improvement Brian. Kudos to you for trying! She could use a haircut soon, but I think everyone will agree we want to see shes recovering before we stress her out. Maybe take off a few of the bigger fan leaves and let’s see how she recovers over a day or two?

Brianferry · July 23, 2021, 8:26pm

Thanks for the advice. Water change tomorrow, bit of a trim and let’s hope for the best.

FireGuy · July 26, 2021, 7:54pm

Can you post a pic of your bottles? Are they new this grow or leftover from your last? Also a pic of where the stem meets the pod, as close as possible. I don’t think you should terminate yet, just get that info and we can go from there.

Brianferry · July 26, 2021, 7:55pm

Just a bit of an update. I changed the water and gave it a bit of a trim but it hasn’t
grown and a lot of the leaves are starting to change colour. Should I leave it for the week and see if it improves or just call it a day?

Brianferry · July 26, 2021, 8:03pm

Bottle 1 and 2 are from the previous grow, bottle 3 replaced last week, bottle 4 previous and bottle 5 changed 3 weeks ago. The last lines on the bottles are from the last water change.

FireGuy · July 26, 2021, 8:14pm

Stalk looks good, nutrient bottles look normal usage. 1&2 look mostly used…have you noticed a large usage of either recently or calibrated your PH probe lately? Also, no picture necessary but if you pop open the lid and smell the reservoir…does it smell like fresh carrots or kinda gross?

Edit: sorry if these are repeat questions…I didn’t read through the full post

Brianferry · July 26, 2021, 8:23pm

No smell coming from the reservoir, I had a lot of issues with heat in the unit and the water temperature. There’s a picture of the roots in the post.

FireGuy · July 26, 2021, 8:29pm

No smell is good. I saw the pics from 3 days ago but also saw the pics posted today and water temp was 23C+ which is a bit warm, just making sure no root rot. Looks like a calcium deficiency but i’m no pro. Just out of curiosity…do you have cal/mag on hand? If not, no worries.

@Mpower11 @Vicc …does cal/mag deficiency sound/look right?
