3rd Degree burns

Hey guys,

My first grow with HPS bulbs. I totally underestimated the amount of space necessary between lights and plants. But my grow room pretty small and now I have to see it through before I can increase the ceiling height. Some of the leaf surface temps I was recording were around 96 degrees or higher. I managed to install an aircon now and am pumping cool air around 60 degrees onto them. The LST Is now between 68 and 78 degrees.

So my girls got quite serious burn. I am 3 weeks into flower and quite a few of the buds closest to the light got badly burnt, to the point that all the leaves on and around the buds are curled/clawed. Some of the buds are completely dried and clearly dead. There are still quite a lot of buds that were further away from the lights and they are looks beautiful.

I am working with a DWC hydro system and for the moment I've dialed back on the nutrients slot while they hopefully recover.

So my questions are:

Does anyone have experience with this kind of server burn ? Can the buds recover after such heavy burn given that the environment is more stable again ? Was I right to dial back on the nutes ?

Also, with the aircon installed the humidity is very low, not exactly sure how low but where I live its bone dry so even before the aircon, humidity was very low. Will this be an obstacle to recovery? Not sure how the hell I could increase humidity sufficiently in my cycten where air is passing through the entire system so quickly.

And feedback would be greatly appreciated

Welcome to RIU. People are poking fun at you but don't sweat it, it is because you are asking blind folks to describe the sunset. It is meant to be light hearted. Do yourself a favor and post some pics of your plants/setup so people can see the damage and provide proper advice.

Honestly, there were so many questions I asked that could have been answered without a pic. Like, was it right to dial back on nutrients after the plants have been injured... Or will low humidity be a big issue. Or how to address the issue of humidity in a system where air is circulating so fast.

I dont see why you would need a pic for that. My girls were sleeping and was just looking for some feedback in the moment.

Dont see how I'm being a troll... I posted as a concerned grower and got some pathetic joke of an answer and more action on my thread after calling a twat a twat.

The simple answer is that without seeing the damage done it is hard to answer your questions.
Was it right to dial back to nutes, depends on how much damage was done which pic would show. Without it the answer becomes maybe.

Will low humidity be a big issue, yes it will for injured or healthy plant. Get a humidifier. Cant tell you what size with description of grow room is small, again a pic would help give a proper answer.

How to address issue of humidity where air is circulating so fast. Again a pic of setup would be helpful. Many deal with humidity, perhaps the answer is to circulate less air, it depends on your setup which nobody can see.

A well known member made a joke and you responded with a horrible venom filled response. It was meant to be light hearted, it's not like he said post pictures you twat or we cannot help you. Now I am trying to help you but you don't have to listen to me, a man's gotta do what he feels is best. Good luck with your grow. :peace:

This is where pics would really help. 3 weeks from flip plants don't usually have "buds" exactly. They would be mostly pistils and haven't started swelling yet. So are the pistils burnt? Or sugar leaves? Or fan leaves? Are they more than 3 weeks from flip?

Without seeing any pictures i would probably recommend cutting off any tops that are severely burnt and letting the buds below keep going.

Low humidity is generally not a problem for cannabis especially in flowering.

People on here don't like attitude, you're asking for help and someone asked for a picture and your reply isn't exactly polite lol.

Anyway, without a picture of the room, plant etc I'd ask, can you scrog? Do you have the space? As in instead of plants going up, net them so they go out and open a canopy

That's the thing, he didnt "ask for a picture". Rather made a sarcastic remark. Personally that feels more like "attitude" to me. Anyway, don't really care, just thought it was a stupid remark and after a long day of work and being concerned about my girls, I think everyone can agree that sometimes it's hard to keep a sense of humor.

Anyway, will take a pic for you twats after work... (that was humor btw)

So here some of the long awaited pics.

Please bare in mind it's my first HPS grow and also in the country that I live in it's near impossible to get some of the things that may seem so basic to growers in other countries. Like ventilated hoods for example, they need to be imported privately and nutes are not tailor made for cannabis growers... bla bla bla. You get the picture.

The grow space is ONLY 3.9 foot high !!! Its a fuck up... I realise that yes. But I have to see this through now before I can increase size dramatically and move to a more suitable location.

Everything was going beautifully here until season started changing. There was a cold front and when that abruptly ended, temps went up dramatically and within two days the girls were scorched. As I said, I have installed a aircon and directed cold air over the bulbs/worst affected areas. The temp is stable now with grow room temps around 75 and 78 degrees. Leaf surface temps right under the bulbs are 84 MAX. Bulbs are at at night of course from 6 PM to 6 am. In the earlier hours of the morning the temps are going much lower. When I check on them in the morning the room temp is around 57/60 degrees. Difficult to keep in in the sweet spot all the time... but rather cold that hot I suppose.

Some of the bud sites in the pics are still doing very well. Some have been damage for sure with many if not all of the sugar leaves being curled and dead but if you squeeze the site gently it still feels like there is moisture and life hanging in there. Some bud sites are completely dead. They are brown and crunchy. Fuck up. Maybe positive is that there are far more sites that are damaged but hanging in, than there are dead and dry... whether they will recover or not is another story that I was hoping to get some INTELLIGENT feedback on.

When they were busy cooking, there was a fan at the entrance of the room blowing air over the illuminated areas toward the back of the room. I think a lot of ambient heat built up at the back. I noticed now that although the bud sites still seem to be alive, most of the pistils on plants at the back of the room seem to have turned brown, while the sites closer to the entrance seem to all still be white... any info regarding this ? Due to the stress obviously but how negative is it ?

As I said, I'm really just making due with limited supply and space here and i need to try see this through with the best possible return. I would really appreciate any constructive criticism.

There is a certain protocol we follow. No one really gives advise without seeing what they are advising about.

Its sound. Post pics bud.
