Heat Stress or Nute Burn or deficiency? Help!

Hey guys, please try and help me. I started to get scared for my plant today. I know the lighting in my pics isn't the best.

One of the two tops of the plant has started to look bad. Some of the leaves on the top bud are pointing down, and 2 or 3 of them are burning. I cut the tips of these off and the burnt orange look spread. The rest of the plant seems fine, including the other top. This is just happening on the new leaves on the top bud on one of the tops and started to freak me out

She was about only 1 or 2 cm under a 250w cfl but I thought this was fine because she's been like this most of her life. Tied it up away from the light for the time being. (but like I said the orange still spread even after hours later)

Temps about 80

I've been feeding her 1ml/L of biobizz grow and top max + 2ml/L of biobizz bloom at every feed (as it says in the guide), which is every 2 to 3 days at the moment. Didn't think it was possible to get nute burn with organics at such low doses?

Folier fed her yesterday and maybe didn't let her dry properly before putting her back under the light.
Been folier feeding her about once a week for most of her life. The spray has 1ml/L of Bloom in it

Should I flush her with straight water or just leave her another day? She was fed yesterday so doesn't need it.

Any ideas? Am I over reacting? Pics don't really show properly. Sorry

How is the rest of the plant? Any burning tips? I would back the light off to around 6 inches. 2 cm is too close.

To me the plant looks very healthy apart from that one top. But yes I guess there are one of two ever so slight tiny burnt tips lower down on the plant

I will re-adjust the lights, thank you

Please, anyone else got an opinion on this, or wanna tell me to f*ck off?* I've never dealt with nutrients before. Or heat stress - always grew outside. If it's just that the light was too close should I carry on with the nutes, or do those tips look like something's wrong? *(Please don't tell me to f*ck off)

I personally would only change one thing at a time, or you'll never know if it happens again what it was.

Raise the light as per the recommendation above, and keep everything else the same for a few days.

If the problem gets worse, revisit it and then everyone can try to identify if it is nute burn or nute deficiency.

erm i dont think it would be heat stress from a cfl buddy or heat stress from the temps being at 80 (are running bout 84ish at the min) i can see some nute burn on your pics but only abit..... as spek said raise your light abit leave 2-3 inch above your plant
keep your eye on the sex with that 1 too buddy!!!!!!!

Spek, thank you. Excellent advice.

I would stop foliar feeding. you got buds started and don't want to get bud rot or pm.

Thank you, I was thinking I should stop soon. I won't do it any more.

Hi guys. It looks to be getting worse and it's spread to other parts of the plant.



I'm pretty worried now, can anybody give me advice?

I think the soils dry enough to flush it with straight water now if anyone thinks that's a good idea?

Maybe should add for more info that I'm using All Mix

Also I notice this only started to happen since the temperature went up outside. It's really hot here in London the last few days. But the temp in the cupboard has remained at 80 I think

I really need some guidance on this. Sorry if I'm being annoying or breaking some unwritten etiquette. It's getting a lot worse so I'm going to go ahead and flush it if no one says differently.

I have no idea. But I do know that I have an issue thats like this with my plant. Her name is Fiona (because she just turned ugly for no exact reason). The leaves are horribly yellow with brown dots all over them, very crispy, and the buds are just way to small for 3-4 weeks into flowering. She started out good, until she burned herself on the light. She grew too tall too quick and I couldn't act fast enough to save her. All the other plants (have 4 all together. One sativa, 2 indicas and one that appears to be a mix) are really healthy. I'm wondering whether i should just harvest the ugly one to get rid of the eyesore. Unfortunately i dont have pics right now.

Why would someone "like" my comment sabout my plant being worse and then not say anything (not you, above). Infuriating.. This is my only plant I don't wanna lose it...

sorry it took a min to post, I'm on my tablet

Flushing is a good idea, and I would cool them off some by turning up the fan or air conditioner. They should be ok but it does appear the temp is too high.

Yeah, losing your plants sucks. I had a cloning attempt, but Fiona gave out. The clone failed, probably because I tried a little too late. I just hope that she comes back, but this late in, i don't see any way that is possible. The buds are almost as big as half the size of my thumb. The other buds on the other plants, there is one that is a foot long. That is a huge difference. So I think I lost mine. I can feed over pics later to u if u wanna see. Hopefully someone with a bit more knowledge can help us both

i second that
+ back off the nutes some too

Just noticed more stuff dying lower on the plant. A dying bud. No fucking idea what's going on. Think I'm gonna lose the plant

Thank you. I thought you were being mean. Not feeling good with what's happening to my plant. I have flushed just now. Will put more air con on. Thank you

no prob, glad to help hang in there, plants need to breathe just like us so the more air circulation the better.
