Possible light burn?

[Ripstick]

Hi, wondered if someone can point me in the right direction?

Buds went from maturing nicely (pistels turning inwards) to starting to shoot new flowers and straight pistels.

Does this look like heat / light burn? or maybe nitrogen deficiency?
I overwatered a couple of times last week, also added a dehumidifier to the room which took RH from 90% to 50%. I accidentally left it on during lights on and temps reached around 30C degrees. I am 7.5 weeks into flower and have another strain in the same tent which is perfect and almost ready for harvest.

Running under 600W HPS around 12 inches from top of cola.
Intake, extraction, oscillating fans etc..

What might have caused this in the last week or so?

Thanks!

Possible n tox or overwatered. I will correct both. It won't hurt.

Light or Heat Burn make Leaves turn Upwards in a Claw like shape. I don't think its looking too bad, if you think its had too much Nute, just Flush, Flush, Flush. If the other strains are looking Good in the Grow Room, it would not usually be the environment. And different strains like different amounts of Nutrients, some GUZZLE, some sip, sip, sip. She may like her's a little more dilute. What system are you using for Grow?

A) Buds went from maturing nicely (pistels turning inwards) to starting to shoot new flowers and straight pistels.


1)I overwatered a couple of times last week,
2) RH from 90% to 50%.
3) temps reached around 30C degrees.
4)I am 7.5 weeks into flower and have another strain in the same tent which is perfect and almost ready for harvest.

cant see pics for now, but
A- sorry this happened, you may recover fine though

1-could have changed ph, locked up nutrient uptake, killed beneficial soil orgs
2-90% Rh is a killer, causing all kinds of issues, likely some mildew hiding in your buds, this affects maturing
3- not crazy hot, but getting there depending on your exchange quality this may be fine periodically
4- some strains take punishment better than others

B- besides the mentioned I believe your affected plant has begun revegging or foxtailing by the way you describe conditions and symptoms. watch for mold, check trichs, harvest when solid cloudy.

Thank you for the replies!

Like I said I have gone back to feeding once every two days just like I had been doing this whole time, so tonight if things are looking similar I will flush with some fresh PH'd water. 5.5-5.8?

I am hand feeding in 25L fabric pots with coco coir.

I have felt inside the tent with lights off when humidity is at 95% and nothing feels damp. To be honest It seems like they grew the best with high humidity. No idea why. I have checked constantly for bud rot etc and all seems fine.

Should I maybe move my lights back down now the temps have cooled off? they're probably at around 18 inches from bud sites now.

Thanks again for the help

Keep Lights where they are, best to be safe than sorry. I like to stick to the Rule of 50cm away, with an oscillating fan blowing cool air between bud site and bulbs. I think the every other day is good for Nutes, but I always look at how she looks. I like to keep mine just on the top edge of Nutrients, to the point were you can just start to see leaves starting to curl under, with nice Dark Green colour, others just follow instructions, everyone has their own ways I suppose. Is it just A&B or do you also add boosters when feeding? When using coco air, how long and how many flushes do you carryout before harvest??

I have a fan blowing across the top and bottom. Last night when i checked the soil was still quite nice and damp so definitely think feeding for three days in a row must have overfed them. Im using the whole cyco platinum range, super stiky, sugar rush, swell etc.. I fed with just ph'd water with kleanse for three days, now a week with just water.. when you say flush do you mean water until run off?

Thanks
