I use jacks hydro and always feed the same throughout veg and flower never with any probs for years. The heat was correct about 4 days ago. Was getting above 90 consistently and now staying around 80.
Give them some time. New growth looks ok. Lighten up a bit on the feed, nothing drastic small changes at a time. The older damaged leaves will get worse. Watch new growth or other healthy leaves to make sure the issue is not continuing. It should not spread to new leaves. Give it a week unless you notice this spreading. Upping your humidity can help ease heat stress 60% RH would probably serve you well
Yeah they will be fine.
Heat is not as much of an issue with higher RH. It's the leaf temps that are the key. Higher RH, evaporative cooling, forced cooling like fans, and IR from lights all affect this. Therefore you can have greatly varying air temps with the same leaf temps and vice versa.
RH-radiant heat?
Relative humidity
Okay....still learning all the acronyms lol
Led lighting with decent airflow? Also some genetics do better.
1000w halide running at 50% power. Flowering will be the real test to see how they handle the heat. I’ll eventually run a portable AC but can’t afford it right now
Yeah but you can't compare outdoor changing light intensities, winds, shade etc to indoor steady environment. Like I say IR and all those factors make a huge difference. Take an IR temp gun and check the leaf temps throughout the day they change a lot. Indoors not so much.
Yeah if you can get your humidity up to 60% you would probably benefit.
