Wind burn? Drying leaves!

[SourDiesel42050]

Hello my 420 fam,
I was wondering if guys turn off your fans while the lights are off? I found my leaves were getting wind burn in veg stage, and in bloom stage my top top single leaves were drying out towards the end of the grow. How do I control my humidity and tempeture with 2x 600w HPS lights in a 2.4x 1.2x 2.0m tent? I have a massive carbon filter and fan, which is giving me negative pressure. What's the recommended temp and humidity? Cheers

At your stage of flower crisp leaves are common. Keep them fans going. Better to have some crisp leaves then bud rot. Looks good.
As far as recommended temp & humidity for late flower... 74 degrees lights on, and between 30-40 % humidity is what I shoot for.

Sweet cheers for that mate, was my first grow so still learning all the steps to it haha.

No sweat. I edited my reply to answer the rest of your question if you missed that.
If your up over 55% humidity late flower you can run the risk of bud rot without enough air flow.

Oh sweet yeah I think it was getting down to 35% at the last 2-3weeks of flowering. Is that what normally happens it drops as they get later in the weeks?

Well that depends. It did that for me but that was due to the season changing and going from summer to fall. Summer is high humidity. I don't think the plants change the environment such as humidity. It's controlled by you.

Yeah that will explain alot cause we went from winter to autumn so that probably why. Cheers for that info I love learning and asking questions. It's been a great success this first grow can't wait for the next batch of white widow

Looks good to me just keep watering and dont let the soil dry out, your leaves wont dry out either. I keep fans on 24/7.

I'm in hydro DWC cheers she's all pulled now in the drying stage. Is there a certain temp and humidity you need for drying as Well? I just leave my exhaust fan and the carbon fan going seems to be doing well.

Congrats on your harvest. I just hang plants until they are mostly dry to touch. Not snappy just mostly dry. Then trim and into jars then more drying if needed.

The only time I worry about rH is in summer when its more humid. As long as the humidity in your room is less that say 60-65% rH you the plants will dry perfect. Not the best if its REAL dry or real humid.
