LumberjackBudsstarted grow question 6 years ago

So a bunch of my babies are getting this extreme leaf curling. It happened when the lights were off for only like 3 hours. Could it be windburn or Humidity? Nothing is out of whack in the Grow room temps were under 80 and humidity was >70 because I have a dehumidifier. Thanks

Hi @LumberjackBuds! Actually I think it's a combo: overwatering + high humidity + heat. I've experienced similar conditions in the past and also had this kind of leaf-curling. Also, I've seen you got some brand new QuantumBoards, be careful as they often came dimmed at 50%, but you need them dimmed around ~25% to avoid any light-stress for your babies. It seems that over-lighting is really a thing with QBs! So in this scenario I would reduce the light power, put a fan blowing around the pots to dry them quicker, maybe increase the light distance a bit, and see how it goes. Hope this helps, keep us up-to-date and happy growing 👊

Day 20 Flower. Leaves curling Leaves curled over 12 hour light cycle. Ph 6.0. Ppm 950. I have been battling ph drop for a week. Lowered Ppm to 900 from 1100. Seems to have stabilized the ph and now the leaves are doing this. I’m looking to do the day 21 strip of most leaves tomorrow. Should I be concerned?

Help: potential over fertilisation or over waterning I used Biobizz bio grow, 2ml/L and sprayed them more than usual.

Looks like light stress I assume with the canoe and curl. Moved light from 100% to 75% Stil at 35in from canopy. Should that do the trick? Also should I have already had it at 75% and moved it to 100% during flower? Or how do you guys do your light power

What is she telling me?Anyone know what she’s going through? Four weeks old, using tap water with hydroguard and GH FloraTrio nutrients. PH seems to go up from around 5.6 to 6.1 in a matter of hours. Ppm=635 EC=1.2 right now. Been going very easy on nutes, about half strength still. Could that be it?

This is a 27-day auto plant. The problem is that the leaves are crunchy and curled upwards. Soil pH measurement 6.5. There was a fan right in front of it, I changed its direction 1 week ago. Do you think this is a disease?
