I have been veging these plants for 5 weeks and switched to 12/12 last week and we are now in week 2 of bloom. I had problems with pH in the last 2 weeks of veg and did a flush which emediatly helped and they looked great. But now i’m seeing new problems. What could be the problem?
Your humidity is a little high. In flowering, you want to stay below 50, maybe 55% absolute maximum. Later in flowering, you want even less. The lower the better. The edges curling up is generally due to heat stress, but your temps look good.
Thanks for your comments. I will get a dehumidifyer tomorrow and get the humidity down. No, I dont smoke ciggarettes…
Beeing that I’m using auto-pots, could that be why the humidity is High?
I’ve had the same thing happened in the past to me but my issue was I was running a thousand watt lights that were on an open parabolic hood. Lots of heat to move out. Maybe it has to do with the humidity like @elheffe702 said? Good luck. I’ll be watching to see what the diagnosis is. Maybe it could be just residual effects from the last couple of weeks of pH being off before you flushed them? Maybe the girls will grow their way out of the situation? Hopefully New Growth resume as normal .
I have not encountered it myself and I’m very sloppy but they say if you smoke to nor smoke around them. Plus it transfers easily so they say to wash hands good and change clothes. Like I said I check plants with cig in hand and my grow box is in our smoke room as we don’t smoke in the house but have a room built in my garage
Overwater could be the problem. I let them dry up for 2 days before putting them back in auto-pots. Maybe I should have waited a bit longer. Did anyone see the small holes in the leaves? What could this be?
I just got done fighting my first batch of mites. Check under the leaves using a camera phone so you can see them if they are there. They are close to impossible to see with the naked eye. If they are there they will either be A) under the leaves or B) in the soil close to the stem. The stem make look white.
@FNG101v2 How did you fight your mite problem? I had a small case in early veg and used lady bugs. So far, so good; but I’d love to know how you fought the bastards back.
Happy growing!
