Ok I speak in Celsius so my numbers were wrong. Thanks for pointing out. Day 80f, night 55f. So drop of 25f between lights on/off. I assume that's not the issue. I read elsewhere that excessive heat could be the issue so I raised the light and increased airflow. They are doing much better. As a...

Thanks for the reply! In soil. PH is actually spot on. Just re-checked runoff and coming in at 6.4 against suggested max of 6.5 for that strain, so no issues there. EC on runoff is 1.6. Might be time to invest in a temp controller! You can see the cupping and drooping is quite severe. I did post...

Would a 50 degree Fahrenheit swing between lights on/off cause issues? I've had drooping and cupping on my 8 week veg White LSD. I think there's an overwatering issue and im out on PH by .3-.5 but wondering whether the drastic swing in temps could also be causing some stress. All thoughts welcome!

And of course thanks for your advice...

I think you may have just hit the nail on the head. Just re-read the strain review. PH should not exceed 6.5 and I'm at 6.8 sometimes 7.0. That coupled with excessive water is probably the culprit. Note also the review states 800 watts is ideal per m3 and I'm only running 400 HPS. Although I...

Ok thanks! I'll pump the RH up and hold back on any more watering for the time being. Apart from not watering is there anything I can do to speed up the process or is patience the key here?

In soil. Medium always feels dry but I must admit I thought it may be over or under watering (I struggle to tell the difference). I have had others tell me it's everything from under watering to low N. I did wonder whether the high RH meant she was drinking primarily through foliage rather than...

Hey all. Noob here. Need some help if possible! I'm getting severe cupping and drooping in my white LSD. Plant is eight weeks in (veg). Running HPS 16/8 indoor in soil. Temps with lights on at 25c/lights off 18c. RH was at 60% but I've dropped that back to 40% in the last few days (was...
