Hi all,
Really could do with some help !
I've been trawling forums for ages now and I'm at a loss as to whats going on.
My girls are starting to curl upwards have brown edges and some brown patches on the leaves, Magnesium I see mentioned as the problem, heat stress, loads of other suggestions so heres my grow details and pics.
Nutrients - Hesi Grow, Supervit, Root Complex & Enzyme @ 20% Strength
Veg Stage 6 weeks
Shiva Haze and Jackberry
400w HPS - 60cm above the tops with reflector
Temps between 22C & 29C
Hum between 50% - 70%
Extractor Fan & Oscillating Fan running 30 minutes every 2 hours alternatively (control heat and air flow)
Soil less Mapito Mix (Reused previous no problems)
PH of Tap Water 8.2 PH Down when feeding or Flushing to 5.8/6.2
PPM of Tap Water 85/95 PPM with nutrients 140/150 PPM
3 Gallon Pots
Feeding once per week always with nutrients (using the weight method or finger in to knuckle to determine feeding once a week based on that)
Last week I flushed them with 6.2 PH water as they were showing what I though was some nitrogen issues and a couple of odd bits like turning leaves and I hadn't flushed them since the start, the flush was done 5 days ago now and these symptoms started today rapidly.
Any suggestions as I dont know what to do with them and they are starting to get to the dry end of the feeding when they need to be watered or fed again !!
