So this is my first grow and I'm mid-late flower with this scrog in a very small tent (80x40x40cm) due to space constraints. Basically the plant is starting to look sick and i want to know if its going to get worse or if i can eventually salvage some bud from this!

I started the plant in Espoma organic potting mix soil under small CFL, all was going fine from seed to veg, few rookie errors but nothing too bad, moved it under the LED and left it to veg for a month then flipped. At the start of 12/12 I had to go away for 10 days and left the plant feeding from a blu mat, it seemed ok when i came back - a bit dry, withered but recovered lots of fan leaves still nice and green and some nice buds had started developing. I then stupidly over-fed with flowertone and this made the soil very acid (PH 4-5) so I flushed and this has helped it recover a bit, but it caused a lot of PH issues.

Over the course of this she's accumulated loads of yellow leaves, dark tips, brown rust spots, and brittle dry leaves - I'm now not sure whats happening and if i need to change anything. Have supplement with Calmag since flushing as have read that LED needs a bit extra and leaves looked rusty/spotty.

However, the dry leaves at the top don't seem to be softening - as you can see lots are breaking up - is this light burn from the LED being too close? I can't move it up unfortunately as its at the very top of the tent!

Its had a pretty rough life and i've learnt loads for the next grow but hoping someone can help me get it over the line?! It should take 10 weeks to flower so I think i need to keep her going for another 3/4 weeks... :-)

Also any idea how much this might yield? Thanks - you guys have helped me out massively to get this far!

  • Strain - CBD Skunk Haze
  • 53 days into flowering
  • Light: Mars Hydro reflector 240w
  • Nutes: Organic espoma (bio tone + flower tone)
  • Supplemented with CalMag
  • PH is now OK (6-7) but soil was previously acidic when overfed with flowertone
  • Temps 68 daytime with light off and 88 night-time with light on
  • RH about 50%
  • Have a 6 inch fan in there but it is shit and blows basically no air
  • DIY exhaust filter which seems to work well - sucks in tent sides, passive intake

Looks like multiple issues but most revolve around excess. Newer growth looks better. Aerate the soil well first. Then I would water again and see what develops. If not worse feed a reduced feed including N.
