This has been progressively worsening over the past week and a bit. Soil PH was 6.9, and now has been reduced to 6.3. Plants were thoroughly flushed with plain PH water, and were fed last night. Only a few plants have this, and it's only a couple fan leaves per plant approx. 3/4 way up the plant...
What is it?? Nute burn?? They were fed last night 1300PPM, GH 3 part. 2 nights ago I foliared with Sensical.

Imo, if you are still having the problem, it doesn't look to be anything nutrition related. My first thought was pests. Then you mentioned the possibility of fungus and no pests. So my last thought was some sort of disease or fungal attack. Your humidity is at 50% so I doubt a fungal problem, my final idea is a disease of some sort. Don't quote me, but maybe a leaf septoria. I keep thinking that that looks just like a pest attack, but if your positive that's not the case, then a disease would be my final guess. Sorry I can't be of more help, but if it is disease, try to cut of the badly affected parts and vectors of the problems, use neem oil, and finally try a fungicide and see if things improve. I'm a bit skeptical because disease like this rarely occur indoors, but rather outdoors. Exposure to outdoors or anything that could have caused a tranfer of foreign debree can however cause indoor diseases that are rare. LMK if this helps or if things get worse or don't change. I'm only a novice when it comes to things like this, but I will do the best to help if I can. NWHello everyone
Situation:
- 5 fem SuperSkunks (seeds) in Soil BioBiozz All mix
- Germinated about 2 weeks ago in peat pallets
- Transfered to soil 4 days ago (problem started)
- No nutes given yet
- Humidity around 50 %
- Temp between 17ºC and 24ºC
- PH 6.2
- Excellent air ventilation: Exhaust is a 400cm running 45 min every hour(please tell me if it's too much or not, and constant fan blowing directly into plants.
- Using 2 FL 18 watts tubes 24/0
- Plants are 10 cm from bulbs
-Using Tap water
- Plants don't have pests
- Watered 4 days ago when transplanted.
Problem: Leaves seem to have 2 types of problems: 2 kinds of spots, 1 are reddish brown and others are dark and seem to have also yellow on them. Seems some sort of fungus
Pics now:
Hey, well as this is a stress test, it could be a result of your experimenting. Lower temps inhibit P and cause changes in color and slowed growth or maturation. Roots can suffer due to cold temps, and sugars produced by tissues that have slowed growth could actually decrease the trich production. The leaf you are concerned about isn't any indication of a problem within itself, just a result of other influencing factors or the strains genetics, but I have never seen that kind of growth from genetic expression. It probably is just a reaction that is natural due to the cold. IMHO if you want more trich production, stress is the worng way to go about it as the plant will spend its energy on surviving from the stress and the resulting yield will also suffer. A suggestion on more trichs is to give your plants what they need and keep them healthy. Then experiment with different nute supplements and most of all, light spectrum. Light spectrum IMO is the key from what I have seen and experienced. Not only do I believe the trich production would increase, the overall yield would increase as well and allow your girls to find their true genetic potential.Okay people... Here is my lil issue.
Seeds germinated and planted 10/8/2010 in soil, hand watered.
I transplanted and started 12/12 on 10/28/10.
They are a hybrid between an auto-flowering Ruderalis/Chronic (it's skunk x, northern lights, and ak47 crossed w/Ruderalis).
Lighting is a 1000w MH and 1 400w HPS.
Temps run 50-60 at night when the lights are off and right around 70 w/ lights on. (I am deliberately allowing temps to drop at night. I read that it could increase trichs, so I am testing the theory).
Okay I think that covers the set, so onto my issue.
On several plants I noticed that the leaves are collapsing instead of fanning.
Does anybody know what causes this? Is it something that I need to be concerned about?
