PLEASE HELP ME !!
LONG time grower, but newbie to the site. Allow me to thank you in advance for any help !!
Michigan Med card holder since 10-02-09
I've been growing for 20 years, and usually I'm the one others come to for growing advice.
But I'm stumped on this problem !!
I have "blotches" on my leaves
Here's the fine print ..............
-4'x4'x8' grow room. (250 cubic feet)
-2 x 400W MH(to veg) HPS(to flower) in parabolic reflectors with light-spreaders.
-4 plants under each, 8 plants total.
-450CFM blower/carbon filter, running about 280CFM after filter/90' elbow/resistance. (Room is sealed, inlet air is micron-filtered, and I try to exchange the volume of air in room once a minute or two)
-Pro-Mix soilless mix in 5-gal pots.
-GH 3-part Flora series ferts. (I use 10% under recommended/max rate)
-Superthrive & ThriveAliveB1 at mild rate.
-All meters(Light, P.H, TDS, E.C, ect.) and all water filtered with newer 6-stage R.O. system
-PH of water set to 6.7 just before feeding
-Watered every other day, when needed. Top of soil "fluffed" after.
-Containers flushed every 3-4 weeks with water/cleansing agent.
-Assorted fans here and there. Lots of air circulation
-Temps around 78'-80' & Humidity around 50%-60%
-Day 47 from seed today. Turned lights back to 12 hours on day 40.
-White Widow & White Rhino Feminized seeds from the Green House.
-I keep my room/area spotless clean.
-I'm very anal about the details, and have the time.
-I do NOT normally foliar spray.
Hmmm, what else ..... ??
P.S. Some of the leaf tips are curled down from resting against the outside walls ......
I have been using these products/conditions/technics for a long time with great success !!
-The "blotches" have clear "defind/sharp/distinct" borders, not "fuzzy", and are light tanish in color at first, and get darker brown within days
-The blotches started about a week ago, and are all on the bottom 2/3 of the plants.
-The blotches often are in kinda of a strip/line pattern.
-You can see the blotches on the under-side of leaf.
-The blotches are on about 10-20% of the leaves on entire plant (lower 2/3 of the plant).
-The blotches are spreading !!!
-All the plants are affected.
-Lower leaves are starting to yellow/fall off faster then growing new.
Everything else looks good/normal to me.
ANY help with whats going on ??
I can "guess" better than most. (I'd hate to be talked into doing the wrong thing ), no offence.
I can't find any pics anywhere of these blotches ??!!
HELP PLEASE, it's getting worse fast !! I CAN NOT LOSE THIS ENTIRE BATCH !!
Here's some pics ......
