Just finished this grow and wanted to share. I germ'd all 3 seeds and all 3 it felt like were in competition with each other for my affections lol. They grew strong and healthy the whole way with strong branches and dense colas. They were the monsters of the room. Only have pictures of two due...
Your grow room must be huge! Good luck with that as I am going to germinate some of the Heavy Duty Fruity soon and possibly a Dark Star (from the freebies). Female patients I have found out, on average, like the "fruity" strains (even if it's just the name).
I would try that full moon as the pics look great, but... I just ordered a bunch of seeds from the attitude promo. Lots of freebies to try etc
But.... Next grow I will be growing 1-3 Nirvana PPP as I have read and seen a lot of good things on it.
Just found this great thread and have a few nirvana strain pics to share.
Strain: Jock Horror
Lights: 2x 600w (MH veg/HPS flower)
Veg Time: 4 Weeks
Flowering Time: 8-9 Weeks
Soil: Miracle Grow - Moisture Control
Nutes: Fox Farm (Big Grow, Tiger Bloom, Big Bloom)
Final Yield: 2 ounces average...
Meant to say molasses "as an alternative" might help too. It contains calcium, magnesium, potassium, iron and carbs for your plant (and sulfur if you get molasses w/).
Black Strap Molasses is good. 1-2tbls per gallon.
Like Serapis said, it's prolly your ph.
I think also you should stop foliage feeding from here out on the affected plants. Just add nutes through the soil from here out after you ph your soil.
A little water and time and should be fine.
When you manually apply the CO2, bursting from the cannister, do you ever point that burst directly at affected plants?
Do you foliage feed at all?
Temperature seems fine if it doesn't dip below that when the lights are off longer.
How high are the lights from the affected plants?
Is there a fan near the affected plants?
What is your room's relative humidity?
Is the CO2 near affected plants?
What is the room temp at night (lights off)? I live up north so without a heater my grow room can get down to 60 on cold nights.
Look good.
What chuck is trying to say is that water drops on plants w/ lights on (close and/or hot) can make the drops become light prisms which can in turn burn your plant on said areas. If you want to "mist" your plants, do it when the lights are off or just coming on.
Everything looks good once you get the 400w.
Haven't used Flora series nutrients. I use foxfarm Ocean Forest w/ Big Grow/Tiger Bloom/Big Bloom along with some Superthrive for root development etc. Works great for me.
From the info/pics provided it looks like they are having some severe deficiencies.
Distilled and RO water lacks Calcium, Mag. Need to substitute those 2 yourself. That's what the brown rust spots that start small an spread throughout the whole leaf are caused by. Starts on lower leaves an...
They all look decent enough, some healthier then others.
I'd say if your soil has good aeration and your pots of good drainage, give them some more water if you feel they could use a little more.
Also a ph meter for your soil would help. The vanilla kush pics look like the ph is high.
