Yep, another newbie. I just hope most of these questions haven't been asked since everyone hates repeating themselves.
So, These babies germinated for a few days, and were planted the day before 4/20. They are about 4.5" (the bigger ones that is) and have some spotting on them. I'm pretty sure the yellow edges are leaf burn from my lights being a tad close, but some of the leaves are spotty also. I don't have pH equip (I owe too much rent to spend anymore on this project) so I can't tell if its nut burn, but I'm really just worried its fungus. Growing in a closet 22"x3.5' (though I can make it taller if need be) and the lights are a few inches away from the tops of the plants. Walls are just aluminum foil covered. I lysol'd the grow area before using,and after the spotting showed up I removed the plants and did it again to be sure.
Ok,Heres my setup:
2x 27w 5500k n:vision CFLs in 8.5" reflectors ,one over each big pot
2x 23w 6000k feit electric CFLs in 8.5" reflectors, one over each small pot
They did however start with 2x15w T8 18" grolux bulbs over the 12 plants I was sprouting
For flowering I have:
2x30w 3000k sylvania CFLs
2x23w 3500k n:vision CFLs
For soil I'm using sta-green all purpose potting mix with time release fertilizer (0.13-0.04-0.09)
As far as nutes go, I only have Miracle-gro all purpose (24-8-16) and schultz plant food plus concentrate (10-15-10). I've added a little miracle grow to one watering, and I water usually every other day, or when the soil is dry a finger length down.
So here are all of my questions (props to anyone who gets them all!)
1. Which lights do you think I should be using for which plants? ideally the bigger pots will be the better ones (the other 2 plants were kinda an after thought)
2. What will yield more, 2 plants with 2 lights on each, or the current setup?
3. Seeing as how I rent and can't put any holes in the wall or door, and need to keep it relatively discreet, any ideas for odor control? My temp is usually at about 86-88 by the base of the plants, so it doesn't seem like I need a lot of temp control...
4. When I can, I put an oscillating fan on them from outside the closet. Is the strength benefit greater than the possibly of blowing bad things on them? (I recently cleaned the whole fan). We are a cig smoking household, but it all takes place in a ventilated room separate from the plants.
5. I want to Co2 enrich the plants, could this be accomplished by simply placing a block of dry ice on the grow floor? Or maybe slightly raised so it pools in the shallow of the pots? Does a regular old yeast+sugar combo raise any bacterial problems?
6. What is the earliest these can start flowering? I'm not looking for a huge yield just a successful grow,low odor and small enough plants to fit my grow area. Is there any way to tell by counting how many nodes/leaves? Height? Plain old age?
7.Would I benefit significantly by reintroducing the straight flouro gro lamp?I only have one left, of the walmart "grow light" variety
8.I have an additional plant in there with no directly overhead light, just kinda seeing what happens. Can it do any harm (other than pollination if male)?
9. Seeing as how my budget wont allow for any more goodies, what would be the best way to fertilize?
10. Am I over thinking all of this?
Of course, most importantly, any advice with whats wrong with them would be most appreciated.
P.S temp shown on thermometer is after fanning for a half hour or so
