you can add to tablespoons of unsulfered molasses per every gallon of water you give them to treat cal/mag deficiency. I do this from early vegetative state all the way until harvest. I even flush with it. Molasses also thickens cell walls, increases resin output and creates a very distinctive...
most of the minor necessities are readily available, as 99 percent of the equipment is legal and not really intended for growing pot specifically. Neem oil and other insecticidal soaps are general purpose gardening equipment. nursery's almost everywhere will sell ladybugs. Nobody asks too many...
no home depot? my mother uses a diluted dish soap mix to keep bugs off of her flowers and shit, but I would research that before attempting, might leave a residue that would block stipuoles
canoeing is when your leaves start to resemble upside down canoes, this is generally caused my overfeeding. Always remember spots and shit happen a lot and they are not always fatal, but patience is key. There is nothing you can do to rid a leaf of its spots, just prevent them from spreading to...
I would try just getting another cutting online. There are some reputable places to get salvia cuttings. Sorry though I don't know dick about cacti. (I am a mushie lover) But I do know of the history of salvia, and have tried it enough times to know I will never smoke it again. Nothing sacred...
As far as I have ever seen, every lamp has to have its own ballast, larger commercial grows or just warehouses, parking lots and department stores tend to utilize lighting with a built on ballast or have a custom wiring job done wherein they have all the external ballasts wired to a single...
Sudden curling and lower leaf decay is a definite sign something is drastically wrong in your soil, can you provide some details about your watering/feeding schedule?
You might try holding off on the nutrients a tad, looks like you got some canoeing going on. If it gets any worse a flush may become necessary. In the meantime look for new spots forming in your newer growth to gauge if it is getting worse or better. I also recommend removing any leaves that...
T.H.C exists on the plant for two purposes, it's useful as a U.V. buffer to protect the plant's sensitive reproductive organs. (Offering an increased amount of uva and uvb 6 hours into your light cycle for thirty minutes every day during flowering can greatly increase trichome production) In...
You could top now, or a couple weeks before switching your light cycle. If you have a magnifying glass keep an eye out at the middle internodes for preflowers. << They look like this if they are female.
Leaving them in the dark for a 24 hour period before harvest may increase the potency a bit, plants will react to small amounts of stress by increasing trichome production. Too much stress may cause false seed pods to appear.
All those bulbs for just three plants? You'll do fine enough. A mixed spectrum is always best too, make sure you have a 6500k dominant spectrum for veg and 2700k dominant for flower. Keep your plants low as well.
might try applying co2 during your night cycle, that way you could turn off your ventilation, and just have one fan on, low.
other than that more fans would be an option. never hurts to have more fans.
