ph isn't going to do that, and even a p toxicity in the extremes aren't going to burn like that. leaves don't go dry and crispy from a deficiency. that right there is from lack of water. leave any flowering plant past wilt in soil, and that is the result, right there in the pictures.

water more often and that won't happen. try using drain pans to allow some wicking. the leaves are dead and dry as the result of "lack of rain"

fungus gnats?

yes, you treat one plant, collect male flowers, dry them, burst them, then pollinate new plants. as for the cost of fem seeds vs regular.... you have to create pollen to make fem seeds. to make seeds, you just need a male. normal seeds are easier to make, and therefore cheaper.

no. with dwc, the 5g res acts like the ground, the roots don't comprehend the size of the bucket; there's no such thing as rootbound in dwc, the buckets will be full of roots come harvest (imagine a solid form of roots in the perfect shape of a 5g bucket...). 5g per plant for dwc, it makes the...

14 day res changes came about to save money on nutrients. at 14 days the concentration of nutrients (even after being topped off with fresh water) is still in the "normal" range. much longer than 14 days and the salts begin to fallout. and any plant will pull differing amounts of nutrients...

many places. it's very expensive. you can probably find it on ebay. plug it into google and see what you come up with.

that's what i'm talking about. mature plants will begin to flower in the first night cycle. these plants will have preflowers. plants with no preflowers are not mature, and will need to mature before they begin to flower. this is accelerated by lighting cycle, but they still veg in the flower...

resin is genetic, and the result of your ability to provide proper conditions. correctly grown happy pot plants will produce the most copious amounts of resin. cold will have no effect on the chemicals within the trichomes. cold temps slow production a bit. ideal temperatures are 75-85 for...

colloidal silver.

almost every strain in existence is a hybrid. true land race plants are impossible to find unless you're in the know. indica dominants do much better with acclimation to cold temperatures, and some are very cold hard and frost resistant. acclimation is the key, and on nights where it may drop...

frost will affect the leaves but not the buds. if the stems freeze, the plant dies. it usually has to drop below 30 at night to kill a plant, so quick snap frosts are not a big deal so long as it takes a while to get that cold, and warms up quickly.

small light leaks are almost never a problem. i have a box that the door is left open 2-3'' 24 hours a day. it does get light in the darkness, but not enough to inhibit flowering. the plants i run are proven hardy and don't reverse, and i have no issues with hermies. most will tell you absolute...

i run 5kw and there's no worrying about power. pay the bill and you'll never have a problem.

this is not really true. most plants, especially indicas will keep healthy green leaves until harvest if fed properly. it looks like an overdose of phosphorous combined with high temperatures (those bubble looking leaves are stress leaves). you've plenty of nitrogen (look at the color) so your...

even seeds started on 12/12 will veg for a few or several weeks before they begin to flower. you wouldn't count your flowering period until the plants actually start to flower. ie, if you had a 8 week strain and you force flower before the plants are mature, the time that it takes for the plants...

i understand. if you're 6 weeks in the plant will probably continue to flower if put outside. try and find a partially shaded area to place it for the last few weeks, so you get mature dank buds, and weight to go with it. pistils really don't get you high, you need those calyxes to grow big and...

it's almost always not worth it. let it go a few more weeks if possible.

in summer? lol. no, no issues. think of how much you use to water a lawn with a sprinkler system...

and yes, adding nutes to nutes as the water level decreases is raising ppms. the plants use much more water in flower than nutes, and you should only top off with plain water between changes. i change out nutes every 14 days.
