Change your water is one way, if this happens a lot indicative of old water OR temps changing a lot in your rez. When the water heats and cools your PH will go screwy. You sure your water doesn't have chlorine in it?

you ALWAYS mix nutes first, then adjust ppm accordingly. This will ensure a proper balance of nutes. Now when I adjust ph personally my PH adjusters don't raise ppm enough for my EC tester to measure it. It would only make sense that it does, I've just never noticed enough of a ppm difference to...

keep them, that's quite normal in fact. If the condition persists which it should not then I'd toss em. As previous poster stated, almost a natural mutation. In some instances that will happen but instead a split will happen causing two branches to form. Unless you're hurting for space or light...

you should change the water "as needed" or when you notice the ph levels fluctuating alot. at least rinse down the roots as they will accumulate "goo" and nute residues. To my experience superthrive will create goo and/pr residues in your rez. After just one use i notice a buildup on bottom of...

Try lowering ph to 5.5. variable is 5.5-6.0. 400 ppm on a 3 week baby seems a bit much. I don't stress ppm a lot but I only go as high as 700 through out the veg. I also use dirt "Mention because our values will differ". I run up to 1000 during bloom. A good reference for ppm with your NPK...

It's a weed, it can take a few shots before you finally kill it off. Kind of like a cat with 9 lives. As previous poster stated, treat it and it will rebound. Typically during transplanting you'll notice drooping. I would'nt worry at all, what I would do is make sure to NOT over water it right...

Hey all, I'm having some issues with my clones I don't quite understand. It appears after a few days of them sitting they will "bruise" at their base "just above the RW" and wilt over as if to die. I understand wilting is normal, though the bruising makes it seem a bit more then simple wilting...

yes but keep the lights 3-4 foot away from the tops for about 3-4 weeks or until you notice the plant is strong enough to take in more light. when theyre that young too much light is a bad thing as well is heat.

if you constantly feed and only give plain water "every now and then" youll end up with a salt buildup in your soil. generally youd wanna feed once or twice and then give plain water once or twice. "flush" your soils as often as you "feed" your soils. if need be pickup a water meter. watering...

could be preflowering which would show sex. even at 18/6 lighting. your pic is a bit to blurry to tell if thats leaf cluster or seeds.

days if not a week or so it should be done, typically people use a 75% colored hair ratio. once the white hairs, 75% of them turned brown, youre done. the other way would be to use a magnifying glass and look at the trichomes (crystals on the plant) using this method you can get an exact due...

once you "turn" your plants into flowering stage "12/12 lighting" you do not want to bring them back. thats known as re-vegging. 12/12 lighting cycle will produce a hormone telling the plant its time to fruit/flower. once turned leave them 12/12 for about 60 days or until you know how to...

lol at growing a peach on a flow table. yes peaches grow on trees, and yes you can grow anything in hydroponics's. if you consider where we got the intelligence to grow hydro - mayans were doing this back when they were alive, i seriously doubt they were growing cannibus. I'm gonna think they...

1 gal per foot you plan to grow is a generalized pot size to use. If youre gonna grow them to the cieling, 8 gal pots ;P

" Should I have kept it up (flooding) till run off was in the range I was after?" YES! your run off water is the ph value of the soil. when you flush you're trying to neutralize your soil. I.E. put it back to PH 7. 7 being the neutral. lastly I wanted to mention as i missed the quote before...

cool tubes will drop you down temps quite a bit. personal experience, 600 watt hps in a 4x4 closet. 95*f temps. introduced a air cooled hood temps dropped to mid 80's. AC and/or heater will be rated by btu. btu is calculated per your cubic feet of the room. google for a btu calculation. as...

when in doubt - flush them out.. soil ph 6.5-7.0 range for soil, hydro would be 5.5-6.0 some would say 5.5-6.5. id definitely flush their ph back to a neutral range then water w/ proper ph'd water. anytime you start to have any discoloring youre not real sure about, for soil before the problem...

advice- never grow a plant in the sink ;P whats the numbers on your nutes? npk amounts? you mentioned feeding w/ nutes during every watering? if thats so it just maybe the case, generally you dont wanna nute every watering. personally in soil i use 2 on 2 off nutting schedule, 2 waterings will...

whats your water temps? dont want your water too warm. aswell youd want PH from 5.5-6.0. the PH youre running is soil based PH of 6.5-7.0. id definitely get PH down some try for 5.5-6 range. everything else seems a go. check them water temps making sure youre not too warm to breed algae or...

good question! i think everyone has a speculation to what happens at night, but as some people have mentioned, I also being one to veg 24 on 0 off as well as run normal 18 on 6 off cycles. on that note I personally think the only real thing that happens at night is the plants drink more. its...
