i KNOW somethings wrong

the water schedule for the outdoor ones is every 3days, half gallon of water each and ever 3rd watering was with the nutes. if they are in flower shouldnt N not be an issue, flowering just needs the P/K right?

Your statement is the most common misconseption about growing mary jane, contrary to what these food companies want you to believe mj still gobbles lots of N during flowering.. What do you think is gonna feed the plant in order to make all those new leaves?

so i need more N for which plant? one is starting to flower but the buds arent swelling, even after 6weeks.

the other just has yellow and long skinny leaves.

I always keep my N higher until around the 4th week of flowering. Is the one that's taking forever to bud a sativa?

IMO this plant gobble more N in flowering then in veg. Defs show up waaaay quicker in flowering also

Nutes will lower the ph. You should really have a ppm meter if growing hydro.

But it looks to me that you are having some deficiencies that more nutes would cure including mag def. I bet that your ppm's are low but you are going to need a meter to be sure. My bet is they want more food.

I had same problems.u should flush them with fresh water for 2 days then u will add nut in middle only u should have ppm result if not u will have problem in flowering priod and it too bad
best wishes

the 2nd pic im not sure what it is. it was a bagseed im thinking indica since it has long skinny leaves.
the first pic that has the buds that seemed to have stopped filling out is a godsgift strain.

Indica=short, beefy and big fat leaves, couch lock high, sometimes better for pain. Shorter flowering time 6-8 weeks
Sativa= Usually skinnier longer leaves, longer flowering time, uplifting high. Flowering time usually 8-12 weeks and some up to 16 weeks

is this for nft and bubblers.????? iv asked this question b4 and been told keep ph @ 5.6-6.0 ,,,

If you are using a hydroponic system, the water's pH should be kept between 6.1-6.3, which is mildly acidic. When rockwool is used, keep the pH at the lower end of the recommended measure to counteract rockwool's strong alkalinity

ph between 6.5-7 (only have access to test strips which are color coded only)
nutes are GH flora series on normal veg schedule
lights are 8x 26w daylights cfls.
each plant is self contained with an air stone in a half gallon pot. (small i know)

i cant really +/- the ph with anything so i just run it through a water filter 3-4times until the test strip hits around a ph of 6.

Sorta looks and sounds like Mg deficiency...

Magnesium is a component of the chlorophyll molecule and serves as a cofactor in most enzymes.

Magnesium deficiency will exhibit a yellowing (which may turn brown) and interveinal chlorosis beginning in the older leaves. The older leaves will be the first to develop interveinal chlorosis. Starting at leaf margin or tip and progressing inward between the veins. Notice how the veins remain somewhat green though as can be seen in figure 15.

Notice how in Figure 16 and 17 the leaves curl upwards like they're praying? They're praying for Mg! The tips may also twist.

This can be quickly resolved by watering with 1 tablespoon Epsom salts/gallon of water. Until you can correct nutrient lockout, try foliar feeding. That way the plants get all the nitrogen and Mg they need. The plants can be foliar feed at ½ teaspoon/quart of Epsom salts (first powdered and dissolved in some hot water). When mixing up soil, use 2 teaspoon dolomite lime per gallon of soil.

If the starting water is above 200 ppm, that is pretty hard water, that will lock out mg with all of the calcium in the water. Either add a 1/4 teaspoon per gallon of epsom salts or lime (both will effectively reduce the lockout or invest into a reverse osmosis water filter.

Mg can get locked-up by too much Ca, Cl or ammonium nitrogen. Don't overdo Mg or you'll lock up other nutrients.

Magnesium toxicity is rare and not generally exhibited visibly. Extreme high levels will antagonize other ions in the nutrient solution.

UPDATE! turns out that the first pic posted was just from not enough nutes being used... well i up'd the schedule to the agressive veg and everything was going fantastic until the other day... and it went from this:


to this:


i havent changed anything!

its currently on aggressive schedule with general hydroponics. the ph is around 6ish. one of the plants already completely dried and shribbled up from looking like this. i changed the resv for each plant once a week. and when its low i just make another gallon recipe and add to it. it has 10x 5600k 26w and 2x soft white bulbs.

thats Phosphorus deficiency in flowering

aggressive schedule?!?! you need to feed with a ~balanced npk ratio.

yea GH has four different schedules to go by and right now im in the aggressive schedule which consists of 10ml micro/5ml grow/5ml bloom. so i should start adding more *grow* into the mix? and can a P def cause a plant to die? because i had another one that started showing these symptoms and within 48hours it dried and shribbled to death. the roots were all brown and smelly too.

it can over time but it just sounds like u has some serious root rot

what causes root rot? just the warmer temp water? the grow method is bubbleponics and everytime replace the resv i always use water thats been refridgerated and i ph down it with vinegar until its about 5.7-6.3ish then i add the nutes and give it to the plants. i was doing this routine for about a month before these defincientcies came into play

A lot of people over do it with feeding. Hydro is super sensitive. Less is more. Or - is your top feeder clogged and the small roots aren't getting water on top?

i dont have a top feeder, its a dwc with an airstone.so should i flush out the plants and just use ph'd water alone until it clears up?

another planted started wilting like phosphorus def and had started to dry and shribble...

you got root rot in there definately mate, if you havent sterilised everything perfectly it will hang around for years, gave up with my bubble pot, root rot everytime.

is it contageous to other plants? will peroxide help?
