Budding...and big problem

Hi im 2 weeks into budding and my plants seem to have maybe a bug problem or a nute problem or maybe this is just natural this is also my first time growing.

my room has a 1000 watt mh, using B-52, Sensi grow/bloom at 400ppm and im using a dwc each plant has its own res with about 30 litres in each res. with 1 12" airstone in each res and i check ph daily keep it at 5.5 and let it go thru the cycle to about 6.00 before bringing it back down 5.5 and i change the res. once a week.

i just recently went to home depot and got some insect spray and treated my plant once every 2 or 3rd day. and it seem to stop the spreading but im still not sure.

here are some pics but mind you ive been cutting off the dying leaves daily which i know i shouldn't be but i cant stand to see my plants like that.

i looks like there burnt or they may have a deficiency,,i dont think its bugs,,are the roots looking healthy?

umm well alright i soppose its weird the roots were white then went a little brown...then a whole shit load of new roots grew and white as hell and furry(also used tarantula beneficial bacteria occasionaly). i used the sensi grow with no problem it grew like crazy with no problem it just seemed to happen like a week after changing the light cycle and changing from the grow to the sensibloom.

here are some more pics...

and a few bud pics too
of my unknown strain

You might need to slow it down on the nutes. Your going to want to flush them by the last week or so anyway. Are the yellow leaves all over? or just on the bottom?

the bud still looks good too....

wouldn't worry about those fan leaves the plant is probably taking nutrients it needs from these leaves as long as the buds are forming properly(strain dependent) this may well be normal 400ppm is not a heavy dose of nutrients in my experience good luck

Ya just the fan leaves underneath and in the middle stem are turning yellow but the buds are looking great...all the colas with alot of bud producing are basically all green.

My water after i let it sit for 24 hours has a ppm of 185-200 and i add a premix of all my nutes in a 1 gallon of water until desired ppm. could it be because of the hard water? and the final ppm of 585?


Here some more pics

Update,

woke up this morning and found these 3 leaves i dont think its anything really harmful because they were all at the bottom of the plant, but i'd like to know what you think about the fan leaves?

Deficiency or what?

something you might want to keep in mind, is that when the leaves curl down at the tips like yours, that's a sign of overwatering

ok...little confused about that one though how would i correct an over-watering issue when i use a DWC?

i use 12" airstones pumping oxygen for each resevoir which contains about 25-30 littre( fill about 1.5-2 " bellow my pot).

Doesn't the whole hydroponic thing eliminate the over-watering issue.

it could be a phosphorus deficiency,,,,explains the grey colour leaves,,,,

You can still experience over watering in a DWC it's actually lack of oxygen so the the roots can still suffocate. I'm not saying thats whats going on but it could be. I've never done dwc but I hear the general rule of thumb is 1watt (air pump) per gallon. Maybe the 12" stone worked well when it was younger but know its just not quite enough.

Good Luck

When flowering a ppm of 500 or so is very low. I keep my plants around 900 ppm.

Looks to be a build up of "N".Are your leaves curling up like a "rams"Horn??? I'm having the same problem.Flush them good

yeah it eliminates over watering....it just lookes like nute burn to me, and that happens to the bottome leaves towards the endo of flowering, as its concentrating all its energy into making nice fat buds that make your nose bleed...if thats the only problem is those few leaves, maybe flush if you think its a big deal and a little less on the nutes...but i wouldnt worry to much about a couple leaves, buds look good....thats all that matters...lol

the darlings look just fine from here my eyes are turning red just lookin at em
maybe back off on the water or add air if in hydro GG

depends on what's making your water hard a background of 300ppm doesn't seem that excessive unless it is sodium or something water can be purified before using boiling and letting water sit for 24-48 hr then siphon leaving sediment in bottom there are other more practical ways on the net probably GG
