whats causing this ? ppm and low bud production

[Wohjew]

hi i got pics here some are of my master kush on 4x4 flood table and the others which are the reason for this post are on a 4x6 table . 1000w, 400 and 1000 over the 4x6 . the ones on the 4x4 are doing awsome they are at day 36 . the ones on the 4x6 are having some issuses , im assuming lock out of something this is my 4th try using tables , im happy with my results other that this defincey of some sort . this happend last grow to one of my tables , glad i ahd 2 . first of all , lol ive never flushed didt know i was supposed to . so im learning for next time . these are at day 31 only 5 days behind the others can anyone help where did i go wrong ? what can i do to fix this , how can i flush ? week one flower i started with sensi bloom AB @ 600ppm . plants are over 2ft tall x 16 of them , i also have a chiller and the ph has been fine . but the ppm would always drift up and id add fresh water to compansate . thanks if anyone can help

sorry the pics suck, the buds look tiny and are not forming . if i was to flush would nutes mixed at 300 ppm be ok ? i use R/O water too

is something wrong with my question ?BUMP

What is the PH of your water?

And if you say that you dont know, buy a PH meter and find out. Nobody can guess your chemical balances from sight...

why would i say i dont know if i wrote that my ph was fine in the post , i have tables lights chillers and filters . but ya i dont have a ph meter lmao ofcoarse i do ... ph is 5.5 to 5.9. ive started to flush at 200ppm hoping it will help , i didt want to wait any longer

Sounds like you are feeding them too much. The tops of the plants are perky which means they are getting plenty of ferts. I would flush and start at 300 ppm (half your original) until they start to eat and your ppm's lower.

im flushing at 200ppm and today the ppm is at 230 ppm . is this wrong ? what ppm should i flush with ?

...this is how I flush, if it helps.

I run flood beds, ebb'n flow style. General Hydroponics, floramico + bloom (Lucas Formula) for ferts....clearex and sweet for flush. I do my flush 2 weeks before harvest.

I empty the res, then refill adding "Clearex". I flood my bed for a constant 1 hour with the clearex....I empty the res again. Then I refill adding "Sweet" up until harvest...give it a try, works great! >>> https://www.rollitup.org/hydroponics-aeroponics/338720-lucas-formula.html#post4267692

ive been feeding at 200ppm and still its slightly drifting up . in this case what can i do ?

 

[trichlone fiend]

...empty res, refill with ro h20 and Clearex. >>> http://www.planetnatural.com/site/clearex.html
...after your 1 hour flood with clearex, refill with ro h20 and Botanicare "Sweet" ( I run sweet the last 2 weeks before harvest) >>> http://organic-hydroponicsupplies.thebigtomato.com/shared/StoreFront/default.asp?CS=tbt&StoreType=BtoC&Count1=836574733&Count2=753715157&ProductID=2214&Target=products.asp&utm_medium=cse&utm_source=googlebase

...then check your pH, make sure it's in range (5.5-5.9), or close to.
...only add ro h2o from that point on until harvest. Good luck.

i dont have those products or the 160 gallons of R/O for two res changes back to back . that seems like a waste . thanks for the replies . very good lesson learned here

Well typically people asking for help are having problems. They dont know what is wrong. So, when you said your PH was *fine* that didnt tell experienced growers much.

As it turns out it was a PH problem and you solved it, good for you.
