Ebb and flow,flowering,need help,PICs

this is a ebb and flow table 9 days 12/12 white russians and DP euphoria,they were veged for 2 weeks to about 1.0ec then i started flowering moved the nutes to 1.2 to start with then in five days to 1.4 and now i got to 1.5 then i put 10g of epsom salt that got it to 1.6-1.7ec,they started showing these signs of deficiencys so thast why i raised the nutes,ph stays from 5.7-5.9,are these burn strips nute burn,and the new growth started curling a bit and the tops are yellowing from within,im confused

looks loke nute burn to me. When i started jacking up the bloom nute my tips curled like that for a week or two thil they grew strong enough to handle that high of nute. Besides the plant is only what 3 weeks an change old. Id say you should still be at about 1/2 to 3/4 reccomended strength. Also im not too sure about adding epsom to ebb and flow...

flush'em for 2 days with plain PH 5.5 - 6.0 water. after that add just lil bit of nuts. LITTLE BIT. and keep raising until EC 1.4
see if they like it that much. NOT ALL THE PLANTS ARE THE SAME

and instead of epsom salt, go buy some cal-mag from your hydrostore. i used epsom salt untill i did some more research. it can lock up your salts even more and can cause an intoxication

i got cal-mag,i just didnt whant to use it yet couse on the fert that im using says it has plus mag. and the tap water has some too and calcium,my tap is 0.5ec,can u tell me can i dilute the solution to 1.0 or 1.2 ec and start from there couse i have a 3 400l reservoirs so im trying to keep the water flow to a minimum,

what kinda nuts are u using?

its a mix 50/50 of 13-40-13 and 3-11-38 u wouldnt know the brand its a domestic product,i live in europe.i move the nutes to 1.2ec today see how that goes for the next few days,this looks different from the nute burns that i had in the past when i was growing in soil,theres probably some lockouts with it the new growth id twisted and the edges are gray and half dry,is this normal when u run the nutes too high to have a lockout or im i missing something

and before i burned them the midle of the leaves on the new growth was yellowing from within something like this on the pic./thats from the sick plany quide for cold temps during the night/ but the temps in my growroom are 22-24c day,18-20 night, can somebody tell what is that

That's a sulfur deficiency. Add some epsom salt, but not to much coz you can lock up other nuts.

take a look to this http://www.greenmanspage.com/guides/nutrientdisorders.html

i did add epsom salt 10g per 350l it raised the ec by 0.1-0.2,but then they got burned,on the fertilizer i couldnt find any sulfur so i thought can i add sulfuric acid as ph down to compensate for the lack of sulfur

i'd do a flush, they're probably locked

From my own experience i dont see the advantage in feeding high amounts of nutes
and 'pushing' my girls. ive never yielded anymore by using more nutes and have less probs with nute burn.. still, each to their own.
Yeh give them a flush, sometimes it can take some work to dial a strain too (especially ebb n flo/nft, its better to do things gradually bcos the plants react alot faster..imo.

well put ^^

yup, if you burned them, then its a lock somewhere. flush'em.
but don't forget: a deficiency stars another one ...

im using alot of water 350-400l so can i lower the EC to 1.0 like i did today would that help so i wouldnt need to waste all that water ,or would it be better to put fresh tap water and for how long would i run the table with fresh water before mixing nutes and when i mix the nutes what EC mesure should i start with after this burn

Wot media are u using? u have pots on a table right? Id flush fresh PH adjusted water but if your worried bout water consumption
then leave it at 1.0 and watch the new growth, maybe they will adjust themselves, prob not cos i think ur locked but you can try..
Start nutes again at woteva level u want, now u have some experience on wot the plants like now so ur the best to judge.. and dont stress, this shit happens

for how long should i flush with ph'd water before adding nutes in it,i run the pump 3times during lights on and 1 during the dark

keep it just ph'd water for a few days, then ween the nutes

why do you water during the night?

what EC should i start the nutes at,my tap is 0.5ec and on another table that i just started flowering a week ago i keep em at 1.2-1.3ec.is 0.8 too high and should i raise the nutes daily or every 2-3days

i dont know i hear alot of people give a watering during the dark cycle maybe to keep the roots from drying out,my plants are in perlite
