Hydroponic deficiency (URGENT...PLEASE HELP...)

hey guys
these are my babies, growing in hydroponics,PH is being monitored, 6.5-6.8 all time,and also Temp is pretty under control...

first 2 pics were the early signs and since last night their started getting worse and worse. can anyone help me with my issue...as you can see the shoots started growing but they are also very light green...

gave them some epsom salt last night tought it might be mag-cal def...
any further ideas????

what should i do with them nw??? shud i top my plants???



need some urgent help...pleaaaase help guys...

Get the ph to 5.8 and things should improve ,also make sure temps under 80.

yep ph is too high for starters. 5.5 to 6.3 is the range for hydro imo

edit:- to be clear you should drain your res.
then flush with ph'd water for an hr or so.
then drain res again and run some nutrient solution at around 300-400 ppm.

after a few hrs or tomorrow morning check your ph and make sure it is still ok.
also check your ppm if its rising you are feeding to strong. if its falling your plants are taking in nutrients and all is good. just watch your ph and they will come good.

woooow...tats messed up...all this time i ws trying to keep 6-6.5.....
i'll fix that...but the issue with ppm ia that i dont own a TSD Meter, so i tought i can kinda figure it out....
alsoo dont have actual hydroponic Fertz,as it not available in d country im living in...

i know its really ambitious to do such thing, but here i am....
gonna try flush them tonyt as "2easy" suggested....what should be the PH for flushing????
the ferts that use are straight Ndrops and KP drops, and for the micro ferts im adding little bit of a tomato fertz i got....i cant add too much of that as it raises my Ph like crazy....
for a 20L i added 40ml on Ndrop and 30ml of PK drop...is that too much????
im a totall noob in this shit...
much tnx for responding...

happy smoking...

ohhhh noooo...dont tell me its to late man....cant i jus top them maybe???
and wait for the shoots to grow and mayb clone them????

it doesnt look to me like your overfeeding but i really am not familiar with your ferts so im not sure. if you everfeed the leaf tips will go crunchy and look burnt, your leaves will start to feel papery not soft like they should be.

i would probably keep feeding what you are now and just focus on the ph. once you get that sorted out then we can work on everything else.

there not too far gone yet i dont think. the good thing about hydro is although problems can happen quickly they can often be fixed quickly too.

sulfer deficiency... or maybe iron deficiency, get out your blender and add water+ some egg shells

flushed them last night,and the ph is flat 6.0 nw...havnt add the fertz yet, gonna be adding them back tonyt....is it correct...???

im sure its too soon to tell,but i think it stopped the disease sort of...fingers crossed...
tnx guys,will update u guys more,also bought a DST meter online...hopefully will be here soon...

cheers...

yeah give em a feed and keep an eye on the ph. then just watch the new growth and see what it does.

How many ppms? Are you checking the ppms? Could you be giving it too much of something? The first two pics the really yellow new growth is the first sign overnuted too many ppms your frying it I'm no hydro dude flush lower ph and ppms but it could be too late

this is total bullshit.the yellow growth is from lack of nitrogen due to ph being so high. yellowing is never a sign of over nuted, burned tips and clawing are signs.and no it isnot too late, very easily fixed. for young seedlings and veg keep ph at 5.6-5.8. if you need help and want useful info, pm me, all i do is hydro.

Moderator? What are you trying to do to this guy? We are here to help with marijuana problems, not make omelettes.

Im going to have to agree this is a ph problem, get it down 5.5-5.8

as everyone said bring that ph down. what are you temperatures lights on and off? What kind of lights are you using? It looks like overheating and the burnt top looks like it was inches from your light
