Please help before my ladie die

[Whiskers]

First time grower and poster:my 8 days old ladies started germination with ronin way after saw first roots and real leaves transfered to 150x150x180 cabinet 5,4 gallon dwc bucket with bottled water(ph'd),under the mars reflector 192x5 germination mod on 24 hour,rh %60 heat 21-25 C,using resun lp-20 air pump(22L/min or 1320L/hr) for 4 bucket system,have a little fan inside,downstair stealth grow not have fresh air inside daily.

after first water only week started to An grow A and B 12ml,Cal-mag 12ml,B52 18ml,Rhino-skin 18ml,voodoo juice 18ml for 3.5 gallon water.

in this conditions ladies started well but the end of the week one of the blackberry kush auto's leaf started to get light yellow/green colour from the center of leaf to the sides and lemon haze auto have scars peak of leafs after research i think lemon haze having cal-mag issiue but i couldnt understand blackberry kush's problem need professional eye on this.

first day of the fertilizers i saw blackberry kush's leaf like this.

Thnx a lot already

please take a picture in natural light. It helps with diagnosis.

Can I get a close up of the leafs please

 

[Whiskers]

Sure, i can not take good picture of curved one.

:smoking: Whiskers....looks like you had a temporary pH snafu, which could cause several possible problems, often more than one if it persists.. but new growth looks fine, so that's the good news! In DWC, everything happens so fast, usually with symptoms that can be muddied for diagnostics because of these reasons... what I see on those lowers isn't anything distinct, but I've seen this same thing before under similar circumstances... what matters most is the newer growth looking good, but those first true leaf sets might dive out anyway at this point,...
DWC as a new grower will be a challenge, mostly with pH/nutrient management; just keep a daily eye on the pH, testing often enough to see how it drifts over 24h period.. this way you can get a feel for it's stability.. mind that as the roots get bigger, changes will happen faster as the plant alters the chemistry dynamic in there! Be sure you pH meter is calibrated, cleaned and stored in the respective proper solutions... dirty, off calibration, dry stored meters will give inaccurate readings...

Thank so much to all of who viewers, @briman ,@Bailey for your interest and @Waira being a good master splinter :smoking:

Ph in 5.8 to 7.5 range 24 hour period every day using gh ph down ,trying to keep ph meter clean but i dont know how to calibrate

Using this meter

Same meter as me a fleabay special mines works a treat mines came calibrated but u can buy a pH buffer wich is set then there a small screw on the back turn it till it's the same as the buffer and ure done

-Ah! if your res' went up that high in pH, that's the problem! 7.5 is waaaay off, and causes instant trouble.... check out this nutrient availability pH chart--

.. yes, you will need a pH calibration solution, 7.0 at least, and the instructions for doing calibration with your brand of meter.... there's probably a storage solution for it as well, and always rinse with distilled or RO water before and after use and storage,... it doesn't take much for these meters to lose accuracy, or get damaged... and in hydro, you cannot afford that! I recommend getting a TDS or EC meter as well,...

I couldnt answer because of internet connection problems,after long treat ph stabilized 5.8 to 6.2 max 6.4 my ph meter came calibrated and have ph buffer inside after you guys directions checked with ph buffer and still calibrated ladys happy and healty for now.I will update new photos made so much research and didnt understand how TDS or EC works and how to use it.by the way want to ask another thing saw a lot of article about heisenberg tea to protect your plant from sickness and bad bacteries i dont have acces materials to make heisenberg tea is it necessary if it is how can i make a thing similar to heisenberg tea ?
