3 girl growing in same DWC system but different problems!

[devastator]

hi there


i have 3 plant in 1 dwc system but as shown in pictures their grow procedure is different !

one is bigger and healthy the other one is growing slow (seems healthy) and the other one has nut deficency !

what's the problem?! they are eating the same food and water !

i change water every week , i use white vineger for droping down PH ( 6 capful for 40 lit ) every 2 days

i'm in a damn island with no good soil and only have access to white vineger and a pack of 20-20-20 NUT !!!

besides , the local flower sellers gave me a nut that they don't know the % of N-P-K !

how often and how much should i feed these gurls with 20-20-20 mix?!

plz help me

can u tell me natural sources for N-P-K or other nuts ?

More information is needed. This could be a deficiency, or PH lockout.
Different strains, and even different phenotypes will have different requirements for nutes, and will often have different tolerances for PH fluctuations.
