You should include this information in your grow journal as well, other growers may be able to offer advice. Your leaf damage appears to be a phosphorous deficiency. Have you fed your plants any nutrients yet, if so what are the nutrients that you have used and how many millilitres per gallon are you feeding? What are you adjusting your pH to?

I believe you have a nutrient lockout. I would adjust your water to pH 6.5

ok i will adjust it to 6.5 next watering can u please recommend a good npk for veg and for flowering cause im using 20-20-20 i think too strong. i dont live in usa so plz give me a ratio not brand to check if my guy got it.

thanks for your help

 

[lebgrow]

do i need to flush those plants with 6.5 water or i just water them from now on with 6.5 and my next scheduled fertilizing is 14th so i use 1/3 tea spoon in 2 liter and adjust the water for ph 6.5?

 

[lebgrow]

please provide best % of npk for veg and flowering and the best quantity in 2 liter for those ladies they are 1 month old

You should probably google your question as I don't think there is one firm answer. Different folks use different ratios and have found what works best for them. Your Nitrogen will be your biggest variable between Veg and Flower though

Edit: If you go with a major nutrient company they will have a calculator on their site where you can see the requirements based on your container size, just be sure not to go full strength at the start or you'll nuke the plant.

 

[lebgrow]

so what should i do flush the plants with 6.5 ph water and feed them 14th with npk and some zink magnesium etc...?

 

[KingJohnC]

I would flush your pots with pH 6.5 adjusted water with at least twice the volume of water as pot size or until the runoff pH is the same as the input waters pH. I recommend you start to feed your plants 1/4 strength nutrients and progressively over several waterings increase the strength until you are using full strength nutrients.

So I flush them tomorrow morning with 6.5 ph water and will furtilize them on the 14th wait till 14th so ths soil will dry for a bit? And I should add npk and zink etc few times in my future watering?

Does your N-P-K formula have any micro nutrients in it? What micro nutrients are in your micro nutrient formula and does it have a ratio or percentage that the nutrients are in?

no it doesnt have micro nutritions well i dont know the percentage of my micro nutrients i asked aspecialist about zink copper etc he gave me a ready mix bag

 

[lebgrow]

is it ok if i flush them now 1 hr before their 4 hrs dark period or i wait till tomorroe morning

 

[KingJohnC]

Yes I would flush your plants now. You may want to discontinue the micro nutrient feeding and purchase a calcium and magnesium supplement for your plants.
