Deficience or ph?

[greenweed]

What is the fuck with my plants? I'ts a deficience or incorrect ph? And how I can save them? Tanks!







It is in 3 week of flowering(in the pics is in the vegetative phase) but the problem is worse! The stems become purple and the leaves turn to yellow with necrose, everywhere on the plant. I have 2 plants on 4 with this problem.

Please help me(and my plants).
Tanks.

you using any food? nutrients?

how often are you watering?
but it looks like a nitrogen deficiency, common in flowering when nitrogen is in low amount in the nutrient you are using to give to your plant.

you check the ph water run off too?
what soil mixture are you using?

 

[greenweed]

Tanks for your reply. Yes is like a nitrogen problem but i've give a 20-20-20 in vegetation without succes. The pH is 6.2, moisture is 50%, the temperature is 25 celcius degrees and I give them 20-20-20 in vegetation and 15-30-15 in flowering. Thank you!

how often have you been giving it and much thats the important part, you need to feed your plant weekly if your soil mixture is uised up the nutrients, the plant uses up nutrients and after 20 days you need to feed, that is if your soil mixture is good

feeding your plants once isnt going to solve your problem, you need to feed weekly

so the important thing is now how often are you feeding your plants and how much?

 

[greenweed]

I give nutrients always 2-3 weeks. But i think is a nitrogene deficient because the ph is too low. I think of losing my harvest at the point or they are. But I will try to give them lime it is the last solution. Tanks for your reply and your good interest. I wish you beautiful harvests! Tanks.

how much are you using? how much of the nutrients are you using?
i cant help you if you dont answer my questions, if it waqs ph issues your plant would show other problems

but have you ben testing the ph?

sorry but that plant loolks like its not getting enough food, it looks like your not using enough


every 2 to 3 weeks you are giving them? thats not going to work you need to give them food EVERY WEEK

you dont speak english do you green sand?

 

[greenweed]

Scuse me i don't speak english very good. But i try. It's a beginning. Ok i use a chemical plant food and i give every 2 weeks 1.5 milligrams per 2 plants diluate in 2 liters. I use paper strips ph tester. The PH of this solution is approximately 6.0 and the PH of the soil is approximately 5.5. The temperature of the grow room is 25 degrees celcius in day light and 22 degrees celcius when the light is to off. The moisture is 55%.

ok see thats your problem, you have not been using enough and your ph is low for soil

you need to add some dolomite lime to the top soil and add some fresh soil over it
use 1 tablespoon and sprinkle it around each plant so when you water your ph will start to adjust



you need to use 1/2 teaspoon per gallon of your 20-20-20 mixture

so that would be 2 ml per galon of water weekly
every week once a week you should use food

 

[greenweed]

Ok tanks i test it today.

 

[greenweed]
