Urgent Possible Deficiency help

Need help to diagnose possible deficiency in 3 of my plants which appeared suddenly. Brown discoloration and dryness of leaves. Also if possible advice on the correct treatment to apply please! Photo attached. All help and advice would be appreciated please.

questions ...how much water do you use each watering?
do you use a tds meter?
what is the ph?
If you water heavy the soil will take to long to dry with a plant this young...also it takes an hps of mh bulb to use lots of water.

Yerp...its over watering day on riu

Looks like ph fluctuations..how much and how often do you water?

Ph of soil is 6.5 and I always make sure that PH of water is between 6.4 and 6.8. Watered on the Wednesday and then only did full water again 9 days later on The Sunday

I water enough to have run off at the bottom of the plant. The ph of the soil is 6.5 and I make sure that the ph of the water is between 6.4 and 6.8. I don't have a tds meter.

Ok..how often are you watering and have your checked the ph of the run off? Just remember that just because your soil and water are balanced it doesn't mean they can't change when the interact...

keep in mind that when a plant is not fully using all that soil,as in still very short,than you need to throttle down the feeding and not pour in nutes until you see run off.
The water till run off deal is for full on roots and also the plant needs buco light source to eat that big gulp of water in the next few days.

Tds readings are too often over looked and this is the reason plants become exposed to toxic soil.

Only worry about the Ph of the soil if your bored and have nothing better to do, otherwise I think the plant looks fine. A little calmag and a little less water and your good.

Dont worry this Everything Is easily Fixable. You need to Water Without Nutes (Flush) Every 3 waterings. So 2 Times with Nutes, And Than a Good Little Flush To Even Your PH out and get rid of any Salts Built Up in the soil. I Suggest atleast give her A Half Cup PH Balanced Water WITHOUT Nutes. Leave the The Plant Alone till the Soil dries up and She will be healthy in no time! Also, I suggest Lowering Your Nitrogen Levels, The look very High... Keep going, You'll get it!

"Dont Worry About The PH Unless You're Bored" ??? He needs to correct the PH and stop feeding nutes every watering.

You need to stop giving ridiculous and incorrect information. How do you know hes feeding every watering? Where does he say that? His leaves are a perfect green meaning he has a perfect amount of nitrogen. Flushing after two feedings, bahahahaha, you go ahead and do that with your plants but flushing is super stressful to plants and shouldnt be done unless you accidentally dump a quart of nutes onto the soil and its last resort. Worrying about the pH in soil is a crock of shit as well. I wasted more time money and energy on that shit and only did more harm than good. Since I stopped giving a fuck Ive never had a better plant. Stop googling answers to threads, we can all do that, people are looking for personal experience. So sit back and relax with your 2 big bad posts and learn something.

People tend to think flushing is drowning the shit out of your plant... That is extremely false! Flushing is you trying to slowly and evenly remove excess nutrients from the soil that the plant is not going to be using anymore. Just because flushing rhymes with rushing, doesn't mean they go together. Why do you think a good flush takes 2-3 weeks?

DabFather said:

You are sadly mislead on your techniques/information. Maybe you should take a note or two as you read along! If you use a too high of nitrogen levels, you also increase the soil's mineral salts in which case takes water away from the plant while leaving the salts behind. As a result, the leaves take on a burnt look from dehydration. Leaf edges become yellow or brown and wilt. Flushing the area with water to remove the excess nitrogen is the best course of action to revive the plant.

That said lets talk about PH since you're so good at following along!
When the pH rises in alkalinity above 7.5, the roots are not able to consume the available iron, copper, zinc, manganese, and boron ions in their vicinity, and when the pH lowers into acidity less than 6 the roots are not able to access phosphoric acid, calcium, and magnesium.

Hopefully you learned something today... I would love a response!

Ive learned from the best here on RIU. Im not trying to shit on your parade buddy but micromanaging the way you explain is a good technique if your growing hydro. Im a seasoned soil grower and used to have the same mindset as you as far as micromanaging goes until I started taking advice from some really experienced growers on here (who have the product to back up their advice), and never had a better crop. Grow how you wish but you will soon learn the ways of RIU. Welcome to the forum.
