Nute burn/deficiency. Any help?

Its been 3 weeks since the girls sprouted. 6 days ago after coming back from a weekend trip I notice that the plants was showing some signs of nutrient burn. Flushed both and 3 days after the burning stoped. After that, 2 or 3 days I notice that the flush took almost all nutriens that have left on soil and the plants was start to fade a little bit.
So a water with 150ppm of Biothrive grow and 100ppm of cal-mag.

2 days passed and the new grow seems to be good. What you guys think?

If you asked a week ago you would have gotten a lot of responses. Problem solvers are either distracted or taking a break for a couple of days. Anyway if the new growth is coming in good and the other deficiencies stopped progressing you should be fine.

Thanks for your response.

3 days have passed and the new growth seems ok, but they are showing signs of deficiency or they are just recovering from the nute burn?

I dont know if they are still burning, or hungry at all.

My guess is that after the flush they were recovering from burning but in the same way start a def.

Is that possible!?

As Buba Blend said...if the newest growth is doing fine then you're doing fine.

Before your week-end trip they were doing good right? You've flushed the plant and basically starting fresh with the nute. Instead of panicking and trying totally different at this stage, continue what you we're doing before this problem. See if you can replicate the problem, that's the only way to find out what's causing it. While your doing what you were doing before, check the ph run-off (its possible you have some sort of lockout). If you notice some tip burn or spots in the new leaves and your ph run-off is good then you might want to dial down your nute. It's all about ph and the right amount of nutes.

That's just my opinion.

Yes, they were. Everytime I water I ph the water to 6.0 but the runoff always comes higher like 7 - 7.2.

The last time I watered with 5.8 ph. but didnt check the runoff, Waiting for the next watering.

Like you said I will let her do her thing and wait the pots dry. after I watering will check the ph.

Thanks for the input buddy.

put a thermometer in the dirt, looks to me like you have an anaerobic issue. You over watered before you left and some anaerobic stuff took hold. This is my first theory

I will try that but I dont think I ovewatered at all. I always let the pots dry out well before water again.
Also if you take a lot at the new photos I transplanted the plants and the roots looked really good, clear and white.

Lets se what happends next.

Thanks for your help bro!

That definitely looks like nutrient burn to me. in soil i dont measure ppm and just generally go with half strength of whatever nutrients i think my plants need unless they ask for more.
Its a lot easier to fix deficiency imo than toxicity. you get toxicity of one thing and all of a sudden 3 other things are locked out and your trying to supplement more to fix that and then things just get worse

Old burn. New growth looks healthy but I think I'm seeing mag def so hit it with Epsom salts @ 1tbsp/gal and spray directly onto the plant for fastest absorption.
Alternatively you can mix 1 tbsp garden lime/gallon and drench. (Water in)
Otherwise you're good to go.

Thats exaclty what I think it happened. Thanks for the input. I will let her alone and just give plain ph water for a bit. maybe spray some epson salts if mag def increase.

Hey Danny, I have some epson salts here, I will wait a little bit cause they are recovering from a lock out. and if it spreads I will hit them with epson salts.
