Live Stoner Chat Do seedlings recover from nute burn well? Or does it feck em? (Autoflowers mainly)

Heres my baby who ive put in hot MG soil not thinking properly

Just wondering as flushing is not an option how long it will take before she picks up or is she buggered?

Thanks guys

How old is she? Normally they don't take stuff like that very well in that age. About 2 Weeks ago i chopped a Dinafem Cheese Auto and a AK47 Auto that got stunted that size, and they only reached about 1/10 of the normal size. If I were you, I'd try to promote root growth as much as possible. Mainly by Mycorrhiza and Root Stimulator, I would not feed much at all, just slightly elevated levels of phosphorous ( change to P:K = 1:2 about 2 weeks into flowering ).

Maybe she'll pull through, you never know. I wouldn't flush actively with much water, just use plain water with a slightly lower pH until she recovered, and only start feeding if she shows miniscule signs of deficiencies. If you don't got any way of measuring the pH of the water, just use about 5-10 drops lemon Juice on 1 Litre tap water, or about a half teaspoon lemonjuice to 1 gallon tap water.

Does bringing the ph down help nute burn bro?

 

[Super Mario]

We'll not with the damage that is already done, but a lower pH increases the water solubility of most nutrients, and in turn more gets carried away when watering. That's why it is advisable to watch out that a little bit drain runs out of the bottom of the pots for now ( similar like you do in coco ), but try to keep em a little drier afterwards.

so basically the slight acidity will flush out the high nutes more?

Yep and a high pH decreases solubility in water, so it is possible to lock down nutrients in the soil, at this range the nutrients are not available by the plants though. So the key is to stay in the optimal range. Water solubility is directly proportionate to plant availability of nutrients with very few exceptions ( immobile heavy metals that require stronger acids ).

Basicly if you dissolve a nutrient salt in water, it dissociates into two oppositely charged ions. The free dissociated ions can rearrange differently, if you got a free charged ion of a alkaline element in solution ( like Calcium,Magnesium, Potassium, Sodium ), it will combine with acids ( Sulfuric,Nitric,Phosphoric and Citric acid for example ) and form a salt, which is in most cases of higher solubility and availability. Which goes where is determined by Electronegativity. https://en.wikipedia.org/wiki/Electronegativity
