Nutrient burn with organic nutes

hey guys,

So I’ve come into an issue with my outdoor this year. I mixed in some supersoil with the bottom 4 inches of soil in my 20g pots. Transplanted and then topdressed with a couple tbs of a 5-2-4 plant food I use. Other then that I’ve used nothing but calmag and water. Unfortunatly I began noticing a burn shortly after transplant. At first it looked like they were still hungry because it was the lowest leaves so I gave a little more topdress which was a mistake because the next day i began getting some yellowing towards the middle of the plant and getting leaf tips curling Dow and burning. Not sure how that extra amount of topdressing made it so bad. My question is because it’s not synthetic nutrients and it’s iust all topdressed and what is in the bottom of pot. What’s the best way to get the excess nutrients out? Just large amount of water through the pots? Should I water more frequently to try and get some flushed out. Plant should start stretching really good now and I want to be able to get them ready for flowering but need to make sure they won’t keep burning.

Thanks for any info

What kind of plant food do you use? Does sound like classic N burn. It is possible to give too much even if its organic. Either way watering as normal is usually the fix. I wouldn't try to saturate the pots but if you happen get alot of rain that might help. Too much NPK can even throw off ph temporarily but the soil will buffer itself in time.
Try using a slower release form of npk like organic spikes, fertilizer, and/or compost for next time. Check for an OMRI label when looking for fertilizers. 20 gal of active soil should have enough npk to sustain your plants unless they are monsters. If they are getting pale and need fast soluble npk try something with lower values like say 2-3-1 liquid fish.
It is always better to add what is needed to the soil before there are plants growing in it then it is to try and give nutrients to correct a deficiency. Amend/recycle the soil next season and then just give water as needed. Watch the newest growth to see if your plant improves over time.

Thanks man I appreciate the reply. So I typically use promix bx for my outdoor. This year I did that and with it I mixed in some of the coast of Maine platinum growers mix into the bottom couple inches. Then I topdressed with a couple tablespoons of the coast of Maine stonington blend plant food. I’ve used the stonington blend for a couple years with no issues but I guess I misread my plants when I saw some lower yellowing and those extra Tbsp on top combod with the supersoil was too much. Other then the soil I mixed into the bottom I didn’t add anything else to the promix. I wasn’t planning on being able to do any outdoor this year so I hadn’t mixed up a soil and then things changed and I was able to get some girls going. Just trying to get some of these excess nutrients out as quick as possible so I can try out this new flowering formula. Been trying to watch new growth and keep an eye out for any new damage to leaves. I last added the nutrients to soil on the 26th. I have watered twice since then.
