how to stop nute burn

[popsson]

i put fert and epson salt on my plants... now i noticed that the lil round leaves (plants 2.5 weeks old.)on a couple of the plants started turning a bit brown. i think its nute burn. what could i do to stop the progress of this nute burn?

A 2.5 week old plant does not need to be fed. If it is nute burn, flush the pots with water. If you have a 1 gallon pot, a flush would be giving it at least 2 gallons of water. It is normal for the little round cotyledon leaves to eventually brown and fall off by the way. What type of soil are you in?

ooo ok. then i think it is just the round leaves dying because only a couple of them are turning brown.

what if almost every tip is burnt (even the new growth at the top) and lower leaves drying out and yellowing? Plant (clone) is about 3 weeks old in my home but was purchased from a club and the tag says 5/15 so I believe it was cut from the mother plant on that date, which would make the plant about 1 1/2 months old. 123 watts/6500 lumens one inch away

smknvtec says it all

you need to flush your plants since you foliar fed them i would spray them with water, but i dont know if that will do any good or not since you foliar fed them

if you watered them then you would have to flush the soil out with alot of water and wait a week 1/2 and feed 1/2 strength if its chemical nutrient

what fert did you use to feed your plant and how much

I have the plant in rockwool and the GH nutrient schedule said in week 3 to give 12ml Grow 6ml Micro 3ml Bloom. The bottom leaves were in bad shape before mixing this new formula as the plant approach week 3 1/2. I fed it once with that solution but realized it was probably too much. For about 4 or 5 days I have only given the roots water once but making sure there is still dampness at the top and bottom (wetter at the bottom) I have also been foliar feeding them a triple diluted version of the nute solution listed above.
