Well if it is I have Epsom. I'm worried because it is the new growth being effected.

Do a full flush. Feed it Epsom and some nitrogen to stimulate more new growth. Luckily this can all be fixed, good thing you caught the problem early.

its common practice to leech soil.

if plant is in 3 month old soil, it should have been leeched once each month if using nutrients.

leeching is pouring 3x the medium size of water into it. example 3 gallon pot gets 9 gallons once a month, this cleans off the roots and allows you to lay back into nutes and is a good practice

Hi.

I've been a grower for over 2 years and have never heard of this "leeching" thing. This sounds quite interesting.

Yes, he is describing flushing, just using a different term. If growing organically there is no need to flush monthly, but with chemicals in an extended grow it is probably a good idea.

Yes,I would do a flush.
If my plants are showing signs of overfeeding,this usually happens to me when I grow a new strain and the plant will tell me if I've used too much of the nutes.
I just do a flush and it works itself out.
Don't forgget to dilute your nutes as well or you'll just end up with trhe same problem.
Peace

Magnesium deficiency starts at the bottom of the plant. With green veins and general yellowing.

your lower canopy looks lush and healthy to me. Though, the crispy taco curl ups on the damaged top likely indicates light/heat stress.

also I do not see that your plant is overfertilized/ nutrition burn...... There are no burns to the end tips of the leaves in the lower canopy. Also nitrogen toxicity shows a dark green downward claw, also of which you do not have.

dont take my complete word on it,a s I am a fairly new person around here. I would love for some veterans to comment on the diagnosis I provided.

I have learned ( correct me if I am wrong ) that this assists in releasing the salt build up in the soil. So once again the plant can continue consuming nutrients as it should. But...... Wouldn't this particular cure be for symptoms related to general broad deficiencies? May I ask what deficiencies you see in his plant to warrant this treatment?

sorry, kinda new myself and would appreciate your insight.

Well,since it's happening to the new growth and some of the fan leaves then that would most likely indicate that the nutes are too strong,not diluted enough ,which ends up burning the leaves.

So to clarify nuts burn happens only on new growths?

i went and re-read https://www.rollitup.org/marijuana-plant-problems/216537-self-diagnose-your-plants.html again and let me ask you all this in debate then....

Q: if this is Nute Burn?
what about the amount of damage seen? Given that the top of the canopy looks fairly destroyed, wouldn't have this issue been going on for some time. Would you see the classical signs of Tip-of-the-leaf burn also on the lower canopy? Even a little?

Thanks again for the continued response. I am curious myself now!
ORIGINAL POSTER: can u give us some info on your lighting setup? And/or feeding schedule?

Looks like you burnt it with the light, heat stress of some sort, or pesticides?
I agree here. Could be root rot/damage too.
Imo, never flush soil unless you are sure its a nute burn. You will destroy the soil by removing all the good micros. Instead, water with a small runoff every time (like 100-200 ml) to pull excess salts out and oxygenate the soil.
If you are not sure if its nute burn, repot is better than a flush.

Thanks for all the input fellas I'm sorry I took long in responding. This plant was on 2 14watt 5000k for a 24 hr light cycle. The plant has been in room lighting for about 1 week now because it out grew it's Grow Box. She is only been getting ambient room lighting consisting of 1 14watt 5000k @ 8 feet from ground. It sits in Vigoro organic potting soil and as I'm ashamed to say it has been fed MG veg since seedling, always BG with first distilled water and then spring water. I adjusted the MG to water ratio gradually on the fly and was shocked that she turned out so good for a longtime until now. I flushed it with 15+ gallons of tap water which I have no idea what the pH is about 3 days ago as it always was watered with distilled and or spring water. This is how it looks today,
