Nutrient Burn Help

Our AK-47 is showing signs of nutrient burns on two big leaves and I was looking for some help on proper flushing. The plants are in 5 gallon drums so should I just put 15 gallons of water in it? Do I put the water all in at once? What do I do after I put the water in? Do I have to do something to prevent drowning? Any help would be appreciated. Thanks!

just pour in the 15 gals slowly let it drain out the bottom and it should be fine. just make sure you do this when it needs to be watered to prevent over watering.

We only usually feed them 1/4 gallon of water at a time so I was just curious about 15 gallons being an over water and killing them?

no cause your supposed to feed them until you have 10% run off anyway so it will b e fine just make sure there dry first

OK, thanks for your help. I will try it next feeding

I was also curious what would happen if I left it untreated and just fed them pure H20 instead for the next few feedings? Will my plant die?

So for my watering today I fed our other 3 clones 1/3 gallon of 6.0 PH H20 and our AK-47 12 gallons Is there something I will need to do in order to dry it out? Also, when should I start feeding her nutrients again? It has been 6 days since they have received a feeding with nutrients, but the nutrient burn looks worse each day on the leaves that have it still. The leaf with the bad burn started shriveling up after the 12 gallons.

All of the leaves on AK have curled slightly downward. I won't have a camera for a few more days, but was wondering if anyone had any ideas on what is wrong?
