No idea what happened

I was on vacation for a week. When I returned home this is what I found. It seems to be limited to the fan leaves.

@Dr.DankThumb420 is the same fly mining thing you mentioned on someone else’s thread?

@Astrocreep, got the same thing happening to my flowering northern lights , my ph is at 5.85 and won’t come up… Added almost 2 gallons of water at 7.1 and 7.3 and runoff is still 5.8/ 5.9… It most likely is phosphorus or potassium lockout in my case… Keep me posted if you come up with something… I’m basically waiting until my plants dry out and gonna hit them with 8 ph water to see if ph comes up

I am at a loss. I am running RDWC and I have a Bluelabs PH Auto doser set to 5.8. I had a friend check the status of the PH meter twice while I was gone. I have 4 plants connected to one reservoir. None of the other plants have these marks.

No I don’t think so. Im gonna say potassium or phosphorus deficiency don’t think its bug related… @ktreez420 @Donaldj @Majiktoker @Aquaponic_Dumme these guys can help on the rdwc setups

Manganese deficiency

Solution to fixing a Manganese deficiency
Foliar feed with any chemical fertilizer containing Mn., or mix with water and water your plants with it. Any Chemical/Organic nutrients that have Manganese in them will fix a Manganese deficiency. (Only mixing at ½ strength when using chemical nutrients or it will cause nutrient burn!) Other nutrients that have Manganese in them are: Manganese chelate, Manganese carbonate, Manganese chloride, Manganese dioxide, Manganese oxide, Manganese sulfate, which are all fast absorption. Garden Manure, Greenssand are both good sources of manganese and are medium/ slow absorption.

Now if you added to much chemical nutrients and or organics,( which is hard to burn your plants when using organics) You need to Flush the soil with plain water. You need to use 2 times as much water as the size of the pot, for example: If you have a 5 gallon pot and need to flush it, you need to use 10 gallons of water to rinse out the soil good enough to get rid of excessive nutrients.

@garrigan62 @Astrocreep, can you recommend. Specific product or is there Manganese in ff trio formula, I’m having same issue but I am in soil… Thx for any help

@Astrocreep @garrigan62… Never mind you did name products , not awake yet

Any flower food should contain it

Not that I don’t trust you friend, but I think it would be still worth exploring if it’s a pH issue, yourself. Damage like this, from my own experience is due to the plant drinking too much without refilling 5gal bucket often enough, and pH drop.

Keep in mind, the damage is permanent, so you’ll have to focus on the new grow it see if it worsens.

Too bad if the damage is really permanent.

Permanent to those specific leaves. The plant can recover by replacing the damaged growth with new growth.
