New Start. NL5 X MKush, Hashberry, and White Widow

I just moved into a new place and have some room to start growing again--legally

Had a bit or trouble with my water before I installed an RO system. Also had a faulty pH meter that resulted in some issues for me early on.

Luckily everything basically recovered.

Now I think I'm just dealing with some nutrient burn? The ones that I'm having issues with should stand out.

Though not 100% sure its nute burn... any thoughts?

Nobody will be able to help you fully without close up pictures of the affected areas you're concerned about.

Looks like you could feed some cal mag or foliar spray. I think I see curling of the leaf tips. If I'm seeing right, that is a sign or nitrogen toxicity.
Take some closer pics and I'll try and help you if I can

Thanks man.

I'll post some new pics later on today.

I'm thinking of mixing a talespoon/gal of epsom salt and adding a few cups to each later. I read somewhere that leaves cupping upward means they need mag...I had been adding in Cal/mag to my RO water so thought I was covered...

The "claw" look of the leaf tips is classic nitrogen toxicity. If you can confirm that by using a guide, i would then use plain water until the nutrients level out

Thanks man. I got a few doing that.

Tried to take some more pics of whats going on with the leaves...let me know if you need something else.

and some more pics. Took a few of each plant.

Hey buddy i think your plants are deficient of potassium. They have more than just this problem but flushing properly and getting nutrients they can use will help you

Potassium isn't absorbed properly when there is too much calcium or nitrogen in your plants system. Check the ph of your water and flush with quarter or half of normal nutrients

Thanks Bud Big. What else seems to be bugging them in your opinion?


I'm running soil and have been been using 6.5-6.8, after adding nutes to the water.

This batch had a rough start...germinated in 2inch rockwool cubes under a cloning dome...HUGE stretch right out the gate. Then when I transplanted to solo cups the rockwool was too big and the plants ended up half hydro half soil...top that off with a broken soil pH meter...it was a rough two weeks...had to use the equipment I had lying around though:/

I'm still trying to pull them back around. So flush them all or just the ones that are showing nutrient problems?

I have been feeding with...Dutch Master Gold A&B, Calimagic, Armor SI, and a bit of Hormex.

Also, any idea how delayed the K deficiency is to show in soil?

I found this link helpful in diagnosing and treating plant deficiencies and any other issues that arise. Rollitup has amazing info and you can post to the marijuana plant problems area if you're really in need of help.

The idea of flushing is to get rid of the built up salts and excess nutrients that are causing the imbalance or inability to use those nutrients. You want to then replace what was there with a diluted solution so the plant can start correcting itself with the things it needs.

Thanks. Read through the link. Like the way its laid out.

Looking like Nitrogen toxicity, potassium deficiency, and copper deficiency at least...so something beyond nutrient problems is going on.

I'm going to go start flushing all of them now.

I'll let you know how it goes.

Good luck man, I'll stick around to see how things go

So things seems to be turning around.

Figured out that my RO system may have developed some algae in it, probably from me not purging the system after I replaced a filter. Not sure if this was the cause...but...figured out my well water comes out around 5.9-6.2pH. I'm use to city water and have never had to test pH on tap water before. Now I always will.

So this probably effected the soil pH a bit when i watered with straight water after feedings.

I have also dialed back my nutrient feeding, I'm giving everyone half of what I was and supplementing Armor SI with Diatomasous Earth and cal/mag with some epsom salts.

Also did some reading and found out that the soilless medium im growing in prefers a pH around 6-6.3, so changed my watering pH to 6.4-6.6pH so I give it room to drop once reactions start taking place.

I'm not 100% convinced they are out of the woods yet, on a few still got some funky one sided growth and coloring on the leaves, leaves twisting in a spiral, and some discoloration.

Will post pics early next week.
