Do I have a problem

[BTzGrow]

I've got a indoor grow with a single plant. Using soil FoxFarm Mother Earth(new product for them, given to me as a sample). My water is 6.7pH. Recently potted from a 6" square plastic when the roots started poking out the holes, to a 5 gal Root Pouch. Typical Temp when the light is on is low 70's, lights off mid to low 60's. Typical Humidity 50% but higher around 70% or slightly more after watering. Just switched over to a Perfect Sun Mini LED(see my thread on that), still in the first 7 day adjustment period after being under a T5 22 Sun Blaze Fixture. Current light height is 30inches to allow the plant to adjust to new light spectrum. I have had this problem previously after re-potting and or using worm tea in very light 50/50 dilution mix.

regrets on the turned photo here, will try not to do that again.

So here are three pictures of fan/sugar leaves with slight browning tips. Any and all suggestions would be really appreciated. Previously when this happened much earlier in the grow I just removed the leaves and they were down at the 1st and 2nd nodes.

Looks like nute burn. Prob from the worm tea.

I had a feeling about that, should I cut those leafs off, leave or ??? Given the leaves that it's affecting I'm guessing that's not the end of the world, just feel I should not add any worm tea for a week or two and see how things progress. Thanks.

If it were mine I'd cut them. If it gets worse you might have to flush.

My problem seemed to calm down for a short while after I started this thread and seems to have come back. I haven't used any of the Worm Tea in 2 more than 2 weeks, so I'm doubting that is the problem. Symptoms appear to be a CalMag deficiency so I have mixed about 1/2 teaspoon of Epsom Salt with a quart of water to start with. Spraying foliage twice a day and added about 250ml of mix to soil.

Regarding a flush, as I have not added any Nute's at all at this point other that what was included in my original soil, I'm not sure what I would be flushing out that would be bad, and perhaps robbing the soil of it's original mix. I'm using a soil called Mother Earth GroundSwell performance soil.

Which seems very similar to FoxFarms in many ways. 1.5 cuft bag was given to me by my local SDHydro shop.

It has also been suggested that I might have an issue with potassium and that I should put in some 0-10-10 bloom nute. I want to be very careful adding nutes of not needed. That would require a flush. Gets into a vicious circle jerk at that point.
