Yellow Scabbing?

Hello - avid learner, here. So my plants were super healthy until it seems I may have overwatered but clearly showing signs of something else going on. Just using fox farms happy frog, PH balance 6.5, RO Water w/Liquid seaweed and some molasses. The yellow scabbing is what I'm concerned about. Thoughts? solutions?

Online seems to point toward "calcium deficiencies" but I had thought for seedlings potting soil would be good enough.

Those washed off now, I think it's the molasses in the water drying up. So if I were to remedy this potential calcium deficiency with Dolomite Lime or what not, whats the best way to add it since Its already potted? Add it to my watering?
 
Don’t change your pH, like someone recommended, just keep using 6.5 for soil. I’d be more concerned about the white in the leaves and would make sure it’s not a fungus or powdery mildew. If you aren’t foliar feeding then there should be no white residue on the leaves.

You do realize that a water pHd to 6.0 is 10x more acidic than 7.0, right?

“”If you grow in soil, the optimal pH level for the root zone is between 6.0 and 7.0. However, there is no set number within this range that is “best”. Instead, it can be good to allow for some natural fluctuation within this window to support optimal nutrient uptake. So as you adjust, try a slightly different reading each time”
 
Actually there have been great strides in PH availability charts to further stray from the guessing game. This is from Grand Master Level, a grower I'm sure most know. This chart shows that a fluctuation between 6.7 and 6.4 is ideal as certain micronutrients are not passed through at higher levels even within the traditional 6.0 to 7.0 PH range.

I believe what @ProteinPapi420 was talking about was going up and down a couple of points on the scale periodically just to ensure maximization of nutrient uptake, not changing it randomly.

Hard to tell sometimes what's meant, but in this case, I think I'm understanding correctly that he's suggesting that minor ups/downs can be beneficial, to which I do agree. Ignoring, or blatant irregular swings is of course detrimental, but the periodic 0.1-0.3 movements plus/minus your target will help ensure all nutrients get uptaken (granted that it is a very small swing, and not wildly variable).

That's a single chart showing potential uptake. There are far more variables involved in just relying on a single chart. For example, chelated nutrients are designed to allow the nutrient to be uptaken outside of the range depicted in that chart, and unless you're organic, you're likely using chelated nutrients.

Besides, anyone who classifies themselves as a "master grower" goes out the window immediately.

He's a fully organic/living soil grower and the name is less about him, but what he and a his group of associates aspire to be. Grand Master Level. If you listen to any of his material this is obvious.

A natural fluctuation is a fluctuation of a few tenths, not a whole number.

Just because you can quote from some web page doesn't give you the right to chastise a standing member of this site who's proven himself with quality advice and equally valuable questions. I can copy and paste things I find randomly that makes sense in the context too.

Depending on the actual nutrients in use, sliding up and down a couple of points (ie. 0.1-0.3) can provide uptake benefit, but it's necessary only in certain cases. Also, the person you're bouncing off of here stated a suggested target pH, which anyone who knows anything would agree with. 6.5 target pH for soil, period.

They recommended switching it up between 6.0 to 7.0 which is a huge range. I may be being a little harsh with this person but they are making mistakes in their own first grow and they are just repeating shit they’ve read without even understanding what they are saying. And they aren’t letting the OPs know they have no experience with the “advice” they are giving.
 
Then there’s this...

And a day after they said they top their plants 4-5 times, they somehow managed to screw up topping their plants for the first time.

Lol you seem like a person who loves getting into fight online. First of all yea this is my first own grow but I’ve watched my dad for 10 years growing pot so I definitely not new to this. I asked the question about lst and topping at the same time cause we never done it. We either did lst or topping but not at once. And What I meant to say “topping isnt stressfull for your plants” What I meant with this that prople are really afraid of topping because they think that they can’t recover and what I meant is that its not that stressfull toa killa a plant if you do it right. My other question was will it reciver cause I messed up the topping, but I learned that I should start train them when someone is high af not that Im not on anything I see where I messed up. Also sometimes what I say is sound some what different cause my english is not 100% since its not my offical language or whatev you calk it. Maybe I have to read it a couple times before I post it!

No, I would rather not start fights. I just don’t like seeing someone with no experience give out incorrect advice. Watching your dad grow for 10 years doesn’t mean anything. Most of the advice you’ve been giving has been incorrect. If it wasn’t, I wouldn’t have given you a hard time. The only reason I blasted you in that post is because you just keep giving bad advice and you don’t have the common courtesy to tell the person you are responding to that you are currently in your first grow.
