A conundrum

[JDU]

So I'm growing in soil using phed tap water. There should be no nutritional deficiencies yet 1 plant out of 22 looks like this (Magnesium?). She's growing just as fast & otherwise healthy looking as the rest. You can see from the droop that it's time to water so what should I do for her?

[Mr.furley]

It looks like bugs, what are all the white spots? When I zoom in

[JDU]

That's Himalayan sea salt. I dont have a mister- just a spray bottle.

[Mr.furley]

I always go to ph first then double check the plant to light proximity when it a At the top of the plant problem. if its a deficiency it is a immobile nutrient problem and to me looks more like a zinc deficiency. Calcium and magnesium have symbiotic relationship and you'll usually see signs of both.

[JDU]

Thanks. Zinc huh? What can I do about that? & why aren't any other plants affected?

[Mr.furley]

Some Phenos are a heavy feeders, some phenotype just suck. Are they all the same Plant? Seeds? Phenotype? Age?
Liquid micro nutrients with trace elements is the easiest way.

[JDU]

Seeds. Planted them Oct 3rd.

[JDU]

I'm thinking PH too. I wonder if I should take her to the shower & run 20-25gal water through the pot. That would probably deplete the soil & I'll have to add nutes for the rest of the grow.

[Mr.furley]

That's the conundrum.
A good flush will fix alot of things but will finish off your soil. What has your pH checking/doing look like?

[Mr.furley]

Same bag of soil? What kind?

[JDU]

I water at about 6.5 with a slight flux.
Oh shit...... I feel pretty smart right about now.... Yes I remember now that I WAS a little short & mixed in some used soil to finish transplanting..... I bet I found that used pocket.... Thank you once again Mr.furley I guess I'll get some nutes ordered & see how she does.

[Mr.furley]

You can top dress with some new soil

[JDU]

That was my 2nd thought too but what I have I've composted & it hasn't decomposed yet & the bags at the store have been outside all winter & are 25% mold. They will call me when new Spring stock comes in.

[JDU]

I know it'll be ok to fertilize her only- this is dif from last time cause her dirt really does need some help. It's just nerve wracking lol.
