Ca deficiency from low pH?

[FullDuplex]

Hey @Waira , I've received my ph up, calmag, and I also included tiger bloom in the order. The pot is fairly light and the surface soil is slightly damp, not quite dry all the way. I also havent gotten a replacement yet for veg nutes.

Additionally to what I said above, what recommended course of action should I take?
I was thinking a pH corrected watering with just calmag to start. Maybe just a small feed and not to runoff to see how she reacts. But if it's a nute deficiency then maybe I should feed as well. Though on this front people usually say less is more.

Any thoughts?

Thanks

Also FYI, I've attached a pic of the full analysis of the nutes I used (only one feed done up til now)

One thing that i would do is wait until that pot is dry, she is over watered here mate. You need to let that root zone breathe, that second water to "fix" her did her some damage. The best thing that you can do now is allow her to recover and to do so you need to let that root zone dry out. if the top of the soil is damp no need to water, ill wait until my fans are blowing the soil on the top and at least a knuckle and a half deep before i water.

Another thing that you should have in the tool belt is a soil moisture meter, they are a godsend if you are growing in some sort of soil mix. Take it easy on the water and get some proper airflow in there too.

Thanks @FullDuplex , I hope it's recoverable at this point.
I'll look into getting a soil moisture meter. I do have a fan on at plant height all the time and rotate the pot a few times a day. Was contemplating installing a second inflow fan though.

Im a bit at a loss though and don't know what to think. The pot seems very light. The soil up to my first knuckle is bone dry, up to my second knuckle it is getting cool and a touch moist, but my finger isn't wet to the touch from it.
It's drooping a bit worse now and the lower leaves are starting to blotch, as well as some of the tips are getting yellow and crisp.



Things are kind of spiralling downwards

Looks overwatered to me, for sure. The way the leaves are swollen is a good sign. If you have an extra pot and soil, I suggest filling it and gauging dry weight from that. What can seem light is sometimes not so much. Lucky for you, you have experts here to guide you. Do yourself a favor. Don't do anything until they get back to you. One of the worst things to do is keep trying different things. It will only make matters worse. You'll be fine. Be patient.

Peace

Thanks @Yeatster

I guess that's one lesson learned from the last watering trying to "fix" it.

Guess I'll have to buy another smart pot online. Sucks being in a small town where nothing is available. Good thing for Amazon Prime!

I wouldn't go buy another smart pot on my comment. If you had o e, great. Wait for Waits buddy. You're in good hands

No worries, it's a good idea for comparison.

Checked this morning after another night of drying. It continues to droop and curl. And the weight of the pot hasn't changed much.

Since it was overwatered and roots needs oxygen, at what point do I let the plant get to before giving a watering again?

This is the exact reason why I said, dont do anything, based on my comment. Sadly, my last post was incoherent, due to self toxification. Waira is the man.

Thanks @Waira, no worries. it definitely is a sensitive balancing act of all these different factors. You are likely right on all accounts. I won't use that fertilizer anymore and will get something else for my next grow.

I did end up watering it though, It was lookin pretty sad and pot was extremely light. I did it with a mix of Cal mag, fertilizer, tiger bloom, and pH up. I did a very minor amount of the fertilizer and a half dose of the tiger bloom. In the rush though I forgot to test runoff, though my strips aren't accurate enough and doesn't seem to work right past 6 pH. I've attached a picture of what the plant looked like a day after feeding, definitely better.

I have a moisture/pH probe, and a digital pH meter on order, but on this last watering with just calmag and pH up the runoff was showing close to 5 pH. So I'm definitely on the acidic side. Hopefully all my gear is here before next watering so I can get this soil pH corrected. Any helpful tips?

... that dry huh? -- that really screws with things, so avoid that again at all costs! ... keep the water inputs at 7.0 or a bit above,... feed lightly now,as the fert's will lower pH, and the roots are feeling worked over some,...
