New Grower My First Grow. Finally. Feedback appreciated!

Yeah when adding any nutes. The ffof is gonna be hot unfortunately

Yeah, I’ll never use it again. So my nute plan is to use Jack’s 321, but the first part has nitrogen, so maybe I’ll just start by adding calcium and magnesium in the next watering and go from there.

Me either but its because its expensive for 13gallons of soil, i think its good soil that will last 4-5 weeks but it is hot and certain strains don't like it the 1st few weeks. It will always have a special place in my heart but time to move on to cheaper better things :smoking:

Might want to check on how much cal/mag OF has in it already before adding more.

I think I pretty clearly have a magnesium deficiency though?

@Mañ'O'Green can probably chime in on the locking out of mg due to N tox

Alright, I mostly try to not ask for help, but now I’ve gotta. Paging @Mañ'O'Green if you don’t mind, sir.

I had been thinking I’d been seeing nitrogen toxicity and magnesium deficiency. Some pics a bit earlier in the thread. Had to leave town for a couple of nights on Thursday, and it was watering day. Still just went with water with a bit of Fishshit, because I was second guessing whether it was time to add nutes. The big girl looked like this:

Two and a half days later, amid steady 77 degree 60% rh conditions, she looks like this:

And one of the little ones has this going on:

I expect the other little one will follow.

the big one needs water and the little ones will tomorrow morning. I currently have on hand:

Jack’s 5-12-26
Calcium nitrate
Magnesium sulfate

In other words, Jack’s 3-2-1.

I’ll start with the big one. I think she has a bad calcium deficiency, and I believe she probably has a magnesium deficiency too. She also stretched a number of inches in these last two days, especially her main stem.

I think the little one is showing a calcium deficiency.

I offer these possible diagnosis because I want to show that I’m trying to figure it out, but mostly, I’m hoping for help.

Should I water the big girl with the full Jack’s 3-2-1 approach Now, five hours before the lights go off for four hours? Or just stick to calcium and magnesium? Should I use the full recommended dose for their first feeding, since their deficiency/deficiencies are clear and advancing? Should I remove all damaged leaves? Any other advice?

As for the little one, should I water her with some calcium nitrate tomorrow?

Any advice is more than welcomed. Thanks!

The big one is showing symptoms I believe is from way too much cal-mag and the second one is just starting to show too much cal-mag. You are locking out the potassium.

You need to learn about and understand how to fertilize in Balance.

But I haven’t fertilized at ALL. I’m still just in the original OF/Light Warrior 80/20 mix. Always watering around 6.4 PH, give or take a couple of decimals. Could the “too hot” OF be wreaking this kind of cal/mag havoc 30 days after sprout?

What is the source and starting PPM of your water?

Yes, we have seen big quality control problems with OF. It is in the infirmary continually. Are you saying you did not add the Cal-mag like you said you were?

I have no way to actually know what you have in the pot. If it is a case of way too much Dolomite Lime in the OF you could try adding some of the Jack's Part A without the part B but this is a gamble because we are flying blind. Flushing does not work in OF.

The damage you see in the leaves now was done days or weeks ago. It will never go away. You just want to stop the spread.

Unfortunately this pot has been out of balance for a while and I have no way of knowing the cause if you have added nothing. Unless your water is very high PPM?

Sure appreciate your time.

Correct, I didn’t add cal/mag. I was considering adding calcium and magnesium to her next watering, which would have been today/tomorrow. But the big girl looks rough so I came here for help as I wasn’t confident in my diagnosis.

The only things I’ve ever added to her water are Fishsh!t and a little yucca powder. Nothing else. I water using local spring water that has a PH of 6.8 and PPM of 35-50, compared to 8.2 and 125 in my tap water, so I thought it was a good decision. I PH the spring water down just a bit, between 6.4 and 6.7 or so. I did water them once at 6.8.

This plant is a Seedsman freebie, so I thing the genetics are a complete gamble.

I’ve been hesitant to blame my soil, because I know I’m a newb and therefore prone to mistakes. But I feel I’ve been careful with my environment and water, so I’m not really sure what else I could have done, or where I went wrong if I did.

Thanks again for your time.
