Reave's Soilless: Peat, Bark, Sphagnum, Perlite, White Widow 2018

Well the larger plants are doing well. Some of the seedlings are not to happy.

That looks like magnesium already! Are you giving this greedy little thing some calmag?

Yes I am. Does it take a while to correct? I fed them on Thursday. Im not sure if it has progressed or stayed the same. I am also wondering if the calcium in my water is messing with the ability to absorb the magnesium.

They also are not as green as they were. The last feed was with cal mag and water at 6.0 ph.
 
That looks like a calcium deficiency to me. If you think your feeding enough, let it ride out. The old leaves won’t be fixed but you will not see new spots on new growth (if it’s fixed)

Could be ph locking out the calcium as well, which If that we’re mine, I would check run off to find that info out:)
 
Chart shows calcium uptake at 6.0 and up in soiless medium. The slurry test showed the soil was 6.7ph. So I'm confused how I would be having a calcium or a mag deficiency when I have been adding cal mag. Could it be phosphorus?

Had a chance to get a better pic of the worst one. She was in the back.

I am not convinced that you are running at the right pH for that mix yet, and have been waiting to see results. as an experiment, why dont you try moving your pH around a bit... try once at 5.8... try another at 6.5... See what happens. Calcium is included in your calmag products... if one locked the other out, would they do that? Calcium also is non mobile, so its deficiencies show up in the new growth. Magnesium is semi mobile, and it can pop up anywhere.
I would try giving the problem plants a bit more dosage of calmag. The rusted areas will never go away, but if you can stop the progression of this symptom, you have finally given enough. Some plants, especially WW, are very hungry little girls. WW is not exactly a beginners level difficulty plant... she has needs in excess to many other plants you will grow.

Hmm. Just my luck I guess pick a hard medium and a hard plant for my first grow. I guess I just wonder why the larger white widow one is doing well. I have been feeding her at 5.5 this whole time.

I'm not planning on keeping all these plants anyway so I like your experiment idea. I should still wait for them to need water correct?

Always... but you may have just solved your own mystery. I would try watering and feeding at 5.5 and see if the others start doing as well as the one already being given this treatment. If you are giving partial feeding, stop doing that and give the full dosage... this is WW. When you see her start to frost up, you will understand... she needs a lot of nutrients.. and will happily take whatever you give her.... within reason that is. :cool:

Ok in the mean time is it ok to foliar feed some cal mag with my seaweed?

I can see no harm in doing that, and doing it often. Take advantage of veg when you can get away with this without water trapping in the flowers and causing problems.
 
Reave said:
Ok thanks. Last question for now. I read that it's better to foliar feed at lights out. Is this correct?

it is... the pores open up wide at lights out
 
One of the reasons I was asking about phosphorus deficiency was because that would make more sense since it needs about 5.5 to 6 in soiless according to the chart. If the soils slurry test revealed that the soils ph is 6.7 when we water at 5.5 as it drys the ph should drift towards 6.7. When I watered at 6.0 - 6.1 it wouldn't take to long to drift out of range.

I realize this is a debated topic but starting at the bottom of the range and allowing it to drift up makes logical sense to me.

Another thing I am curious about is why the ph range that nutrients can get absorbed is different for hydro and soil. I googled all over and I couldn't find a satisfying answer. Guess I should take a botany course.

I'm more interested by the day.

:D:D
 
sorry, but there is no way the pH of your mix has anything to do with anything... it is not soil. It is a soilless medium. When you water at 5.5, it is the nutes breaking down and the solids in the water that raises the pH.... your mixture of peat, moss, bark and perlite is not causing much of a drift.

But the ph does move up as it dries ?
 
when you did a slurry test of things in your mix which is comprised of a bunch of solids that can not go into solution as broken down soil can do, all you really did is test the pH of the distilled water minus a little bit of broken down peat that pulled down your reading a little bit from neutral. Soil contains minerals and elements in their basic forms, but your mix really doesn't have a pH... it is chunks of mostly inert material.
This is not soil. The same rules do not apply. This is hydro.
In hydro, the only thing that drifts is the pH of the solution as the plant uses up the acidic nutes and you drift toward the pH of the neutral water.

Thank you for the clarification.

Trying different pH with different sprouts is a great idea.

If you're not planning on keeping these I would put your next seeds in a medium we're all familiar with so you won't have to start off flying blind.

I found a place to get pro mix as winter ends I will have access to all the green house goodies too. Sucked having to start in something odd but gives me the chance to learn hands on.
