Nutrients for soil grows

I was reading on a grow journal and a fella had topped and transplanted and it was stunted it grew small buds and took forever to recover...So I would do what sinQ said experiment top and prune one and let the other grow wild ... I am not gonna prune or top mine I want it to do what it does naturally. I have pruned photoperiods and they didn't do so well so I don't think an auto will take to it to well. But it is your grow so just try it out c what happens I would think genetics and full life span would have something to do with how it reacts and performs
As a new grower I will start with LST and after I have a few grows under my belt I will start experimenting with some of the other techniques. First I have to get a stock of buds up so I have something to smoke. I made a promise to myself to either grow my own or stop smoking I am done with spending $ on buying weed. It will be another month before I can start my first grow as I currently live in Thailand but will be relocating back to Oz next month ( I dont wish to spend any time in a Thai prision for the sake of a bit of smoke .. lol )

What is oz

Around here it might become "ounce" as well. :0)

I've got myself an Oz of Billabong from Oz....I'm off to Oz!
Oz and oz are different, I think spelling and context make all the difference. But don't quote me on that what would I know as I speak Australian, most people will tell you that is not even close to english ;)

Would just give it a magnesium supplement, but the only thing I could find at the local was cal mag so went with that. Will try to source the magnesium on its own once the cal mag gets used up.
Have you tried epsom salts (magnesium sulfate) for your plant's magnesium needs?

I think you only need a partial teaspoon in your entire container, but I'm not sure. I use SubCool's Super Soil recipe. It calls for a few tablespoons of epsom salts (specifically for mag needs), but that would be for an entire cubic yard of Super Soil. You can Google the recipe, but I'm fairly sure it's listed in Rollitup too.

I like Super Soil since all you need to do is water (pH checked of course) from after seedling stage to harvest. No added nutes, amendments, or expensive Hydro store bottles of god knows what. Just water.

I think it's a 1/4 tsp per gallon....
 
Every grow I did before the calmag presented with purple stems and purple veins etc which the Cal Mag seems to remedy. I put it in at 4 weeks as a preventative rather than a treatment from past experience, and keeps it green.
I occurs to me that this may be a nutrient/mag lock-out situation. Very often lock-out is due to the water not being in the 6.0 to 7.0 pH sweet spot. You mentioned your water is pH neutral, basically 7.0, and that your are pH adjusting. But I wonder if the pH is checked every time just prior to watering. Or perhaps checking before adding amendments to the water. A lot of growers check the water before adding fertilizers or whatever, even organic additives, and this does change the pH of course. Not saying your doing anything wrong here, just thinking of potential remedies.

You don't have to worry about the PH of your water unless it's way off. That's one of the advantages of organic soil -- it buffers PH for you.

You grow soil, you don't make it. I have black soil my neighbour has red clay, literally 1 foot from my wall the clay starts. We've been working charcoal in for almost 40 years.

I bought one Pineapple Express clone. I used a mixture of Kellog's Patio Plus and Fox Farms Happy Frog and some perlite mixed in.
It's growing pretty well under 1000w LED. One thing I'll remember for future grows is...I started adding Alaska Fish oil 5-1-1 after the first 3 weeks at HALF strength. The leaves grew healthy but are darker green than I'd like. I figured out on my own that there was still plenty of Nitrogen in the soil, even an excess. Adding in the half strength Alaska 5-1-1 caused nitrogen overload. I've since ceased adding any Nitrogen for the time being and instead add FF's Big Bloom which has little to no nitrogen in it. Gradually, the top growth leaves are starting to lighten up in color. With today's rich soil products containing lots of nitrogen components, I now understand why some growers flush their new soil before planting. Some say that all the nitrogen is gone after 3 weeks and more must be added. Not necessarily so (with today's nitrogen rich soils).

Happy Frog is weak soil.
I bet something else is going on.
Dark leaves can also be a sign of mag deficiency. Are your leaf stems purple? I bet your fish fertilizer provides plenty of calcium but insufficient mag.

I've just started adding Cal-Mag due to using RO water (4 week old plant -oops!) and for leaves with white tips (I read Mag deficiency caused that) . I've not read of dark leaves due to a mag deficiency but the Cal-Mag should improve the color of the leaves if that's the case. The dark leaves happened way before the white tips. Some stems ARE purple, yes. I'm hoping the micro nutrients helps all three (dark healthy leaves, white tips, some purple stems). I'll be sure not to neglect the nitrogen either. Thanks.
P.S. I'm thinking of adding in some gassed out city tap water to the RO water for the micro nutrients contained in city tap water (corrected PH of course). That may not be necessary, tho, if I add the correct micro nutes to the RO water. I hope it doesn't get me having to mist spray micro nutrients onto the leaves (foliar?) to correct future micro nutrient concerns. :)

The symptoms you describe are sounding like general base nutrients are needed. Too much nitrogen will start to lock out nutes also. Well too much of anything causes conflicts.

The dark green leaves if low can be potassium. Especially if the leaves are dark and thickening and droopy at the tips. Also the white tips have relation to magnesium and potassium.

The purpling is probably phosphorous. I would add a balanced general complete Grow nute with a good amount of runoff to basically re-set the medium. Maybe a 25% or a third strength to start.
