Problem, or mutation.

I have a plant, that is two weeks old, a blackberry auto, I've grown a few of these and this one is growing normally in every way except that it's bright yellow with some faint mottled green. The development stem thickness petiole number, everything checks out as super healthy and exactly on time. At thirteen days it's just pushing up it's fourth node. The leaves have this faint patterning all over them and it's the same on the old leaves as the very newest.

What I don't understand is that if there's a genetic problem that's causing chlorophyll to not be produced, then how is that not stopping it photosynthesising.

Therefore it looks to me like a genetic mutation and how is it still working.

This is a normal blackberry auto a day older.

Deficiencies are not genetic mutations. Roots are more interesting in DWC to troubleshoot than the canopy, especially starting out.

You provide no proper data so there's nothing to work with or troubleshoot. We need to know what you feed them and at what strength (EC) and what's pH of the nutrient solution?

What kind of water do you use? Tap water or RO and what's the "background EC" of your tap/well water?

Why two plants in the same container?

Short answer: Why not? You get same or more yield with more variety (if you use different beans) so it's a win/win.

Because I top my plants, it gives me the option to top both or either at the 2nd or 3rd node or 4th node. In this case one was topped at 2 and the other 3 so one had 4 sets of branches and the other 3 sets. However it's unusual for me to use the same beans, so normally in addition to the options above I get more variety without losing yield.

In my 3 in a pot grow, I topped all the plants at the 2nd node as it would obviously be too chaotic otherwise. Didn't increase the yield only got 12 zips in total, 6 off one and 3 each off the other two. But I get 3 difference strains to enjoy. I have to maximise my space. ATM in growing in an en suite wardrobe off my room. You can see how they turned out here

However I'm constantly experimenting with what works for me.

However right now I'm probably going to leave this crazy yellow Blackberry to grow out without topping, but I'm wondering if what ever is causing her to be yellow will not also produce bad flowers results.

I should have explained, this plant did not go bright yellow, it was bright yellow from the first true leaves, only the cotyledon leaves went green. When it became apparent that wasn't going to change, I thought the only possible explanation was that somehow I had used on of the parts of the nutrient twice and missed out another. This is almost impossible but I changed the solution anyway that it didn't make any difference.

I used a 16L pot filled with expanded clay, drains out the bottom into another shallow pool with some air space for the roots that come out the bottom to expand into and that drains into a tub that top feeds. Pretty simple stuff, nothing really to go wrong.

The reason that I figure it's a genetic mutation is that it is growing in exactly the same way and at the same fast rate and any other Blackberry I've grown. It's been sitting in about 700ppm the past 10 days. The whole point of my set up is focused on health roots. Hence SWC instead of DWC

If this plant was growing weakly, I'd just terminate it. But it's looking too vigorous to do that.

pinch of epsom always greens them up for me. Too strong of feed burning roots

If you can make it work then go for it. That grow looked good.

This is untrue. A room full of clones/stable seed genetics will win on yield every time because the canopy will be even unlike with different strains or even the same strain with varying phenos types

The wavy leaves and interveinal chlorosis suggest Cal/Mag deficiency.

I only grow autos, due to the convenience of no dark cycle. So that doesn't apply to my situation, which is what I was referring to. Everyone has different priorities mine are just to make everything as simple as possible, but no simpler.

Anyway back to the thread topic, if this were some sort of deficiency, then it must manifest itself somehow in sub par growth, but at two weeks this girl is growing powerfully and normally, at what point can we conclude that yep, it's not growing conditions. What i'm getting at is the obvious lack of chlorophyll pigment does not seem to be making any difference. I mean if it were not photosynthesising due to lack of chlorophyll then it's growth would be stunted, Yes? No?

Why not have 2 plants in 1 pot. They fight for root space, one ends up a runt while the other ends up big.

That was the reason I did my first three in a pot grow, because I simply don't believe that is true for hydro due to they ain't fightin over nothin', if there's more than enough root structure on each plant to get as much nutrient as it can handle. The only limitation for me is that it can get a bit crowded, but I got 12 zips and that is without a scrog because it was too much work, I put a scrog in then I cut it off so I could just pull them apart. In the photos, the plants are all so huge that I cannot see all three at once. You can see the whole grow in this thread. It may certainly be true in some circumstances, but it doesn't have to be. So there it is proved.
