Start of a deficiency

[Theterpinator]

Hi Guys,

I am hoping some will be round to give me some advise soon.

I got up this morning and noticed the brown pattering beginning on the blue Kush plants.

1.5mll sensi a/b 1.5mll cal mag, 0.066 mammoth P, 0.5mll silicate (first and last dose) 1ml/10l drip clean. I turned the autopots on yesterday with the this feed strength. It would great to get get this locked down asap. Any advice greatly appreciated [emoji846]

I haven't worked with autopots but they look a little underfed and that's a magnesium deficiency. I'm new and someone more familiar with your setup may chime in differently.

When I turned on my Autopots, after the trays were filled I did one last top feed with 1-1.5L to make sure the coco was saturated. Everything has been going good since then.

Hi guys,

Yes I did exactly that, each plant got 1.25l of almost the same chemicals as I listed above there. I top fed them on the 1/3, the new led also makes them look more yellow.

The new growth at the top of the plant does seem to be fine.

Thanks for the input. Hopefully @Waira or @pop22 will walk in shortly[emoji113]

The spots, unless they get worse, are likely cause by a ph shift, and are not cause for concern, I see this now and then, usually on just a couple leaves. I agree they look underfed, their color look a little too light green to me.

Thanks for dropping by @pop22 I have just taken a couple of more pics whilst the light is off.

They do not seem to be getting any worse.

I think the mix of the skyline and my camera make them look more yellow than they really are?

 

[pop22]

ahh yes, thats better. I'd say your good, but keep a watch for a day or two

... nice call guys! I'm with @pop22 , looks like a pH hiccup... coco can be a bit squirrely sometimes! .... I see very similar well defined necrosis like this in Hydro as well,...
