What is this?

75F
50%RH

21 days from seed.
5.8pH drifts up to 6.0 over 48 hours back down to 5.8. Meter is calibrated and in working order.
400ppm (500 scale) .8 EC.

Was previously at .5EC, but upped it when I took them out of my aerocloner.


These other two are a different strain and are at 350ppm with same pH swings.

Personally I go 5.2-5.8 in veg and 5.5-6.2 in flower, to me it looks like magnesium problems, if u set the pH at 5.2 and let it fluxuate up the plants get full access to all the required nutrient's uptake pH values

Also .8 is far too high for that stage for some strains but hungry ones like ch3ese can be punished with a high ec, my red cherry Berry's 3 x your size and only just moved to .8

Yeah i think I should of kept em at .5 EC which is what they were on.

I kept two that werent showing issues(not pictured) at the .7 EC and they still seem fine.

The other three I dropped to .5EC. One still looks bad.

Looking at pic 2 of 4-----have you checked closely for spider mites?

A~~~

You definitely have a nute burn flush them with plain water for 48 hours then adjust the ec to 0.5 and ph at 5.5 this should sort the rest out but the damage is already done on those few leaves they will probably fall off in a week or so

Looks like phos def. Prolly from nute lockout from moving to .8 ec to soon

I'll keep an eye on it.

Yeah I know the damaged leaves won't repair.

I have them set at 250ppm since Friday (tap is 70ppm).

I haven't. I can look. Plants are tiny so i'd be able to tell easily enough. Never had a pest problem before. Nothings changed really.

Let me just clarify something. So these plants just came out of your aerocloner and into the Hydroton pellets, right? How long ago did you transplant them? Was it just a few days ago? The only reason I'm asking is transplant shock is pretty common when you go from aero to pellets or soil. Sometimes it's not too bad but sometimes it can be hell. The only reason I say this is because...

I'm living it right now. I kept some strains vegging for a really long time (mother plants). They were all doing great in my Aero veg unit. I put them in some 10gal soil containers and two of them did great but one of the plants took the move hard. Wilting leaves, dead spots and overall unhappiness. I just talk to her softly and say, "you're gonna be alright little girl, just hang in there" and then I wipe away the tears...from the plant silly boy, not me! So the plant is slowly coming back and I think it's going to be okay but I think her sisters are plotting against her so I'm not sure how the story will end...

They were just transferred to the bubble buckets like the day before the photos were taken.

This is them now at .5EC. Seems to be turning around. The last one didn't end up going bad, just looked like it.
