Con el amarillamiento de las inferiores, tambien podria ser falta de N. Revisa el PH que no sea que te bloquee alguno de ellos.

PH Fluctuations and/or Nutrient Issues?
I'm Running a Recirculating Deep Water Culture System( hydro). Had PH dropping dramatically a few days back but did a full water change and everything has stabilized. Just Flipped to a 12/12. Does it look like that was the issue or is it nutrient toxicity/deficiency. Or Stress?

Bottom leaves turning yellow, with brown spots. And the tips of the top leaves are yellow aswell.
De onderste bladeren van mijn plantje hadden in het begin witte vlekjes en nu zijn ze helemaal geel. De bladeren daar boven worden nu ook geel, en er komen bruine vlekjes op. En de puntjes van de bovenste bladeren zijn ook geel. Wat kan de oorzaak zijn?

Anybody got any idea with what's going on with these 2? The 2 larger plants are showing the signs of some stress on the fan leaves. Oddly enough the runt of the 3 is not showing these signs. Has anyone seen this before or can help me identify it?

Yellow leaves working out towards tips
Yellowing of lower leaves, from the stem working towards the tips. It’s been hot and they’ve been home alone for 5 days with just one water on the 3rd day. They had a small amount of bloom just before I left! During veg they were on fish mix, but not very much (1/2 dose).

Yellow Burned Bud Leaves. Purple Calyxes. Red Stigmas. Stunted?
As u go from top of canopy to bottom, the leaves get darker green and less burn. Lamp is at top of 3ft tent, 10 inch above canopy. Feed is at 1.3EC/6.1ph. Runoff EC climbs, then I FloraKleen flush about once a week. So is it just light burn? What you see? Is she stunted? Thx.

Calcium Def/Wilting or other issue?
So after 24 hours of feeding it CM Plus it doesn’t look any better. I’m hoping there is not another underlying issue. Environment remains the same. Pics are 24 hours apart. Or will it take a few days + before seeing improvements?
