Looks more PH related in my opinion, although the rest of the plant is largely healthy- and it's hard to tell under the blurple light. Do you check your runoff PH? Input PH?

Why do I have rapidly spreading yellow on my leaves?I have this yellow spreading on some of the larger leaves and it's moving super fast. Please help. I've done research and it says it's a deficiency, mostly likely cal/mag. I added that and it got worse, now I'm thinking nutrient lockout? The pH is fine. What do?!2mo ago

I've been getting some of the burnt tips as a result of the watering with nutes. The nute mixture is already half the recommended dose. I've tested my runoff pH and its about 4 or 5 even though I've been pHing my water to be around 7 and no lower than 6. Anyone have any tips?Week 8

Leaves continue to get yellow and fall off. Plant dying, bud looks okay.Still having issues with my plant. Leaves are getting more and more yellow and 2 have fallen off. Pretty far from harvest still for the leaves to be getting this yellow. Temps in tent are 18-22 c with leds 200w act wattage. Overwatered once but I doubt it would cause this. Ideas?6y ago

Cal/mag problem or heat issue?A few leaves have some problem spots popping up here in week 6 (see pics). No nutes, PH’d water. FFOF/HF/Perlite mix for medium under 20 hours of light. I’m guessing either got too hot from being in 90F heat for an hour or needs cal/mag? Any advice from any veterans out there?5y ago

Yellowing continuesLeaf yellowing continues, is it normal as it’s already the end of the flowering for them ? Can this still be influenced? Previous advice was to raise ph and give N. Yellowing still goes, flushed them today, one yellowing plant was giving ec 1,7.Leaves. Color - Yellow

Yellowing leaves on bottom and middleI am growing in organic soil and transplanted 3.5 weeks ago from .75 gallon pot to 2.5 gallon pot. I noticed some yellowing on some of the leaves, generally towards the bottom but a little in the middle.
Is this a cause for concern or do some leaves natural die off?Leaves. Color - Yellow

Can't deal with yellowing leaves in 4th week of floweringBeen having this problem for a few weeks. I suppose its deficiency of Mag and for the last week or so I've been giving increased portion of CalMag (for 1.5l of distilled water TriPart grow 2.1, micro 2.1, bloom 3, Calmag 12ml). Should I give them more time or its something else?Leaves. Color - Yellow
