Sieht wie beginnender Stickstoffmangel aus. Eine gute Gabe Stickstoff ist jetzt notwendig. Beobachte, ob die jüngeren Blätter auch langsam heller werden. Und falls möglich, gerne auch den pH-Wert checken, evtl. kommt das Problem daher.

Look like Zinc and Calcium deficiency? Watering with 5.8/5.9pH, 2.06 EC (Runoff 5.8pH, 0.78 EC) Few leaves had small nutrient burn on the tips earlier this week. Nutrient burn appears to have tapered off.

PLEASE HELP ME, my frozen black cherry is drying, what could I do?
It’s in the early third week of the flowering phase, but I don’t know some lower branches are drying out day by day, the first three photos shows what I mean, the last one is of the higher branches. Haven't watered for a day, but I don't think its a overwatering problem.

Nutrient burn?
Hello I have one plant with yellowing leaves that are also curling downward. Only one plant of 6 has this problem, I suspect maybe this one is just sensitive to the nutrient rich soil? I am using fox farm happy frog and have added no other fertilizer. What to do, flush all?

Strange yellow patches
This is a new one for me, sont think I've ever seen discolouration like this before. My first thought was having left some nute solution on her leaves after feeding but pretty sure I've ruled that out and more leaves have begun to show the same discoloring. Any advice appreciated

Leaves changing colour
What’s wrong with this plant? Put her in manure instead of soil, just read John innes and thought yeah that’s fine 😂 I’m thinking it’s holding water more than it should or else it’s a PH issue. Help please? How do I fix it or stop it getting worse?

Nutrient lock out?
Well watered my plants with great value drinking water. Ph 4.11. Didn't check ph until week 3. Currently upping it to 6.5 after I found the issue. Does this look like nutrient lock out? They were in root Riot starter plugs. And I fed the some clonex and great white microbs.

Quickly yellowing after possible over watering
That escalated quickly, within 24 hours we have lots of yellowing in lower center leaves on 1 Tastebudz and 1 Ethos: Adding cal mag to next watering. Would cal mag be better or Epsom salt at this point? Would a bloom tea help?

The leaves have become glossy and yellow
The last couple of days, the leaves have lifted a bit again and bent the edges, and the leaves are glossy, was it a mistake to keep the light on 24h the first week, or what do the last couple of pics look like? (I have now set the mode to 18/6) so as not to fry the plant

Leaves browning in multiple spots Lower leaves yellowing but have green veins.
One plants leaves are browning in multiple locations. I attempted to diagnose the problem with runoff tests. pH was 6.5 and TDS was around 900ppm, which was expected since they received nutes that day. Despite not spreading to other nearby plants, could it be leaf septoria?
