Hi guys, what's up with this plant.

Dwc leaf problems
- Thread starter Smiffy_420
- Start date
The most common problem is over-feeding, which leads to unhealthy plants.
950 ppm would fry my DWC plants, and I never go above 450 ppm (EC=0.9).
pH is the second most common problem. Keeping it a bit higher around 6 will lead to fewer problems.
CalMag need is another common problem.
When only a few leaves are affected, it can be caused by spilling nute solution on the leaves.

I would say a slight Cal-Mag deficiency. Up the cal-mag by 50 PPMs and lower the overall to less than 800 PPMs. It can be caused by PH problems as well. So keep that dialed in from 5.8 to 6.1 as a good target range and it gives you a little more room for error as Hydro can run 5.5 to 6.4 as the extremes. The final thing to watch for is root rot. I recommend Botinicare HydroGuard as a prophylactic.
@Simplicio @Mañ'O'Green Thanks lads, i cut my ppms and upped the ph a bit, i wont be using hydrogaurd, its too expensive 30euro for a 240ml bottle, ive read its not needed if you keep res temps in order.

- is it just this one leaf? Or 1-2 others? I've seen this weird symptom several times before, leaving pale green patched that dry out fast, may even stay green-ish after,... It fits no toxicity or defc. symptom well that I find, though it presents sort of like P defc... but that usually has full on browned-out necrosis, not these pale patches,... One guru I presents pics to a while ago said it looks like an infection, not sure if bacterial or fungal,...This is not a nute splash symptom in any case,...
Yeah no its not nute splash anyway, its only really on this leaf and its pair on the opposite side. Ive done a 3/4 water change and added some h2o2, see how it goes over the next couple of days
