yellow/copper appearance in some leaves after first run off watering
enthusiast_growerstarted grow question 4y ago
hi! after the first run off watering the girls seemed alright, sturdy and firm but some of the leaves (one leaf, 3 plants currently) experienced copper/yellow/orange tints .
this is only on old leaves so looks like mobile nutrients.
could this be cal-mag issues?

Looks like calcium deficiency. If there is coco in your soil mix cal mag is always required.

Copper Bronze look can be related to excess chlorine or iron.
Tap water usually has chlorine in it and its recommended to let it sit for 24h-48h to gas off before using.

First signs of burning from too much/too strong nutrients, as evidenced by the super green leaves.
Is there a product you are not feeding them with??? Wow!

Alguna carencia?Veo algunas puntas de las hojas que se están quemando y poniendo amarillas.
¿Qué opináis? ¿Algún exceso o carencia? ¿Debería subir el pH?
Quiero corregir el problema antes de que vaya a más.
Apenas le estoy dando nutrientes ya que la tierra tiene para 6 semanas: Batmix de Plagron

Cleaning the tent head to toe and the res. Iv tried using UC roots. Im really not sure what's going on and IDK what to try to fix it. Grow was going so well. This sucks.

Gelbe Blätter, mit Lila FleckenMeine Pflanze hatte Nährstoffbrand, dann hab ich erstmal keinen Dünger mehr gegeben. Jetzt bekommt die Pflanze gelbe Blätter mit leicht Lila flecken. Nährstoff mangel? Oder Blattverfärbung durch Blüte? Oder immer noch Überdüngung? Ich verwende BioBizz Starterpack.

Yellowing and Reddening of older fan leavesI’m experiencing a lot of yellowing that progresses into dark red blotches. I suspected a possible cal mag deficiency but after upping the dose multiple times I’m still having issues. Any recommendations on possible causes/treatments? Temp stays between 74-76, humidity around 60%

Brown leaves and red stems. Is this a calcium deficiency ?I had an iron toxicity recently that may explain the brown parts but it may look like calcium deficiency. There are many red stems too but it maybe something else like the bad Ph and overfeeding from the previous month. What do you think ? Thanks !!
