Yellowing of the lower leaves during flowering is quite normal/common, but either add or up your P/K booster to help your plant, she will be hungry for phosphorous (P) and especially potassium (K) during flowering.

The damaged leaves won't recover, but it will prevent the other leaves from suffering the same fate.

Carences ?
Les veines des feuilles des Txerri Bilbo Haze deviennent légèrement bleues, est-ce une carence de phosphore ? Les feuilles de la Master Kush s'éclaircissent sur les bords, est-ce bien un manque d'oligo-éléments ?

Leaf discolouration. Nutrient deficiency?
Leaves are discoloured and clawed. Started about a week ago with yellowing of tips and clawing at top of the plants. Now lots of leaves are slowly changing colour. Thought it was nitrogen toxicity but my runoff is 330ppm. Are they deficient in nutrients?
