Kan man ge plantorna för mycket ljus???

Precis som de flesta andra växter så börjar cannabis plantornas blad
blekna och dö om du ger den för mycket ljus. Sen dör resten av
plantan.

Googleskillsen visar sig komma väl till pass igen.

Light Excess

In general, too much light causes plant stunting. Even with no

superficial symptoms, internal damage may occur that produces

this. Leaves curl and may appear pale, edged with red. Plants that

have been allowed to dry are susceptible to sunburn. Excessive heat

and light break down chlorophyll, bleaching leaf tissues. Some plants

may suffer leaf discoloration's. Pruning damaged leaves, reducing

light and watering properly restore good growth.
