<span class="link_user">@trondheimdude</span>, are you sure that they are not too close to the light ? if it's salt build up you can try to flush her up a little bit :)
<span class="link_user">@GiletJauner</span>, Thanks the vertical growth surprised me too. However, the cali og seems to have stalled and starting to show signs of heat stress - though only 24C and 45% RH, thinking a salt or Ca buildup from my hard water. Tested runoff at 3500ppm :|
