I wouldn't start the final cleanse just yet, maybe another week. At this point it probably has about 3 more weeks to go. I usually wait until the big fan leaves are about half yellow before starting the cleanse.
No. Give your normal amount of water only when the pot feels light, same as when you were feeding throughout the grow. Make sure you pH the water to around 6.5.
Okay thanks for that, Would it cause harm flushing her now?
