Ask Us Anything: Sharing Knowledge 420 Style

I have been and got some sensi grow coco a & b as well as some great white, re potting them into 20L pots today.
 
They will pull around quickly with that. give them a good drink with ec of 1.5 (thats with water starting at 0.3ec) and put the great white in the coco when repotting. Plants will take off guaranteed.
 
I really don't know. id be guessing around 2ml/L.
 
I have a 1.2m x 1.2m x 2m space...
I currently have a 400w light producing roughly 39,000 lux on my canopy... If I added a 600w that would add another 63000 lux...meaning Id have 100,000 lux... I heard that after 90,000 lux solarization will occur, damaging the plants?? Is this true... Should I just get another 400w giving me 78,000 lux? or is that still too high???
 
def be fine as long as you can manage heat.
 
its pretty normal in coco if the coco isn't fully conditioned. just make sure you are feeding nutrient everyday and that ph is between 5.4 and 5.8.
 
whats in your mix? You want calmag, base nute and root stimulator.
 
ok drop ph to 5.5 and give the coco a good drink with run off. I have this happen often and its usually that the coco isn't fully conditioned. I also use plagron.
 
yes but it needs fully conditioned with the nute mix. otherwise it will cause calmag and phosphorus issues.
