At the start of week 8 I drained the system, and refilled leaving out the grow nutes. Although I also forgot to add calcium so over the week a calcium deficiency started.
@moeGrow,i know that sativa strains dont like hard feeding ,some take it ok but go easy,just in case ,i see some spots on leafs and some slight burns ,idk cause the light isnt good to distinguish colors if there are problems with the plant,in general a plant needs ph being stable not fluctuating.that can lead to problems

happy growin
@Blacklisted, I let the ph drift between 5.5 and 6.2 to allow for uptake of nutrients all the way along the range. As they eat it climbs higher, I've also increased their feed to 1.9 EC biggest part if that increase is the magnesium sulfate as they cant seem to get enough. Sativas generally dont like strong nutrients but these girls are pretty happy.
