:smoking: mate everything I said on the 13th still applies...
-- the cold spells retard nutrient uptake and transport, especially P and micronutes, so the plant scavenges off the leaves for what mobile nutes (most micro's aren't mobile within the plant) are stored... this will magnify any other pH or simple lack-of defc.'s may be in play already... as mentioned that BE is very K heavy, not the best ratio for early bloom, more P is needed
--- the roots may have been damaged, which will also magnify any nute problems, slow uptake, etc,....the dry-outs, overwatering, cold, all will punish roots, rot them after getting damaged,.. shocks the plant and then it stalls,...
--- as such, the soil may have sufficient nutes present, but just aren't getting taken up well for the above reasons,... I see mulitple defc.'s happening, which hints that some or all of what I've said is happening...
-- pH may be a mitigating factor as well, guess we'll see soon I hope! Once that's figured, next steps will be clearer,.. Did you get a new bloom nute with more P than K? A lot of what i see is typical P defc. symptoms, yellowing, wasting, big necrotic patches,.. color fade and spotting at top is probably a minor micronute defc. kicking in,... Getting the temps up is also key, or nothing else you do will help much, that's a kinpin here next to pH determination,...
