Purple Leaves to the extreme early in flower: NUTE OR COLD PROBLEM?

[darkone]

hey all, having trouble figuring out whats going on here. buddy has had many probs this run but there are a few showing extreme purpling as seen. My friend did put some humboldt white widow michorizzae in the botom of the buckets which had some residual white powder...... could this be it?
ideas appreciated

night temps are too low.. or could be genetic. but it looks like a nute issue too much mag?

 

[MrStickyScissors]

isnt it a phosphorus def.?

 

[MrStickyScissors]

are you using RO water? do you add pattassium silicate to your water?

Must be just me, but I don't see a problem there. They look gorgeous.

I am using RO water... do you mean like a nutrient additive with a high P value?

if your running RO water you have to add mag. and a pottassium silicate.

Either fix your ph or scale back some part of the nutrient feed.
