purple stems only on sun leaves

my sun leaves stems are starting to turn purple but nothing else is wrong. it is 3 weeks into flowring. whats going on?

keep your eye on it.

plants use N during flowering and depending on how much N is in your BLOOM nutes it could be the start of N deficiency, or too cold night temps or it could just be strain.

ok the temp did drop a little bit more the other night. im using pk 13-14

what nutes ? CANNA? AN? GHE?


J

i think canna it also came with cannzym. i dont even know how to use it

look on the canna website www.canna.com for a nutrient calculator it will tell you how much cannazym to use.

the cannazym is an enzyme based product that helps to breakdown dead plant material in your medium.

what medium are you using ?


J

are you asking if i use soil?

they are dying. lack of nitrogen probably. You should be feeding them phosphorus now anyway, not nitrogen and in a couple of weeks to maybe 4-5 the leaves will drop off anyway. let the plant kill them off. it's supposed to happen. concentrate on the flowers now not the leaves. purple stems = nitrogen deficiency = normal for 3 weeks into flowering. not a problem at all.

please dont give out wrong information . plants need N in flowering too. If you cut out N all together you create problems and deficiencies. Yes during the last 2weeks of flowering your leaves will yellow due to NO nutrients but they should not be prematurely falling off. The leaves are like solar panels collecting light to turn it into energy for the plant.

YES the "medium" is the term used for what you're growing in, because rockwool or clay pebbles cannot be called soil.

canna pk1314 should be used at 1.5ml/1litre added to your nute mix during week3.
