so I opened my cabinet this morning and overnight the stems of the fan leaves turned really bright purple??? is this normal yesterday they were green. No ferts have been given yet and it is in flower for about 10 days, Ph is good, perfect water, light ect. the leaves are a perfect green no burn or signs of stress? the weather has been cool at night 50s and it never gets over 80 in the box.

Do you have a problem with stretching yet? Cause a 30 degree difference from day to night can cause excessive stretching. More than a 12 degree difference will cause stretching.

No issues with streching at all it is very healthy and bushy, I just found it strange that over night it changed color dramatically. The plants from germ to flower have been exposed to 35 degree swings everyday and are doing fine. It is a paypa strain that says it does good in colder climates.

Phosphorus (P) deficiency:
Figure 11 is severe phosphorus (P) deficiency during flowering. Fan leaves are dark green or red/purple, and may turn yellow. Leaves may curl under, go brown and die. Small-formed buds are another main symptom.
Phosphorus deficiencies exhibit slow growing, weak and stunted plants with dark green or purple pigmentation in older leaves and stems.
Some deficiency during flowering is normal, but too much shouldn't be tolerated. Red petioles and stems are a normal, genetic characteristic for many varieties, plus it can also be a co-symptom of N, K, and Mg-deficiencies, so red stems are not a foolproof sign of P-deficiency. Too much P can lead to iron deficiency.
Purpling: accumulation of anthocyanin pigments; causes an overall dark green color with a purple, red, or blue tint, and is the common sign of phosphate deficiency. Some plant species and varieties respond to phosphate deficiency by yellowing instead of purpling. Purpling is natural to some healthy ornamentals.
