Id up the temps to 80f if possible, and not let them get below 72f
AKBeanBrains has the real deal pre 2000 NL5. Id ditch the Feminized NL. I believe Expert seeds works with Sensi Seeds. Sensi Seeds lost their original NL5 genetics about a decade ago, and just advertise their NL, as NL. They dont advertise it as NL5 anymore. I dont care for Sensi NL. But if they still had their genetics from a decade or more ago, Id be the first to recommend them.
AKBB also has the original NL1, which is also some good stuff in its pure form.
[email protected] is AKBB email address. Message him for a complete seed list.
Dave will also send International for $35 1st class Shipping
The Green Stash on STRAINLY also has pre2000 NL5 at a great price. $5.25 a seed. I bought 40 of them. I also bought 2 packs of the AKBeanBrains NL5. IMHO you cant have to many NL5 seeds in your stash when in need for Indica based genetics.
True NL5 is as good as any Indica youll find if its the original genetics. Dont be fooled too. When you find a good pheno of it, it can produce paranoia, and can be extremely potent. A good as anything youll find.

Also most modern strains have both NL5, and Sk1 somewhere in their genetic line, and is a testament on how good that shit can be.
Ive had a NL5 cut since 2002 that will blow your head clean off, and if youre not used to potent weed, can cause extreme paranoia in many individuals.
Also make sure you supply your plants with a good supply of Sulfur, as it is a precursor to Terpene production. Its to late to really push it now, but keep that in mind for future grows. I use Epsom salts for both my Sulfur, and magnesium supply. I dont use calmag as I use Calcium Nitrate as my Calcium, and Nitrogen source.
