Lets talk about the white widow for a bit. (middle plant in the picture)
I want to know why it isn't growing as fast (if fast is even the right term) as the others.
The stock is by far the thickest of the three, but the growth up top is scarce. What gives!?!?!?!

Hey there Heisenbud, so growth rate is determined by genetics and Vapor Pressure Deficit (VPD). Genetics is genetics , maybe you got a phenotype that's just like that, nothing you can do about that. The other thing is something more controllable. So basically even within a grow box there are micro climates, it's not as even as we think it is, which i did find surprising when i started to measure it . Vapor Pressure deficit is the relationship between humidity and temperature , so it's affected by the micro climate based on your temperature and humidity you're not in the optimal range, you should be around 25°C for that humidity ... seems like a small change, but clearly over time it does matter. Learn more about VPD here : http://pulsegrow.com/vpd Hope this helps ! 🚀

LED Kelvin Temp 3000k-6500kIs there a massive difference in colour temperature/kelvin of LED's if the lumens, PAR, watts, intensity and every other aspect you can think of is the same but its temp/kelvin is lower? I use a 6500k LEDs, may mix in or switch to 3000K for better flowers if its proven to work.

How short of a time frame into Veg can one go without added nutrients.Soil is 3 parts Roots organic og,1 part FFOF,1 part perlite, light bat guano, and microbes to the rootzone. I have calmag that I'll be adding to my feed but nothing else until I grab the nutrients I decide on. Safe to say I can go this short time (2 days) without added nutrients?Week 1

Photoperiods flowering early. Why will this happen?Why will a photoperiod plant flower early? Been a month and half in veg and is starting to flower. Should I switch light cycle to 12-12? I have two others in veg were planted only a few weeks ago in same tent. Should I sacrifice the growth of the others so that one can flower?
