Probably a bit on the cold side for them.
Not cold. Temps are exact. 27-30 in veg and 25-28 in flower.
Humidity is low. Around 35%. They veg under a 4 foot t5 fixture with 6 6500 bulbs. Only thing that i have changed over the years is now im in promix hp.
Keep the EC lower in dry conditions. Kelvin value of those lamps is very high for veg. Florescent lamps do wear out and need regular replacement. pH should be lower in veg, like 5.5. keep temps in the upper 70s.
Im in promix hp. Not hydro. 5.5 ph is to low. How long does a t5 bulb last? 6000-6400 is whats reccommended for vegging...?
What do you mean light level? Like my 5 month old t5 bulbs are already to weak for lush green veg growth?
No not the age of the bulbs but where they light fixture is over the plants. Too high or close to the plants might effect them. You can treat promix like hydro and it's alright to vary your feedings. Promix is consider a soilless medium so you want to follow hydro ph recommendation. I'd stay closer to 6 personally but if your run off is higher then watering with a lower ph solution will lower that for you.
How many times have you ran this plant?
First time with this strain. But i have 4 dif strains vegging and they all have pale leavea and purple lines in the stems.
humidity should be in the high 50's to low 60's try running at around 78-82 degrees in veg......
