Welcome to the 4th week of my mini grow :)
I've upgraded my tent with a decent fan to be able to provide enough airflow when my girls are flowering.
As you may have noticed I have no exact data on how much I water. Well, that's because I don't follow a strict watering schedule. I am watering them oldschool: when they need it, based on moisture of the top soil and the container weight.
A good approximation would be around 2 liters per plant every 3 days, but it varies every time due to changing temperatures, humidity etc.
The small one is now strong enough, so I started LST on her. I will not top her tough, since she already lost much time due to the one Cotyledon leaf dying during germination.
I used Plagron Grow Mix as soil, which provides nutrients for about 3 weeks. I'm going to start to give them low amounts of nutrients from day 25 on.
Day 24: Plants showing bright and slightly burnt looking tips on new growth.
Since I didn't feed them so far and the problem appeared over night nute-burn is very unlikely.
I raised the lights a bit more to make sure it's no light burn.
Probably a slight pH issue - I'll keep an eye on it.
Overall they are still in a good condition though :)
First tiny pistils have emerged on both plants, but they are too small for a decent photo.
Any ideas on the bright/yellowish tips?
Nute-burn is unlikely since I did just feed pure water to that point.
Maybe light burn? Moved the lights around 5 cm higher.
My tap water is around 7.2 pH
