I checked out a couple of diaries that use mega crop. At week 4 people are using 1 gram per liter of water. So that would be 0.25 of a gram per 250ml of water. You can try that and see if she shows more growth.
She looks healthy .Not sure how she managed to get stunted. I would have expected more growth out of her before she started flowering. It looks similar to your other grow. Is a 0.25 of a gram of megacrop in 250ml of water giving you a TDS of 900? Do you know what the conversion factor is on your meter? Is it 0.7 or 0.5 ?
@NaturalGrowG, sorry I forgot was it biobizz light mix? Also yes I did finally grab a cool mist humidifier for my Bloody Skunk grow but I still use clear plastic cups with holes poked in them for the seedlings when they're small seems to help out a bit.Trying to keep 65-70% humidity when they are seedlings is hard to maintain in my house.
Yay , you started her in a big pot! I think your off to a good start. Did you ever get a cal/mag product? You probably should just to have it on hand just in case it's needed.
I'm not familar with doses for mega crop. You can use your grow question I'm sure someone who uses mega crop can give you better advice on how much you need to use.
@LiquidAlpaca, youll learn along the way. Take your time to look and study your plants. Even the best growers are struggling sometimes. All i can say is imo you give not enough at once and too often water. I water once aprox every 5 days now. Nutes less is more says everyone ✌️
