Hi bud. 1.5ml/l of BioGrow at this stage is 0.5ml/l more than recommended. What signs did the soil give you that you are feeding more than recommended? To start plants/soil off, one would normally give half the recommended dose. You are nearly twice over that. And you're not actively up keeping microbial life, so what exactly are you feeding the BioGrow to? On top of that, Greenhouse Feedings as well? The soil is soaking in nutrients this little plant cannot digest yet. Salts are possibly forming and your plant may be experiencing a little lockout. LightMix comes pre fertilized, mostly Nitrogen, and has enough to last 2-3 weeks. You shouldn't need to give nutrients manually until the second week or so. And even then, mainly Nitrogen, CalMag and perhaps Potassium (BioGrow). In my opinion, water less. And only give her (dechlorinated) water at 6.0ph for the next week or so. Get rid of the GreenHouse Feedings until the plant asks for them. After she perks up, you can start the BioGrow again. 0.5ml/l for one week, 0.75ml/l the second week, 1ml/l the third week. After that, the recommendations are kinda hit or miss. The gradual increase in nutrients according to specific weeks is spot on though! From one BioBizz grower to another. Hope this helps, even just a little.

your medium is soaking wet. almost muddy. when theyre small. start with a cup of water and then wait a couple days and do the same and then weekly increase the amount of water your giving until your up to like 4-8 cups of water depending on medium and pot

looks like to much water and causing leaf warpage, Only water when needed.

Irgendetwas im Ionenhaushalt deiner Erde/Pflanze passt nicht, denke ich. Falls du Dünger ins Gießwasser gibst, würde ich mal bis sie mehr Blattmasse haben warten. Falls du organic growst, liegt's am pH der Erde. Würde einen Ring um die Pflanze gießen und es durch Diffusion und Mikroorganismen zu den Wurzeln transportieren lassen.
