The silica is no worries Pal ...DP strains are double hard anyway & its only ever tiny doses,start it next week is fine .You can Start with zym if you like Pal ... may be a bit early as theres not a lot of root mass yet ?.

I will say the times ive had issues with babys are more often when I start straight off with aqua vegga .I much prefer to start with formulex & switch to aqua once there a couple of weeks old ... canna start is another option Pal .Both are more baby friendly & by bringing out the canna start id guess canna know the vegga is to hot for seedlings too . Seymour always used formulex with this line up to .May want grab some for the next seedling bro ?:smokebuds:
