ist my ec setting To high for this stage 3rd week

Hello @Shamall72 ! It depends from the plant. In general no, its not too high but some plants might find it a bit high. In fact 1.4 ms/cm is like a thin line. What you have to do ( considering you are in soil ) is to giving nutrients every third or fourth watering. That will keep you just fine. Happy growing ! :facepunch:

You are a Luck Guy, for choosing resiliant Genetics, as for start to feed so early so much would have killed alot of seeds. Normally your soil keeps food for minimum 3-4 weeks. And there is no need to feed aplant before the 4th node. And if you really want to feed from that point on start with 25 percent of the recommend amount. As it seems your plant was not Hurt ( but icant see a lot in led light.. my advice for you... go on slowly.. give her abreak for 10 days with only Phed water. After that take half amount of Biogrow. Then if she responds well you can add some biogrow happy growing

11 liters will last you several weeks (7 or 8), stop feeding, it's not necessary and can really hurt your plant. That EC is more appropriate for flowering plants
