First grow Lemon Cherry Cookies

Wenn die angegebene calmag menge stimmt wäre dass natürlich viel zu hoch. Kann mir aber auch vorstellen, dass es an der website liegt. Die Blattspitzen wären total verbrannt und dunkelgrüne Blattoberflächen. Hashy hat aber auf jeden fall recht, das eine vollständige Nährlösung mit Blüte dünger+calmag ph 6.5-7.0 am besten sein sollte. Wenn der magnesium mangel weg ist PH6.0-6.5. wegen Wasser vielleicht erstmal ein Britta filter, eine osmose anlage ist auf lange Sicht auch immer zu empfehlen. Mit leitungswasser bei den dünge konzentrationen immer etwas weniger als angegeben, dass Wasser hat je nach dem wo du wohnst einen hohen EC wert. Ein guter Ausgang Wert wäre EC 0.2-0.3 bei mir sind es zb 0.7

Oh wow, I’m with Hashy on the calcium amount. Maybe you listed the amount you’re giving incorrectly? 113 ml per gallon. If this is actually what you have given, that’s an insane amount. Something closer to 3-5 ml per gallon would be more like it. 113 is probably more than a plant would want in its whole life lol

Also if your giving the plant the amount of calmag your diary states then your giving it way way to much.

If you are 2.5 weeks out from harvest I would not fertilize again... that is if its ready for harvest. If you feel the need to, then do half strength, looks like some burn on the tips. feeding its not going to doing much though this close to end of life. however It might have a bit more time in it then 2.5 weeks. hard to tell. Lots of white pistils yet. Also your plants where in flower at your week 3 in the diary. so you are on your 5th week in flower. Autos tend to bloom for 5-9 weeks depending on the strain.

I've used these powders. They are very potent. Also, you can't go by Grams per L. Depending if your water is hard etc. Also, you are PH'in these solutions right. Ph from these powders are in mid-low 6, for my water anyways. Start adding higher PK. But looks like it's ph related. You are flushing out that coco weekly to avoid salt build up.

I think you are too close to the end of flower to be adding more. It shouldn’t matter to much at this stage if you do not add any more as I think you might have plenty of nutrients built up in the soil because I see some slight burning on the tips. Hope this helps.
