So my new Mars Hydro FC-E1500 is here. Swaped the very old MarsHydro LED in the middle. Gave them a little bit more CalMag and for the 1st Wedding Cake Bio Grow. Very minimal trimming. I noticed that the leafs from the 2nd Wedding Cake are glossy like. I think it could be too much nitrogen. Stoped giving her Bio Grow 1 week ago.
Thanks for all the answers, i will flush both the weddingcakes out and see how they react. Also measuring the run off EC and PH and also soil PH.

I like this community already 😁 you guys gave me such good answers to my grow question. So I measured soil PH roughly between 7 and 7,5 so alkaline. Not good. I flushed with Phed water 5,3 and measured PH of runoff at 6,6 and ppm at 1480 . Repeated, measured runoff PH 6,3 ; ppm 1210. Repeat, but with PHed 5,0 water, runoff PH 5,9 ppm 1010. Stoped. 1st WddngCake took 3 flushes with total of 30 l of water.
2nd Wddncake got a flush with 25 l of water at the end runoff PH aprox 5,9 ppm 990 . Gave them both Nematodes because i saw a reduction in fungus gnats that is good. Almost none flying around. Fingers crossed. 😊
