So, I have had two full grows under my belt with some supervision from more experienced growers. Although this issue has shown that these growers didn’t have much knowledge about what identifying specific issues when things started going south. So, This round started off well, babies rooted fast and had a large number of roots. About week three of veg plants started showing what looked like Phos or Mag def.( brown splotches on some middle leaves, then ends would get crispy and die) sort of confusing as this mix has never shown this before. I added some Epsom salt and a little pk boost although this did not seem to help. Plants basically had stopped eating at this point. I flushed and let them dry out quite a bit and then tarted back with a recovery solution and PHd water and put some holes into the medium and raised the cubes to get air underneath. I am seeing some very slow roots starting to come out on some plants although all of them are drooping and just look very unhappy.Plants are approx 4 weeks old now , have been topped and are about 1’ 5 inches tall. Water temps are on average about 65 degrees.
Also, I am running at a 700 scale on my meter for my TDS measurements.
