This is my first grow and I'm having some issues. I'm using 600w mh, 20/4, 4x4 tent, organic self mixed and cooked soil, aged tap water 6.9 pH, 80*, <50 rh, soil pH at 6.6, plenty of air exchange and circulation. I have 7 clones at various stages. They have all recently had low dosage Organic fert (thought my soil mix was not mature) at the dosage for plants at 1 week of veg. Yesterday they were all given a mix of 1Tb epsom salt and 1 Tb dolomite in 1 gal of water. I'm not sure whats going on now. I was planning on buying a commercial cal/mag and trying that. On one plant I was thinking maybe it was potassium but now I'm thinking maybe it's nitrogen. Any help will be greatly appreciated. From the 19th. From this am. Here are the ones I thought needed the Mg the most, that was 36hr ago. I'm starting to think this one may need more fert, I'm not sure. These ones are my oldest, one already had problems. They have both been through pH and over watering. They have both been in better environments for teh last week and have started showing much more growth. I'm still not sure if I've truly corrected the issues. On the right.
