Hey, I need help. I keep looking up deficiencies, and I've come up with Mg or P deficiency. I switched over to lucas formula and tried to fix by adding a bit of epsom salt. 10 gallon cooler res. pH of 5.5 Temp of 60-65F. I do not have a TDS meter at this point. Mine broke, and I haven't had a chance, or the money to get a new one. If anyone can identify this def, please let me know! I'd also need a solution.
Deficiency i'm a noob!
