Hi, I think your lamp is too close... otherwise, water with pH-adjusted water. ...and reduce the nitrogen, it could be a calcium deficiency... and magnesium too. Also, what stage are the plants in? A full photo wouldn't hurt... Thanks, see you later!

Calcium / PH issues? Did I take the correct steps?Am I on the right track to remedy my plant's issues? Seems like calcium deficiency to me. Soil test comes in at just under 6.5, my reservoir water going in is 7.3ph, in case its actually a lack of calcium and not the PH i've top dressed gypsum (and epsom salts).

Should I start fertilizing or monitor the pH?Hi, I'm a beginner, about 10 days after switch, my lower and slightly higher leaves started showing signs of damage. I grow them in a greenhouse in strong sunlight, but I think that they don't get burned, I haven't fertilized them even once. What do you think of this?

Is this turning purple from temp change So it looks like what I thought was a brown spot (under the grow light), appears to be purple when I pulled it out to get a better look and stake it down. I did switch the light to something cooler, could this be from temp dropping. Not worried yet, just curious. Thanks

Chocolope Tent (Nutrient Lockout?)My choclope photoperiod plant gets brown spots while her sister receives too little nutrition. I think it's a nutrient lockout. (2/3 weeks left from harvest) Ladies get Plagron COCO A+B and Green Senations. I don't see any mold, air circulation is good.
