I have been watering with 2mL/gallon cal mag once per week, letting them dry out completely then watering with ILGM’s Bergman’s nutes at half strength (bloom and booster). So basically watering twice a week once with nutes the other time with cal mag. Just watered today with the cal mag all the plants except the shorty gets about half gallon each watering(enough to barely start to get runoff) I have been measuring my runoff ppms with each watering and all of them are in the 1000-2000 range with no significant changes from the previous measuring in any of them. All water is ph’d to about 6.5.
Now in the last week have been running into some possible issues. First off I got sick for a few days and neglected them a bit more than usual and when I cranked my lights to about 100 percent I had a humidity issue I believe. When lights were on temp would be around 85 but there was about a full day or so RH hung under 40 percent ish. I have since fixed that and am able to maintain my RH at around 50-60 with lights on. I think I also let them dry out a little bit too much before watering today because my leaves seemed to start drooping all over and had some leaves yellow and die toward the bottom which scared me but not too much because seems like the tops of pretty much all the plants were not showing anything off but now it seems the yellowing is getting a bit higher up the plants and worsening. I have been occasionally LSTing still and I raised my lights up about 6 inches so they are about 20-24 inches now at 100 percent each. (This helped with the RH problem on top of me setting up another humidifier outside my tent that is on a smart plug to auto turn on when RH dips below 40 basically as a backup to the one in the tent and it is set up in front of my 4 inch AC infinity with smart controller intake fan). Seems like since watering today my plants are done drooping but I believe the yellowing of the fan leaves towards the bottom is continuing.
Here is my RH and temp chart from this last week (notice the fluctuations)
Here are pictures I just got done taking trying to show the yellowing of the fan leaves.
Help! What am I doing wrong and what should I do?
Thanks!
