Strayfox Iraqi Banger - DWC

Overall, they are doing pretty pretty pretty good. (Larry David style) I am trying to use less cal-mag this run because I have some N problems mid-late flower on other grows and now I might have/had a slight Mag deficiency. The plants didn't look super happy for a few days plus some purpling of the stems. I added 1.25ml cal-mag (about 50-60 PPMs of cal-mag total or 10-12 PPM of cal-mag per gallon) to the reservoirs 2 days ago and today I added just under a Teaspoon (5ml) of Espom Salts. It is 9.8% Mag and 12.9% sulfur. Hopefully the epsom salts won't cause more issues, then again if so, a res change fixes almost anything. EC 1.2-1.25 (PPMs 590-620). Today I increased the feed to 1.35-1.4. I really wanted the feed closer to 650, but I was a little heavy handed with the epsom salts and hard to get a perfect reading until it mixes into the solution. Plant on the right got 2ml/gal of karma and the left got 1ml/gal on the res change. Look at the roots you can tell which one got more karma. Funny thing is the plant with 2ml/gal of karma had less/no ph issues. Pretty much stayed at 5.8-6.0 all week. PH 5.5-6. I had a couple drops to 5.45-5.5 on the left res, which could attribute to the possible Mag issue, but I don't want to have to feed at 6.2+. I want to have enough nutrients readily available at 5.5-6.0 and not have to play the PH game. So I added the epsom salts. I may move these to the 4 x 4. They are filling up the 3 x 3 fast and the 4 x 4 will be easier to keep the humidity down so I don't have to run my dehumidifier as much. * Added 2 pics of the MAC1 clones that I transferred from soil to hydro. 2 weeks old since transplant today. I was a little nervous, but 2 weeks later and the roots are exploding. I did see a fungus gnat, so I am keeping these quarantined. They need a res change, more feed (EC .8 since the start), and some fans to start beating them up to strengthen the stems. I should top then flower in a week, but maybe I just flip them..... *Added 2 days later: I think it was more P than Mag deficiency, but could have easily have been both. I added a bit more feed and P and they started to look healthier. I did a res change, increased cal-mag slightly (20-30 PPMs), and switched to full bloom feed. Have a good week and thanks for stopping by! 🚀🚀
