Day 22: topped the older girls in prep for mainlining. Seeing some possible CaMg issues. Been watering every 3 days just around the stem. I've started to water "out", away from the center the last watering or two since they seem to be getting more roots. I was a little nervous to top given the deficiencies showing up today but I knew I was under feeding them and luckily it seems to be just a CaMg issue (maybe, feel free to chime in) since the plant is getting more "green" from the upping in overall nutes (A/B). I did increase feed from 1600 to about 1700 today. Increased A/B and CaMg. Was initially only going to increase the CaMg but the leaves still look a little light green so I increased them across the board. 1700 seems high but my tap water already has a base of like 400 EC so it's really only about 1300 EC of nutes. Watered them to run off for the first time since transplant to the 3gals today. Didn't want the soil to stay wet too long but they seem to using more water now. Also ph'd today a little lower, about 5.7 pH to help with the CaMg. Day 23: the marks on the edges/corners of the leaves are spreading a bit towards the middle. I just upped their nutes recently so I'm trying to stay patient. I was phing a little high (like 6) cause I was used to being in bloom so I'm dialing it lower to about 5.7 now to help. I know topping didn't really help but I feel like they will turn around soon. Plants looked stiff, no curling leafs or anything. Other than the suspected Mg deficiency I think they are doing ok. Wondering if it might be too much light.. had it about 12 inches from leaves but moved it to about 16-18 inches. Day 25: seems the deficiency is getting stable. I don't seen it worsening since day 23. Watered again today a little higher at 1800 (again, seems high but my tap is kinda hard and these guys need it). pH at about 5.6 for this mix. Seems it takes about 3-4 days for them to perk up after a heavier feed. Will keep at 1700-1800 for the next week or so to see how they do. The new growths look fine. It's kinda hard to tell since I topped 3/4 of the plants but the 1 runt that is running a few days behind has a basically perfect set of 3rd leaves. The 1st and 2nd set are a bit rough but not as bad as the others. I feel like between weeks 1-3 the plants up their nutes needs so much that I can't even keep up haha. It's also been very dry here so I think they aren't growing as fast as I'd like in veg. I added a humidifier and they are chilling around 50% lights on now. Day 27: Fed today at 1800 w/ full dose camg (5ml/gal), pH 5.8. No deficiencies on the new leaves. Growth has been stunted the last few days from topping but they seem to be back to growing today. Def thinking there was some light burn going on before so raising the lights was a good call. Just gotta give them time to recover from topping.. and the light stress.. and the nute deficiencies lol.
