Over or Underwatering?

[Just1dude]

First grow. Coco Loco over Kind Soil. Distilled water only. 315CMH. Temps between 71-75, RH 52-56. Day 38 from seed.

I pick up the bags to test for weight and water when light. Somehow I've f'd up my Pineapple Express (pic 1) majorly and my Sweet Tooth (pic 2) to a lesser extent, both have started drooping and growth has stalled over the last week. My Critical + (pic 3) and Diesel (pic 4) are going strong.

Please see the attached pics and let me know what if anything I can do differently to get them perked up. Thanks in advance for any ideas.

You need to feed them some nutrients along with some cal/mag and if there drooping there either to dry or to wet,you have to figure it out.

-- I think you're wet-dry cycling too much, too extreme....As Nammy said, we can't tell by pictures what happened, such drooping can be caused by over or under watering,... this soil is supposed to be loaded with biology, more than usual because of the way it's made; it's them that are helping convert and cycle the organic goodies in there into forms the plant can take up... the soil life hates getting too dry or too wet, it harms them, along with the roots; if you don't recall how the pots felt when first made up, nice and well moistened evenly, then it's a guessing game if you haven't "calibrated" yourself well,... if they got too dry, it's not uncommon to have dry patches within the pot, and can oddly resistant to rehydrating.... damaged roots, whether by being too wet (smothering, O2 starved), or dried out and killed off, will be poor at regulating the plants water uptake and balance... If you need to, get a moisture meter probe and test it out, work with it in a unplanted made up pot to see how well it works , what it reads with soil at various levels of moisture, then test the pots at different levels,...
Use a wetting agent when watering once or twice, this will help it penetrate dry soils better, moisten more evenly... I like Coco-Wet for this

@Waira I think you hit the nail on the head. My wet dry cycles were too extreme. I was so worried about overwatering from the start that I was letting them get way too dry. I had a very good idea of freshly damp when I set up the pots, including weighing each individually. I was just over thinking thinks and letting them get too dry. The Critical + and Diesel don’t care much about water so they thrived regardless.

Thanks very much for the thorough response. I’m learning more every day.

The girls have since perked up and are doing well. The colts have established themselves but really need to fill in and then hopefully fatten up if I didn’t stunt them too much.
