Strawberry Cough - Newbie DWC

She's stretching up to 2 inches (5cm) per day! - Thanks for stopping by, the Pruning Supervisor gets a treat for every like this entry gets 😁 D49 - 20" tall, almost an inch overnight, start of stretch D50 - didn't measure D51 - res change to normal flower formula (see image) - 23.5" tall D52 - 25.5" tall D53 - 27" tall - bases new growth has greened up, D54 - 28" - haven't been LST'ing, canopy isn't so flat anymore 😐 D55 - 30" new growth still yellowish (not near as bad as pictures) and a bit spindly, hmmm she is drinking a bit less now, did some more pruning **Issues** My previous bud-set formula was not dialed in, not bad but I THINK the super thin and yellowing base of new growth was a phosphorus excess antagonizing iron uptake. Also had a bit too much upper-tent airflow so she was getting a good amount of wind now that she's so tall. Moved the fans and hope she transpires a bit less now as well. She's going to need a much bigger defoliation next week, should have taken off more of the outside branches from the big secondary (now primary?) ones. **Nutes / pH** Need to look into how much Si/Fulvic is ideal, running < 1/2 mfg suggested just because I don't know, but this plant's new growth has always been more flimsy than my last long-internode plant. Could also be genetics or nutes.😗 She was slurping up EC 2 bud-set solution like a champ, Res even dropped to EC1.9 a few times before top-off. With the flower solution mix, the res EC is bumping up to 2.1 as she drinks, going to see how that plays out now that I (hopefully) lowered transpiration a touch and target ~EC1.8 The micros are in the Jacks A mix so I didn't have a very good way of increasing Fe to help her out, I topped off with the rest of the bud-set solution I made since she wasn't acting stunted in any way. Other plant didn't mind the formula as much, but new growth was just starting to show signs, lesson learned. Anyone use nitric acid in DWC? I took an educated guess on the available P from pH down, seems to be right to some degree now, which means I'm basically always going to be pushing higher P than I want. Been thinking I would like to have the option to adjust using half phosphoric/half nitric to give me even more P breathing room, there's plenty in the 5-12-26 and the extra N means I don't have to step up calcium so hard. **Training/Lights** Lights are 95% @ ~14-15", canopy is probably a bit too wide but still fairly flat. AC's been on so long co2 is starting to build up so upped DLI~43?, Careful Icarus...😎 Did some lite pruning through the week. Skinny lateral branches that are hanging outside and below the canopy of thick branches will likely get pruned during a bigger defoliation next week Going for quality > quantity with this run.
