Hi @Doughboy! I would start to look at the pH, your pH is not acidic enough for hydro/soilless. Try to stick within the 5.5~5.8 pH range or you could get some trouble like nutrients deficiencies/toxicities/lockout. Then, double check your nutrients schedule, did you provide anything in the water? In case you didn't, then buy some hydroponic fertilizer (such as MegaCrop) to add nutrients into your solution. A hydro run must be accompanied by a pH pen, an EC-meter, and a good nutrient line. Happy growing 👊

Soilless Medium w/o Hydro Nutrients – Some growers may start in a soilless medium and not realize it has no nutrients (with a soilless medium like vermiculite, coco coir, pertlie, rockwool, etc, it’s up to the grower to provide all the nutrients since they are inert mediums and don’t contain any nutrients on their own) which results in a deficiency if grower isn't providing extra nutrients. Soilless mediums are easy to grow in, but they do require the grower provide nutrients from the beginning.
