While pH 5.2 is concerning, it's not catastrophic. Many nutrients remain available at this level, though in reduced quantities. However, phosphorus, potassium, calcium and magnesium absorption may be significantly impaired - and these are absolutely critical nutrients you don't want to lack during flowering. From this point forward, I strongly recommend continuously monitoring your water pH, ideally using multiple measurement tools for accuracy. This prevents extreme soil pH fluctuations and protects plant health. Start adjusting to pH 6.0, then gradually increase in small increments as needed when you observe the runoff approaching your target range. Your plant currently appears healthy. The absence of visible pH fluctuation symptoms suggests either your pH meter needs calibration/replacement, or you've been operating at this low pH level unintentionally by not testing fertilized water before application. Important consideration: Using distilled water for pH correction seems inadvisable. Without added fertilizers, you risk leaching existing nutrients from your medium and creating new deficiencies. If you do supplement with fertilizers, you must monitor runoff EC to avoid overfeeding. For your situation, I would temporarily switch to pH-adjusted tap water to maintain base nutrient levels and gradually reintroduce RO water later. Remember always verify both pH and EC before and after adding nutrient, and the runoff

Ever thought about adjusting the ph with some PH Up? And, flushing without nutrients. You flush to get a fresh start. Then resume regular watering and feeding schedule.

yeah run off is everything you can tell whats happening inside bro, if you know you have them in range from having sesors thats different talk but you need to know whats their PH and EC in soil, thats most important thant what you pouring in basically. espetially PH if its off they cant eat
