It does matter because there is ferts and fert salts sitting in the medium and it's in constant contact with your roots....mine way outgrow the buckets also but I still get the problem. Use RO or distilled water to rinse through them....check the runoff of what you get out of each basket.....both ppms and ph. Rinse them through several times....ro or distilled ph correct water only. That's how I do them usually excetp at the end of the grow. The buildup is most likely strictly in your medium.
Weedhound Reviewed by Weedhound on . Its Always Something... I think this is a phosphorus deficiency, but I am not totally sure. The edges are crispy and the new small leaves around the buds have yellow, crispy, turned down tips. The guide I read said a little P deficiency in flower is normal, but if P is what it is, I think I have more than a little. What should I do? PPM is 1150, pH is 5.6, double checked with liquid pH kit. They are starting Week 4 tomorrow. The last pic is what I would say is the worst looking one. Rating: 5
