Mexican Airlines first grow

Hi there! We're missing some crucial informations here : do you check your Ec/Ppm and pH levels every time you feed them? If so, what was your last measurements? What feeding schedule are you following? Do you let the soil dry between waterings/feedings? I'm also using Biobizz and I always seriously decrease nitrogen doses (BioGrow) when blooming has begun, like 1ml/L only a couple of days during the stretch, then I completely stop using BioGrow. Also, Alg-a-mic should preferably be used as a foliar spray (at night), especially when you're having nutrients issue. As an emergency move, I would flush the roots for a couple of days, remove dead leaves and try to lower down the day temperature by 2 or 3 degrees. I'll be around, keeps us up-to-date, good luck with these beauties!
