Floracion con problemas

Thanks for the responses, I'll be updating the progress. Regarding the questions, the droopy photos were taken before turning on the lights, and the ones that look happier are from two days before the photo with problems. Today they are wilted with light and without it :( The water output measurement is pH 6.4 and EC 1.6 (750ppm to 800ppm). I hope the substrate dries out so I can water again with plenty of water to clean the substrate a bit and see if the root system gets unlocked; the roots look healthy. I think the most accurate thing is that there is a slight excess of water and now a general nutrient deficiency.

In some pictures they look good like they are praying up to the light and in others they look droopy. I'm curious at what points into the day/night cycles were the praying pics taken and same question for the droopy pics?

Hello Check your outgoing ph for confirmation that it's in the right range. If ph is good then consider some plants are more hungry than others and possibly raise the biogrow to 1.5 ml/l and the biobloom to 2.5 ml/l. The biobizz schedule isn't always spot on for all plants. Also some leaves will get yellowing when they're in the shade of the canopy so don't be alarmed if you lose a few leaves. If you're losing too many too fast then there's a problem. Happy growing. ✌️
