Yeah DEFINIETLY keep the humidity under control for veg and flower. Everything this guy said was important and he knows what he's talking about.Humidity for veg should be 60-80% flower should be 30-45% Low humidity will cause plants to transpire more than normal which will cause them to dry out and die.Low humidity will also cause reduce C02 uptake slowing a plants growth. High humidity will cause a plant to not transpire causing over watering and promote bacteria and fungus. get a humidifier. every rise of 10 degrees in temperature, the air humidity doubles. I usually don't stress low humidity to much but 10% is extreme. slow down on nutes until she bounces back. get quality soil as well promix or foxfarms are great.
I'd drop the ph to 6.5
The nutes will probably do that if the water is starting at 7ph. Might even take it down to about 6.
Hell my dyna gro takes my 7.5 tap clear down to 5.3. I use my protekt to bring it back up to low 6's.
Ya know what, I have no idea what my nutes drop my tap water down to. I do know my tap water is 8.5ph lol. Getting a ph meter after my current grow - getting tired of not being able to tell what the ph is as soon as a make the water coloured with nutes. I am prepared to be shocked LOL.
I just transplanted in to 1 galon bags in to promix soil. my humidity is no where near 10% i mentioned it was at THE VERY beginning , its maintained now at around 40% with the new bags and temp is around 85 f. as also you can see the pictures, now with my galon bags there is no room for anything else in the box, so a humidifier would be outta the question. and a ph meter is around 100$ (cant afford at the moment) . now that ive transplanted, i watered them in to the new soil and put them back under the lights ( where do i go from here) when should be my next water, hence the new bags and the amount of water
