What airpump are you using? You want to match it to the stones. Its not the air being pumped in that creates had exchange its the surface agitation.
You did. It is not.
I'm using the alita al-40 very good surface agitation. Temp is 78 rh 38, I haven't done any top feeding. Southern ag and hygrozyme and I have a fan oscillating on low in the corner that hits both plants pretty directly.
Added magnesium and sulfur.
I would change the fans to make a cyclone type air flow any direct airflow needs to be minimal and I prefer as little as possible unless the plants are dense af. You removed the lower leaves to alleviate the issues of high humidity at the base of the stem already so all you need is air movement but not direct at this point. RH is far to low prob 55-60% would be good for your temps.
I'll adjust the fans to create the cyclone effect. Ill take out the cheap air stones and replace them with the 4x2 I have a couple extra. I'll also get the humidifier going, I'll update soon.
Sorry, res temps are stable at 67f
Sounds good. From here only pay attention to new growth the old stuff will not improve.
Did I miss this? Good call if so. OP PH should be 5.6-6.0 imo
I aim for 5.8 to 6.2, ph usually fluctuates up .2 in a 24 hour period.
All good there. Personally I like a bit lower
Never grown autos but heard sometime they can be finicky
Its weird that one plant looks like its having a hard time and the other looks good as far as I can tell. It's a bit frustrating not knowing a definitive reason why, I guess that'll come with more time and experience. It might be genetic, who knows. And I've heard the same thing about them.... after I bought all these seeds. So I'll grow out what I got and then see what you guys reccomended for the next round
