Yellowing leaves after first Mainline top. Light stress?
Pagusstarted grow question 4 years ago
Just checking in here, I am pretty sure this is light stress. it was at 18" (specs say 18-24" during veg) and she was likely pretty stressed after having her top cut off!!!
I have raised light to 23". Am I on the right track here?

I wouldn’t sweat it too much at this point but that does look like some interveinal chlorosis/yellowing. Could be a few things but I doubt it’s your light.
Especially that light - it’s not that strong. Keep doing what you’re doing for now tho I’d say.. and i agree I think it’s best to keep those fan leaves on for now until the node growth has established itself a bit more.

My soil pH was up around 6.9. I have been working this evening to bring it down a bit.

Using a Spider Farm SF1000D.
I also understand that some remove these fans when mainlining and others don't. I left mine on as the growth tips were small, but any suggestions here from a mainlining guru would be appreciated.

Should I switch reg to larger tent? Looking for opinions, first time mainliningIm currently mainlining a reg seed, confirmed fem, in my 27x27 tent, plan was to move it to the 3x3 once the last plant was harvested. Received my order of autos and am thinking of doing autos in the 3x3 instead. Just wondering if the 27”x27”x56” will be good for the reg?Techniques. Main-lining

Short period growHey fellow growers.
So I have an odd question,
Is it actually possible to start grow with 12/12 straight away?
And how will it affect my plants?
Let's say I have 3 autos and one photo.
Will I have anything worth the time if I start straight with 12/12 light schedule? Thanks youOther. General questions
