Yellowing leaves after first Mainline top. Light stress?

Pagusstarted grow question 3 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.

Why is one leaf yellow AND shiny?Plant has one leaf that is yellow on one side, and shiny/dark and curling up on the other side? From what I've read those are 2 opposing issues (light burn or nitrogen deficiency/or toxicity) the others are pretty much uniform, Could this be from getting water droplets on leaves?

2 plants, 2 Mars Hydro TSW 2000’s, need help with pot size/tent size configuration My plan is to flower these 2 girls in a SCROG under 2 Mars Hydro TSW 2000s (2x300W actual). I’m debating whether to flower them in 5 gallon plastic pots in a 2x4, 10 gallon pots in a 2x4, or 10 gallon pots in a 4x4. Does more area = more yield, or am I thinking about this wrong?

Mars Hydro TS1000 hanging height People with experience using the MH TS1000, between 24"-30" at 25% seems like a reasonable height to put my light over the plants in initial vegetative state at my 2x2ft tent? Thank you! :)

Light came on for about 30 seconds about 3 hours into the dark cycle So Im 3 days into 12/12 and I bumped my timer last night and my light came on suddenly during the dark cycle. I immediately shut it right back off. Was I wrong in shutting it back off right away? Should I be worried about anything?

Changing Lighting Schedule The days on the plants are since planting, so i was going to keep the vegetative light schedule until 5 weeks since planting, then start moving towards a 12/12. Is it even optimal for an autoflower to have a traditional 12/12 lighting schedule during flowering?

Yellow leaves near the harvest This would be my last week of fertilizer watering. And the plant has the leaves turned to the side and with yellow spots. Sign of lack of zinc? I would start making the flush from Friday, is it recommended to start now? In about 2 weeks I will harvest (I tried to water today)
