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.

Leaves Turning Yellow - RQS Watermelon AutoHi GrowCommunity! I am currently growing a RQS Watermelon Auto. The plant is in week six and started flowering two weeks back. I did some LST which the plant handled quite well. I am seeing leaves turning yellow starting from the inside. Is it missing nitrogen? Thx in advance..

Yellow leaf tipsHello,
I think I have a slight over-fertilisation.
Could someone have a look at this. And could someone explain to me in this context whether and how bad it is that the water does not flow through when watering. I have never had water under the pot.

Natural or Problem?Is this natural yellowing or is there a problem? pH to 6.3 and runoff is 5.7. The stem is awfully purple, watering/feeding is where I struggle. 1st pic - 4/21 and 2nd pic - today(4/24). Seems to have escalated over the last few days. Do-si-do auto about 10 weeks.

The clone has bad leaves. Need helpTell me, friends, what's wrong with my clone, I still can't figure out what's missing or too much. When I gave him just water PSH 6, ppm 10-15, he turned yellow. When I added water with a minimum amount of fertilizer for 1 week for vegetation, it also turned yellow.
