When I got nervous about a potential disease, I clipped off the spots from the fan leaves to look at them closer under a microscope. I’d say all the first big fan leaves are starting to lose some color, but the ones I snipped are the most yellow. At 32 days old, is it just normal for them to start dying off like this or is it indicative of something else?

<p style=”text-align: left;”>There are several yellowing leaves. One of them is progressively yellowing pretty fast. I’m sure the plant isn’t about to just go yellow and die off or anything, but it would be cool to know why I’m seeing this. I lightly pre-moistened the soil in a bin before transplanting. My gut says it’s due to a bit of transplant shock or perhaps some inconsistent moisture in the new soil.</p>

Cool thanks. They’ve been in the 7 gallon pots for 4 days and haven’t been watered again yet so it’s a bit early to say wether they’ve been “consistently moist.” In the 1 gallon pots, well that seems a bit more difficult to keep at the optimal moisture level for organics so those were mostly being watered on a wet/dry cycle. Now in the 7’s I will endeavor to maintain a relatively even moisture. I have a feeling the old soil where most of the roots are has become dry. I’ll give it a shot with a light watering tonight.

I’ve got a few leaves that are lightly fading at the base of the plants, 9 days into flower. I had been blending in veg nutes with bloom nutes and tapering that down. Never the less, is this indicative of the beginnings of an N deficiency?

Watering these big pots can be weird. I was wondering if perhaps a dry pocket or two would cause this, but again it’s all at the base of the plants.

I want to nip it in the bud and give them some more N sooner and later if they need it but I don’t want to jump to conclusions.

Also possible that I am overwatering some. It’s kind of difficult to judge still. Possible cause of this?

I’ve got some burnt tips but not too bad. However I’m not certain if it’s from overfeeding or some light stress. I had my HPS too close for a while. The recommended distances are all over the map. I jacked it up to play it safe. Lex Blazer’s recommended lux for HID is profoundly lower than what 99% of people have said on the forums over the years. Rather confusing..

Anyways here’s the main question, if you get burnt tips from overfeeding, where does that show up on the plant? Top of canopy only? Fans only? Sugar leaves?

My burnt tips are 100% concentrated in the top 3-4” of the canopy. No burnt tips where there is less light.
