Without the PPM measurement, we are just guessing what the problem could be. It could be too low of PPM indicating it needs a feeding, or too high of PPM causing a nutrient lockout. Without the pH measurement, we don’t know if the medium is in the acceptable range for nutrient uptake. If the pH in the medium is too high or too low, you could get nutrient lockout and see deficiencies.

But it looks like you’re close to harvest so I’m guessing you’ll just ride it out?

Cheers man!

Thanks for the guest suggestion! I’ll add them to the list of potential guests.

What pH and PPM are you running in that hydro setup?

[mrgrowit]

What nutrients have you been feeding the plant and how often? Also, what is the pH and PPM of the soil runoff?

What is the pH and PPM of the soil runoff? Sounds like you’re growing with organic inputs; what fertilizer have you fed and when? Could be anything from a lack of nutrition, imbalance in the soil, pH being off, or something else.

I concur with @CamZ

I’d rock two lights with a flowering coverage area in that space – one for each side of the grow space. Here’s my picks for the best LED grow lights for that space:

Hard to tell you for sure. A soil runoff pH and PPM can help us see if things are in their ideal ranges or not.

How much fertilizer did you use and when did you apply it? By just looking at it, I suspect magnesium deficiency:

How does the plant look? You might be able to just ride it out if the plant is fine since you’re so close to harvest. But if you think it needs a flush, go for it.

Looking great so far! Nice job

[mrgrowit]

Coming along pretty good JD! Thanks for sharing

[mrgrowit]

Looking good Alex!

I’m late to the party here. Seems like all your questions got answered but let us know if you have anymore. Also I wanted to mention the list of best LED grow lights for a 2×4 coverage area since you asked. See a list of my picks here:
