Got a King Ho Tep on each side to compare for the side by side. Each will be taken care of the same an weighed at the end for results.
nice plants keep up the good work........
I just did a foliar feed so it is on the 0.5 setting for an hour. I will lower it an raise it to 3w when the foliar is dry.
Yesterday was the first day i foliared so your assumption is incorrect on the magnification factor of water droplets. I'm well aware of that happening an thats why i turned the light all the way down to simulate evening conditions for an hour while they dried up. An like i said it started b4 i was foliar spraying.Thank you for also posting photos to show us the issues you were experiencing. Water, when sprayed onto a leaf will sometimes create droplets. If this occurs under intense light (like X2) the water acts like an additional lens, increasing the intensity even further. When this happens the light now has the ability to burn/damage your plants. This may be the cause of the issue and may not be happening on the Advanced side simply due to a lack of intensity. It has no spectral relevance.
I would suggest that in the future you foliar spray 1/2 hour before you turn your lights on, much the same way that most commercial farmers spray their outdoor crops in the early morning or late evening when the intensity of the sun is at its weakest (or has just passed the horizon).
If you are still noticing an issue, then it is likely nutrient related. For example the issues you showed resemble Magnesium and Manganese deficiency:
Magnesium deficiency traditionally affects older leaves first. Leaf tissue between the veins may be yellowish, bronze, or reddish, while the leaf veins remain green.
Manganese Deficiency symptoms include: necrotic and yellow spots form on top leaves.
We keep in touch with many growers using our lights and do our best to help whenever someone is experiencing an issue such as this. Hopefully our advice will help improve your grow overall. I can't say we've seen this occurrence many times, but every once in a while a grower does come to us with a concern such as yours. Thank you again for sharing.
hey Art,
don't stress about it, it's all good. it can happen to anyone, not your fault. there's always next run for a proper side by side.
I'm still looking forward to seeing those ladies flower under them leds
peace!
