Look at this plant

[umaherman4ever]

The thing is new growers come here and look at your plants and think thats what there supposed to look like. Those plants are all displaying deficiencies. So at this point its not for you its for the OTHER inexperienced growers.

"It is in a 15-20 gallon pot in Miracle grow potting soil. I use House of Garden Nutes, silica, Molasses, epsom salt and I’m sure a few others I’m not thinking of. Ro water. Ph’d at 6.3-6.5. Last TDS measurement was at 1186ppm. Water temp at 73°F. Lights off temps are 55°F-61°F. Lights on time temps are 64°F-68°F."

This tells me why you have a bunch of problems. Mainly the lights on temps. From the look of those plants you're running LEDs. Led light temps MUST be 80-84F. Those plants are Calcium, Magnesium and phosphorous deficient. Get the 'Lights on temps" up for your next grow add 5ml/gal of CalMag EVERY watering/feeding. Keep em GREEN till the end.

do temps with LEDs need to be higher because you are losing temperature at the leaf point from a typical bulb? Lights off temps can be lower of course yes?

Wouldn't hurt to.top.dress ur.pots with bone meal will aid in calcium and potassium always use calmag I use merical grow potting soil myself it does great I never have any trouble with led staying warm tho

do temps with LEDs need to be higher because you are losing temperature at the leaf point from a typical bulb?

When @zigzagman1960 mentioned higher temperatures for daytime I felt that he was recommending an overall or average temperature in the low to mid 80s. That seems to be an optimum 'daytime' or 'lights on' temperature range for best growth and health of the plants. Occasional 'daytime' temperatures that are a bit higher by 3 to 5 degrees are OK but most temperate zone plants slow down their photosynthesis, growth and metabolism as the temps go up. By the time the temps are in the low to mid 90s the plant stops growing until the temps drop.

I did not think that he was saying

Lights off temps can be lower of course yes?

Yes they can be lower than the 'lights on' temperature and the range of 65 to 68 is often recommended as the best for 'lights off'. As the temperature gets lower than that these temperate zone plants slow down and somewhere in the 40s will stop growing until it warms up the next 'day'.

From the look of those plants you're running LEDs. Led light temps MUST be 80-84F.

Mr. zigzagman1960, are you saying that the temperature range mentioned is because of using the LED lights? Will it will be a different temperature range if the grower is using a different type of light?

Just look at it

I am looking and I am seeing some really nicely done photos.

I really don’t need anyone to diagnose my plants as I’ve already done that weeks ago. They are healthy and producing massive amounts of bud as we speak.

Yes, you have done a good job with your plants and they are healthy looking and so are the flowers. You are there taking a look everyday and the time you put into it shows.

But, they do look "hungry" as the others mentioned. Too late this run of plants but upping the dosage of Cal-Mag the next time could help? Or maybe stick with the same dose of the Cal-Mag and try an additional touch of Epsom Salts once a month instead. The Epsom Salts, which help supply Magnesium, can help plants when the leaves show that strong green color in the veins surrounded by yellow leaf. Classic signs of a developing Magnesium deficiency as found on 'plant problem' charts.

Here’s for the first part of your question. Leaf Surface Temperature with HPS, MH, CFL and LED Grow Lights

as for the second part——a big YES
