Looks like under watering, but isn't

[Styles]

These plants are about 40 days from seed. Plants are still in veg. Problem has been going on for about a week and a half to 2 weeks. Leaves are droopy and don't feel normal At first I was thinking it was under/over watering but I made sure to water perfect so I know it isn't that. Hopefully someone has some insight on what the problem might be as well as how to fix it. Any help is appreciated, thanks.

Looks like a PH issue to me. Test your water with no nutes. Water, then test your runoff. That will isolate the issue. You should be sitting around 6.

Try to get pics under more natural light instead of the HPS for 'real' color.
If that's soilless mix, you actually want to set your pH closer to 6.6.
When's the last time you re-potted, what are your temps, and how is your air flow?

i think you had better fill out the sick plant form ,so we can get a better picture
its not worth taking a shot in the dark about the problem

i guess uve all seen it a thousand times already -

your plants look fine, thats a slight p or k toxicity if i remember correctly.
i wouldnt do anything, that symptom usualy goes away as the plants grow (atleast in my plants/experiance)

I would transplant a couple to 5 gallon pots with fresh soil with dolomite lime, and see how they respond.

Excess Calcium

Excess Calcium

What Nutrient's are you using?How much of each with how much water? How Often? *Knowing the brand is very helpful* FloraNova Grow, FloraMicro, and used Advanced Nutrients Revive once about 3 weeks ago to correct small mag problem.

Why are you adding micro to the flora nova? Micro contains alot of calcium. Your tap water will contain some calcium. Flora nova contains calcium. Promix contains dolomite lime with calcium at least at the beginning. Excess calcium will cause a magnesium (like you think has already happened) or boron deficiency. It could cause a potassium deficiency but that is less likely. Stop using the micro.

8 Flora Nova grow. Flora Nova is the one bottle solution to nutrients, note this mix is almost identical to Canna Aqua Vega, and GrowGreen's Nute Recipe
n 217
p 54
k 257
Mg 46

Thats 8ml in 1 gallon water in ppms. Don't understand. No problem. You want to feed about 100 to 150 ppm nitrogen with every watering. Example: you want 150ppm n. 150/217 x 8 ml = 5.52ml per 1 gallon so about 1 teaspoon per gallon. Remember to really shake before pouring.

Ph is important! Optimum ph in a soilless mix like promix is 5.6 to 6.2 Best thing is to adjust your fert water ph up or down after adding floranova to 5.8 to 6

I've been using around 5ml per gallon. Tested water though and my tap water is around 8 PH, so it probably is a pH problem. I was kind of confused about it though because I have 2 other rooms that I also water with tap water, and theres no problem. But I will bring down the pH next watering and post results. Thanks to everyone for their help.
