Week 4, 1st grow, does it look right?

cage said:

They have suffered some, no doubt. And thus so will the yield.
Since this is your first grow could you give some more details on the perfect numbers.
Nutrients?

Have you done water changes?
It doesn't matter if you have decent EC if the nutrient ratios in it are all over the place.

There is all sorts of signs that easiest advice would be to do water change with current info.

Water change every 7 days, religiously
Water temp 67
Nut. 1250 ppm
81 temp flower, 85 veg.
50% humidity
Ph 6.5 in flowering, 6.2 veg
5000 watt spider farmer light 16-18 over plants, raised from 12" in veg
Nutrients masterblend 10-30-20 Blossom Booster,

I never had a problem until, I uncovered the net pots.

Hmm..
How did you have the netpots covered before? I only see some Leca in the netpots from the photos.

The pH is on the higher side. A lot of guides say 5.5-6.5 and most point for the 5.8 as midpoint. Personally I aim for 6.0.
If you start getting too high, the micronutrients should be the first to show deficiencies, also the iron might precipitate out after 6.5 (depends on the chelate used in the nutrients).

Is that masterblend 10-30-20 Blossom Booster the only nutrient you use?
There is quite a little of certain micros, magnesium and no calcium at all.
So it probably shouldn't be used as a standalone feed.

Also there is quite a bit of ammoniacal nitrogen in it:
Total Nitrogen (N)
5.65% Nitrate Nitrogen
4.35% Ammoniacal Nitrogen.
Few points here, when plants consume ammoniacal nitrogen, the pH will drop.
The ammoniacal nitrogen competes with the plants uptake of potassium,calcium and magnesium.

Lastly I'd ask about the light aswell.
By wattage it seems HUUGE
Do you have any idea of the amounts of PPFD you are getting on your canopy?
If not, consider checking app called Photone for android/iphone.
Depending on your phone it gives pretty accurate results and gives you better idea of how much light you are actually giving them.

edit* googled your light and its probably the "Spider Farmer®SE5000 480W LED"
Still I'd suggest you measure your PPFD's. 1000-1300ppfd is pretty high amount of light and the plants should be healthy to be able to take that amount of light.

I think you got something similar to my setup.
Mine is 4x regular DWC's. Tote's specced at 90liters, but I fill em up with 70liters.
I do 1-2 water changes per grow. Though I have a pretty good handle of what my babies need and what I actually feed them.
I'm at ~3,5weeks into flower with this run.

But back to you.
Mostly I'm suspecting the nutrients untill you expand on what you have been feeding them except the Blossom booster which isn't a complete feed.
I'll check back in later.

My veg nutrients is Masterblend 4-18-38.

Blossom is masterblend 10-30-20

cage said:

Are you using those as a standalone? As in nothing else added?
Because there is no calcium in those and pretty low magnesium aswell.

Though that kind of nutrient bag is very common. I got similar from another company. No calcium in it either.
Those are more of a base kind of fertilizer, where you then add CalsiumNitrate and magnesiumsulfate (MgS).

Could you confirm have u been putting calcium in the nutrient solution?

Spider-Man said:

No I have not used any calcium. I have been working with Master Blend. Trying to tell them that I needed some kind of calcium. They thought I meant calcium nitrate. Which is a No-No for flowering. I told them I needed calcium, they say they sell Cal Mag products. I think I just need a calcium supplement. But no nothing about how to go about to get it and how much to mix. I mix 100 gallons at a time.
