What do you guys think?

What do you think?

Setup:
Light: Spider-Farmer SF1000 LED
Medium: 5 Gallon Bucket DWC
Base Nutes: Advanced Nutrients Sensi Bloom Part A and B at 1ml/L
Advanced Nutrients Cal/Mag being given: 0.5ml per Gallon - Total Gallons of RO water is 4.5 gallons = 2.25ml of Cal/Mag
Does this look like a Calcium/Magnesium deficiency? Was thinking of bumping up the Cal/Mag to 1ml/per Gallon but figured I would ask here first. She is on day 56.

For starters, what's your ph? Looks more like a K def to me, but @Mañ'O'Green is the salt nute guru.

I posted this elsewhere last night and didn't get a response so I went ahead and swapped out the res and did 1ml of Cal/Mag per Gallon.
I should of grabbed a reading before I changed the res last night but it is usually around 6.3-6.5 towards the end of each week (day 7 or 8) when I do my res changes. I usually have to adjust the PH back down to 5.6-5.7 mid week.

Below are the readings from this morning after the res change:
EC: 1.5
CF: 16
Temp: 67 F
PH: 6.1

@Chubstrr Welcome to AFN.


Looks like a phosphorous lock out to me. Too much Ca is the problem.

What is the source and starting PPM of your water? If you are on municipal water you should be able to get a water quality report online. We are interested in the Hardness and sanitation sections. We need to know how much Ca you are starting with if we can. Alternately, you can estimate usually on the high side at half of the starting water PPM is calcium.

What Feeding schedule are you following?

@Mañ'O'Green
hes using ro water so must be ph or hungry?

@Mañ'O'Green Thanks for the reply!

I am using RO water from one of those machines outside of grocery stores. I fill up a 5 gallon jug. The PPM is usually around 30-50 PPM if I recall.

This is the feeding schedule I am following.

 

[Mañ'O'Green]

Are you using all of the products? What is the total PPM going in.

 

[Chubstrr]

I'm using everything on that list except for Nirvana, Bud Factor X and Flawless Finish. I believe the ppm was around 900 a week ago after a fresh res change.

ManOGreen is correct I think. I use sensi bloom and add no extra Ca/Mg and have had flawless grows. I think you may be raising the Ca level so high that you are locking out your P. Those leaves look like classic P deficiency to me. I do keep some Ca/Mg on hand because some strains are just plain Ca hungry, but I never use until I see the first signs of deficiency, usually little rust looking dots, not larger splotches. Something to kick around. Good luck and grow big.

@Heavily Medicated Thanks for the reply!

Are you growing Hydro? Do you grow autos or photos? What feeding schedule do you use?
