Discoloration of leaves ( Fading )

[N00b]

Looks like a classic text book scenario, can the experts please shed some light?

-What strain, Seed bank, or bag seed (photo or auto)

• Bag seed

-Age of plant

• 5 Weeks

-Method: Soil w/salt, Organic soil, Hydroponics, Aquaponics, KNF

• Hydroponics

-Vessels: Type and capacity of container (fabric, plastic, etc)

• 80 Litre reservoir

-PH and TDS of Water, Solution, runoff (if Applicable)

• N/A

-PPM/TDS or EC of nutrient solution if applicable
127

-Method used to measure PH and TDS

• PH pen (HANNA), TDS (Local brand pen) both digital

-Indoor or Outdoor if indoor, size of grow space

• Indoor (2 by 2 feet)

-Light system List brand and wattage/spectrum

• Hydroponic the PPM & PH problem - #35 by N00b

-Actual wattage draw of lights

• I dont know

-Current Light Schedule

• Always on

-Temps; Day, Night

• 18 Deg C, 6 Dec C

-Humidity; Day, Night

• 50 Percent Plus always

-Ventilation system; Yes, No, Size

• No

-AC, Humidifier, De-humidifier,

• No

-Co2; Yes, No
+No

If growing Hydro some additional questions:

-DWC? RDWC? Autopots? Ebb and Flow? Other?

• Ebb and FLow

-Distance of liquid below net pot (DWC)
+N/A

-Temperature of reservoir

• 18 to 20 Deg C

-TDS of nutrient solution
PPM 127

-Amount of air to solution

• I dont know, 1x air pump which bubbles 24/ 7

P.S> it is only the top leaves that are fading, plus the growth is stunted.

PPM/TDS or EC of nutrient solution if applicable 127

Your plant is hungry. Be sure to feed a balanced product. It looks like iron may be an issue too.

[PurpNGold74]

Absolutely a hungry lady.

Hydro seems to be a calmag hog, and im seeing what looks like it maybe an early Magnesium Deficiency… have u supplemented any calmag?

Look into a good reliable hydro nutrient solution. Weed can be a voracious nute consumer. Youre definitely gonna need something to get her to harvest

@N00b

PH and TDS of Water, Solution, runoff (if Applicable)

• N/A

This is also SUPER important in hydro. Need to know this value at most times

@N00b

PH and TDS

Apera or BlueLab pH meters. Both brands are a tad pricey, but are accurate and dependable. They make meters that do both. Or if you get just a pH meter (don’t skimp on price), TDS meters are cheap. Very important tools.

[N00b]

No, cal. mag and i dont know if it’s a her yet. Lol. The leaves perked up when i upped the PPM to 230, thats a good sign no?

[N00b]

I got a HANNA PH meter, was readily available the closest substitute to BlueLab.

I mentioned the TDS and PH above, sorry for the repetition of questions.

[Bluntsmoke]

Ppms should be a good bit higher than 230 should be in the 500-600 range

[PurpNGold74]

@N00b

sorry for the repetition of questions.

Same here! Ull hear the same questions a few times because we just want to be certain before giving advice. No harm, no foul.

Get a hydroponic calmag supplement. Ur defo going to need it
