Continuing the discussion from Leaf discoloration early flower:

How about filling out a Support Ticket so we know what your setup is like and hopefully help you tweak it to your situation.

COPY/PASTE the below list into your forum post.

Answer these simple questions the best you can.
If you do not know, or do not use something; Just say so; Or post
NA (non applicable)

-What strain, Seed bank, or bag seed (photo or auto)
-Age of plant
-Method: Soil w/salt, Organic soil, Hydroponics, Aquaponics, KNF
-Vessels: Type and capacity of container (fabric, plastic, etc)
-PH and TDS of Water, Solution, runoff (if Applicable)
-PPM/TDS or EC of nutrient solution if applicable
-Method used to measure PH and TDS
-Indoor or Outdoor if indoor, size of grow space
-Light system List brand and wattage/spectrum
-Actual wattage draw of lights
-Current Light Schedule
-Temps; Day, Night
-Humidity; Day, Night
-Ventilation system; Yes, No, Size
-AC, Humidifier, De-humidifier,
-Co2; Yes, No

If growing Hydro some additional questions:

-DWC? RDWC? Autopots? Ebb and Flow? Other?
-Distance of liquid below net pot (DWC)
-Temperature of reservoir
-TDS of nutrient solution
-Amount of air to solution

Always try to upload a clear picture in white light of any issues you may have to allow the community to assist you.


So from the top closet grow
-ilgm blue dream auto
-9 weeks old
-black plastic//rootspa
-PH varies each day between 5.5-6.1
-current ppm is 500 (she’s eaten down to 400 in a week)
-some ph and ppm pen
-temp day gets up to 25C humidity high is 54
-temp night is 21C ish humidity mid 30s
-no ac do have a humidifier and ordered a dehumidifier
-no co2
-340gph air pump
-no ventilation (yet)
-sf-2000 not sure the wattage pull
And that’s about all I know in a 5 gal bucket


I think that SF2000 is 150 watts IIRC.

How many plants are in your space and how large is the grow space?

What is your water temp?

How far below net pot is the liquid?


I keep 1 inch gap below net my closet grow is in a 24x48x60
I have more but I’m less attentive to my ladies in the soil they do their own thing pretty well and my water temps range between 16c and 23 c I use the hydro guard as well


Slightly too cold at 16 Cel and 23 Celsius could lead to Pythium. 65-70 would be ideal res temps. I would also have the net cup closer to 2” above the nutrient solution. With a 4 sqft grow space I would recommend a minimum of 35 watts per sqft of quality lighting. Most reputable lighting manufacturers use the Samsung diodes B/H series with the LM301H being the top of the line.


Having adequate light means plant can uptake a higher salt concentration due to increased photosynthesis. You would benefit from double or triple the light already in use.


So what your telling me is to increase my lighting before adjusting my ppm up or what

No, upgrade lighting period. The other stuff can be worked out but lighting is paramount. If light aint right the rest dont matter. To a point.

So an sf2000 lm301b isn’t good enough for a single plant run ? @Audiofreak would you have a suggestion for a light improvement maybe

Not personally familiar with your light but i have a 2x4x6 tent using a HLG 260XLR TYPE.
