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) clones
-Age of plant 1 month and 3/half week
-Vessels: Type and capacity of container (fabric, plastic, etc) plastic
-PH and TDS of Water, Solution, runoff (if Applicable) ph 5.8
-PPM/TDS or EC of nutrient solution if applicable 2.0
-Method used to measure PH and TDS. PH pen and TSD pen
-Indoor or Outdoor if indoor, size of grow space : indoor build own room
-Light system List brand and wattage/spectrum
Dimlux Expert 1000w EL UHF
-Actual wattage draw of lights. 1000w but i use 600w
-Current Light Schedule 12-12
-Temps; Day, Night 27-28/28 Celsius
-Humidity; Day, Night. 40-50
-Ventilation system; Yes,
-AC, Humidifier, De-humidifier, humidifier
What’s the run off PH and PPMS
Ppm was 1200 but PH dont know
Input and run off PH are critical for nutrient absorption with soil range being 6.3-6.8 and 6.5 being optimum, coco 5.6-6.2 with 5.8-6.0 being optimum. Out of range PH can lead to major deficiencies if not corrected early on and being precise on the input is a must. What’s your nutrients and feeding routine and do you feed to liberal run off each time. Low PH can often be contributed to a salt build up in the root zone from a lack of run off
I Use a 5.8 bc its on this. I will water them today so I can know what the ph run off
Is this coco or soil? If soil what brand
My best guess is a severe potassium deficiency. What, how much, and how often are you feeding her? What are the proportions of NPK in your fertilizer?
I feed every 3/4 days with 1L water + nutrition for 11L pots. And npk I send pic.
It’s soils but don’t know what brand is it
So your only using soil? No liquid fertilizers?
Agree with @MidwestGuy. My assumption is the K ratio of your fertilizer is not enough plus the ability to absorb what little potassium there is with the 5.8 PH
Good point. Potassium uptake drops off rapidly with a pH less than 6.0 in soil.
I suggest a proper cannabis fertilizer. Cannabis has unique requirements for nutrients.
@OGIncognito @MidwestGuy So this isn’t a severe case of painted nails as a N overage? Interesting how the tips look extremely burned.
This is concerning. You only give them 1L of water every 3-4 days?
@BobbyDigital That amount of water with nutes that often……
Should be closer to 3 liters every couple days.
Yes 1L for a 1 weed plant
I’m almost positive it may have started out with the painted nails but can only assume without run PPMs and the PH so low that it’s starving for potassium that and the point @BobbyDigital mentioned. Could be several things but getting that PH back in range is where I would start and a cannabis friendly NPK fertilizer
at the beginning i was giving i 5.8 ph then i saw on the internet that it should be around 6-7 ph in soil so i changed to 6.5 ph and started to get like this
Are you watering or feeding to ample run off? Most root zone issues can be avoided with this practice
