  1. Hey guys, my two girls are showing some problems and it is making me worry because it is spreading. The first two pictures are my Northern Lights and the Last one is the Sensi Star and its problem isnt as bad as the lights, the tips are just browning.

  2. I think severe calcium def.....maybe potassium too?

    complete a soil runoff PH test.......
    with PH corrected water (6.5-6.8PH for soil ) pour enough water in the pots so the water runs out the bottom of the pot ...collect & test the PH of this runoff water....post both the watering going in the pots and the runoff ph
     
  3. your sensi star is definately nute burn ,see the rustic red tips the're a dead give away so you want2 give them a flush using a mild nute solution ,mind whatever size your pots are 11ltr then flush with 33 ltrs ,6 gallon = 18 gallons etc

    use a mild solution of your veg nutes as also got a nitrogen definciency, = 1ml per 2 litres(or using gallons you'll need2 work out the amounts,we use litres over here in uk:D)
    afterwards your next feed on your sensi star should be 25% amount of nutes only for the next 2 or 3 feeds,depending what stage of flowering your at?

    as for your other ladies ,again depending at what stage your at in flowering but again flush & next feed flush again as checkin run off etc might be waste of time at this stage.(helpfull for future reference yes!)
    i'd say you've over fed them ,remember nute feeds on the bottles are based on you using a 1000 watt hid light so if using a less powerfull lighting set up decrease amounts of nutes by 50%,ie; 2-4 ml per litre on bottle then apply 1ml-2ml per litre;)

    all the best.
     
  4. I agree, totally looks likes nutes.

    Always hard to tell which nutrient is causing the problem and whether it's too high or too low.


    Did you make any changes to the nutes recently?
