  1. 1. bagseed
    2. vegging for 32 days (been slow moving times :()
    3. aprox 7.5 inches
    4. bubbler bucket
    5. im using peters 20-20-20, yes the soil fert. i use it at a stength of what should be right but i really have no way of telling its basicaly 1 tsp in about 2.5 gallons of water, but ive added quite a bit recnetly looking for either improvements or mistakes that i could learn from and nothing... id read of another guy on here who did the same thing and it worked alright but as of now i dont plan to do much mroe experimenting with hydro so im obviously not getting too far in that direction.
    6. im using fluros, 190 watts of.
    7. the lights are stay about 1-5 inches from the plants
    8. grow space is only a few sqaure space. nothingh large, nothing really small
    9. temp with lights on and the constant fan stays at a high of 90 and low of 83, humidity is about 35%
    10. and finaly thsi is my first attempt at growing pot. but mushrooms o nthe other hand :D
    im actualy not too sure what the exactly the problem is but ive def. got a little list made up of possible ones. from the picture you can see that all the new growth, and growth in general, isnt very green its very yellow. and nearer the tips of leaves the yellow will turn to brown patches which spreads leaves the leaf nice crispy anmd dry yea.... and the leaves are curling upwards.
    about an hour ago i added under a tsp of epsom salt which i read can help fix Mg def. i think it was. stil waiting for any signs of improvement...

  2. whats your PH ?, something is locking your nutes out big time
     
  3. I take it no meters, well then just scrape the whole thing cause you never going to get them back without a PH and a PPM meter. You just can't grow in hydro wiithout a means to check your PH, TDS, water and air. Sorry dude. However, if you plan on getting both of them, put them in straight water for a day and then give the about 1/8 strength ferts till you get your meters.
     
  4. Give the poor little thing some time. It's going to take longer than a few hours to see a change. It could very well take days before it can recover.
     
  5. Your light is too near of your plant. And yes you probably have a pH problem.
