I've been told that I should use dolomite lime as a ph buffer, is this still true with this soil? (Haven't done it yet, was planning to top dress)
How do I lower nitrogen when I'm not adding any nutrients?
To avoid the mold infestation, do I need to transplant into larger pots to solve the problem or do I need a dehumidifier to fix a larger problem?
Sorry to ask a lot of questions, I'm new at this! Thanks a lot!
not a problem man. We all were new at some point. And this is what we are here for.
ok. first things first.,
when adjust ph , you need to balance the difference between what you currently are and want to be. its the medium. if your soil is 5.5 and you want to get 6.0 then adjust to 6.5 in water and our it in. a little high and it balances out.
ok next. good job not using nutes with FF OF in veg. you dont need to adjust it. just transplant into larger container and this out the waterings. When im in young veg as I call it. They use very little water. So I adjust accordingly. Lightly saturate my soil through out, and then add to the new pot when I have the correct moisture. To me it seems like, just barely damp is premium. you get to water and feed more often with out worry of over watering.
You need to repot them because , in a solo cup oxygen is low, your plant cant grow, it may even be bottomed out in that cup already. causing root rot. and its just plain ol time to do it.
if it is auto flower repot into a large container 1 step before final pot. long story auto flowers are the excetion to the rule of how many times you repot. the answer is 3 lrage incriment repots.
ok if you take any info from me take this to heart and keep it forever.
your room should be
75 degrees, 40-60% humidity at all times. you may need a heater, ac, humidifier, dehumidifier. What ever means necesssary to get the job done. And tons of GOOD light and Tons of ventilation. if you can do this , your 75% done.
ok mold is , one of three things
too cold at night
too much nitrogen
bad ventilation
small changes in environment cause lots of problems.
Best to be dead on at all times.
and last but final, I hope your not talking about those 3watt led ufo's from ebay.
I use LED as well. However. I learned my lesson. Ebay isnt for buying led grow lights. those are sucker lights. only suckers buy them.
I used Kessil H380 ufo's. I am currently doing a demo on those led's as we speak. I would not and repeat would not try to flower a cannabis plant with anything under a 350.00 led light.
If you have those cheap lights they will all die at week 4 of veg. not enough power to get a good par rating. Im not knocking on your system I dont even know what you have . but if you do. your gonna need some help with PAR on those plants. 400 watts or more. period with led. with uv and IR.
