    What to do

    I don't like to defoliate, especially during flower. As I wrote in the other thread, I like to tuck instead of pluck. Tuck the fans below any bud sites that they are shading. Those fans are your plant's solar panels that generate food (sugar) to feed the roots and the buds as they develop. I...

    Recommendations for when to flip to 12/12?

    When the plants in veg are 1/3 to 1/2 the total maximum height you have available to you in your grow space. This doesn't include the distance the light occupies or the desired distance between the plant and the light. Little to none, except for removal of small sap-suckers in the shade at the...

    General Hydroponics Ph Down: How To Use This Product?

    I have the ph drops where you fill the test tube 1/2 full of water, add 3-5 drops of test fluid, then compare to a color chart. It's in 1/2 unit graduations ie 5.5, 6.0. 6.5 etc. Would it work to just keep adding the Ph Down to a gallon of nute water until a sample turns the color of the ph I...

    General Hydroponics Ph Down: How To Use This Product?

    If there's one thing that really grinds my gears with regard to nutrient products, it's vague or incomplete instructions. This product, General Hydroponics Ph Down, really takes the cake in that department. The "instructions" just say to add the product "sparingly" until the desired ph is...

    How to accurately measure pH???

    Jacks Classic 20-20-20, Flower Fuel 2-34-32, Cal-Mag. I don't know. I use 1/2-3/4 teaspoon Jacks, 1/4 teaspoon Flower Fuel and 5ml Cal-Mag per gallon. A local nursery brand potting soil for container and potted plants. The drainage is good. Taken today 9/13:

    How to accurately measure pH???

    That's very good to know, thank you. That explains a great many things about my pH readings.

    Is it possible to grow weed with only 1 fertilizer throughout the grow?

    Coast Of Maine offers a dirt that supposedly doesn't require any fertilizer at all throughout the entire grow, however you have to use fifteen (!) gallons of dirt per plant, making it somewhat prohibitive for an indoor grow. FWIW I've always had horrible luck with their products, but have never...

    Heat issue or led?

    I've never grown under LEDs, but I've put even freshly rooted clones under 600W HPS ~1.5-2 feet above the plant, no problems. When I looked at your plants in the pictures OP and saw the way they were drooping my first thought was overwatering. They look like they've been over watered to me.

    How to accurately measure pH???

    It's not something I have ever done before. Sometimes I will flush 3gal pots with 3-6 gal of water if I overfeed or otherwise mess something up. I just wanted to see if I could get the pH in the right range, which I did eventually. Totally agree, but according to the nutrient chart, if the pH...

    How to accurately measure pH???

    So the test I did immediately after collecting the water is more accurate than the test I did on it six hours later, due to the delayed action of the buffers?

    How to accurately measure pH???

    3 gallon soil pots. Yes, that is what I noticed. With each 3gal flush the pH went up ~0.5. What I don't get is why the same runoff water that was testing at 5.0 a minute after I collected it is now testing at 7.0 six hours later, after having just sat in a glass on the kitchen counter the...

    How to accurately measure pH???

    I've been growing for many years but I am totally new to pH and tbh I don't understand it at all. To make matters worse, I cannot seem to accurately measure it no matter which method I use. For example, I recently purchased a pH test kit where you fill up a test tube half way with the water...

    Yes, that's what can happen after you re-veg from flower - "gangbusters" of shoots and nodes. I agree. What may be "right" for you with your setup might be "wrong" for my setup and yet "mediocre" for a third guy's setup. It's always better imo to increase light than pick leaves to get deeper...

    What causes this problem in cannabis plants??? (PICS)

    Yeah I was playing around with this concept earlier and came up with something like the following... Ok take Jacks Blossom Booster 10-30-20 as an example. I think this means that 10% of the total weight is N, 30% P and 20% K. Therefore one gram would have 0.1g N, 0.3g P and 0.2g K in each...

    What causes this problem in cannabis plants??? (PICS)

    I was just re-reading the thread to see if I missed anything and this caught my eye. Dam I was born in the 80s, grew up in the 90s and you were growing weed in the 70s??? I didn't even know what weed was until the early 00s! That's absolutely amazing that you figured out how to do it back then...

    Mars Hydro light won't turn off

    Get one of these, they are reliable as a heart attack: Plug the main grow light power supply cord into the timer, then plug the timer directly into the wall and follow the instructions to set it to 12/12 or whatever schedule you want. It comes with excellent instructions. I've used one of...

    I mostly abide by: If it ain't sick, don't pick. Those fan leaves are your plant's energy factories during flowering (all the time really) and also serve as a nutrient reserve in case of a deficiency (the plant will pull the nutes it's low on out of the lower leaves and transport them to the...
