As soon as my plants go into flowering they stop drinking water, while most people say consumption goes up in flowering. Goes from once every 2 days to once a week maybe. Sometimes two weeks to get really light. They also produce super airy buds that have no filling but covered with trichomes. All my work wasted and I don't know why.

1) My first grow was outside and I had pH problems.
2) This time it's inside and I have treated the soil with a healthy amount of dolomite and the pH is stable. Water consumption has already slowed down considerably again ...
3) No visible problems with the plant that I can see. Maybe the purple stems or leaves too dark green might be N toxicity. This is day 17 of flowering.

I'm so disappointed, does anybody have an idea of whats going on?

These are the nutes I'm using with every watering.

1ml cal/mag (recommended 4ml)
8ml bloom (recommended 8ml)
2ml humboldts (recommended 2ml or more in flowering)

If you are flowering under CFLs, that's about all you can expect. You need a more powerful light.

that plant looks fine. All it needs is more light.

Edit: BTW, they use less water during flower because the light is only on for 12 hours (assuming you aren't running autos).

I understand CFLs are weak, but I've seen numerous people growing successfully with them. Of course it's not the same quantity or quality as with a real light, but they do have smokeable buds. Not just fluff.

You are going to need at least 100 real watts of twisty bulbs to flower a plant. And you likely dont need a full dose of fertilizer every time. Probably a combination of excess nute buildup and not enough light.
Those are 105 watts each

Also I see some tips pointing up, which from what I read is light stress, doesn't make sense since my lights are weak.

wow never saw those before. The grows i saw online that looked good like the grow weed easy tutorial had many 15 watt bulbs very close to the plant like a couple inches max and spaced all over. I dont know how to advise for 2 high watt ones. Sorry. Although they may need to be too close to work well and cause heat issues.

and you should have a read on your medium nutrient ec (ppm) cause that could also stunt your flowers.

Are you growing in soil or coco?

Around 26C with lights on and humidity 50%
Sounds about right. Idk they don't look over watered, not showing deficiencies and look healthy for the flowering time.

Possibly a nutrient ratio or concentration but I don't see any signs of that yet. Do they still finish well?

Your looking for a transpiration issue and usual culprits are high humidity, over watering, nutrient and light.

About the only thing I can toss out is do not water to runoff and keep the soil moisture a bit lower. Add perlite to the mix next go. You may need to change the feeding to a bit lighter when not getting run off and watch for tox signs to pop up as you may need a water only. Caution that doing this with synthetic nutrients can create some ratio issues so if you notice something going off then I would do a flush with very light feed.

What I'm getting at is soil can compact over time and this can affect aeration.... I think if you add perlite next run you'll probably solve this issue.

Try a fabric pot next time man! And agreed, they look good right now. Keep it up!

The bloom nutes shown in your pic are from a 3 part lineup from advanced nutrients... you're going to need the micro and grow nutes to accompany the bloom nutes.... using only one part of a 3 part nutrient line will not perform as desired. At least that's my understanding.



Good call! No nitrogen in the nute ratio combined with the not so penetrating light of a twisty cfl would inhibit big solid buds. And looking back the plant is starving for nitrogen.

I haven't read all the replies but if you're not going through water you may need more air circulation around your pots. Is it 26C on the floor or at plant height . Soil may also be too dense, more perlite? What are you using I don't see a mention of it.

Nice setup. Love those big cfls. They can make excellent buds with the right strain. With sativas, I wouldn't expect window breakers. I don't see a N deficiency at all.
