Not a pro by far.. but I have witness this so much with this ffof soil... to me I feel like its a k deficiency...they use up so much during heavy flowering..seems like using pk boosters made it worse... not a burn but a deficiency....like you...with not many nutes used, the tips of my leaves began to brown and burn...I started using bembe 0n- 1p- 3k... on my next grows around weeks 4 - 8... things got a lot better... jm2c

I will look into to that method if I use the same soil again. I appreciate the advice.

I think your selling yourself short. Dispensary weed IMO is a race to the bottom. Everyone in the supply chain is trying to maximize profits, over time that means reducing inputs and cutting corners. With experience, the right equipment and the patience to dry and cure properly you can blow dispensary weed away. Go with photoperiod plants as a start.

Lots of white pistils still on your plant and the calyx need to swell some more. Be patient.

Hello again. I have a few sub par images of the trichomes. Can you tell anything from these?

Looks to me since it starts at the bottom and takes over the whole leaf that it is a nitrogen def. Have you transplanted at all? Medium could be used up of nitrogen.

Hello. I never transplanted but I didn’t feed anything other than calmag during veg. I think it did use up the medium’s nutrients. I was trying out no nutes during veg since my first grow got nute burn. I’ve read many time ffof has enough nutrients to get you close to finish. I wanted to test that. This being my second grow, I was shocked to how quickly nutrients get used up during flower. I fell behind the curve a little. Thankfully, good advice helped out. I will use nutrients during veg in the future. Once I learn to grow confidently I plan on changing soil and nute brands. Did you look at the trichomes? Do you think it’s ready?

What’s up all? I’m on day 51 of my seedsman white widow auto. I’m growing in ff of. From seed until a week into flowering (roughly 30 days) I gave both but cal mag and ph’d ro water. So, absolutely no nutes up until about 2 weeks ago. I started feeding very lightly with tiger bloom and big bloom. I only used 5 ml and 10 ml respectively. I suspect a nitrogen deficiency based on what I see. The plant is still a ways out from being ready to chop based off trichomes and pistils. Do you agree this looks like nitrogen deficiency? I think by not feeding at all I may have used up the soils nutes and now lacking. Thanks in advance.

if you tried cal-mag and nitrogen, maybe you could give her a a little bit of Bio-Ag's TM7 or Cytoplus 1/8 to 1/4 tsp per gallon of water. If that doesn't help then you can rule out micro-nutrient deficiency and chalk it up to leaf senescence (leaf aging process)

Any indoor grow I've ever done has been in ffof. I love it. Here's my advice when using it, a solo cup has enough for like 2 weeks, a one gallon pot has enough for 1 month. After that you will have to feed. Your plant uses nitrogen during flower, might not uptake it as much but it still uses and needs it. When doing autos in ffof, you'll feed veg nutes once, then a half and half then full bloom. I try to go less when feeding as well so I get it. I usually feed once a week to once every 2 weeks depending how my waters go with photos. With autos you dont always get to feed how you want. Some have to do a half and half feed then straight bloom. I dont ever use ro water but if you do, you have to add micro and macro nutes or you'll get a def. Usually that way in every medium as well not just ffof if you use ro water. I did get to look at the trichs as well and you're about 4 weeks away maybe 3 at the earliest. I sont ever worry about trichs till 90+% of my hairs have already changed and I only see some white here and there then I know I have about 2 weeks left max.

Dang! 3 more weeks. I thought I was close to harvest in days. No wonder why my first grow wasn’t very potent. I am using ro water only because my water is very hard and has a high ppm count. I feed with grow big, big bloom and tiger bloom. Oh, and calmag.

Mcoocoo · Oct 3, 2019

the flowers don't look finished yet, they have a few weeks to go. They are filling out nicely. It could just be leaf the older leaves dying off. The older leaves act as nutrient reserves and the flowers will take what they need from them as they bulk up. Do you pH your nutrient solution before you water? It is also a good practice to check the pH of the runoff water that comes out after you water/feed them. It should be between 6.0 and 7.0

maybe 4 weeks to ripen correctly

I agree I stated 4 but 3 at the earliest lol. Usually when its 50 50 on the hairs that's around week 4 or 1 month in wo halfway there kenlv!

Yes that would probably be why the potency wasn't there, same with yield smell and taste

might have had some but would've been better! Always wait 5 days at least if you think it's ready. If it gets better wait 5 more. If it stops still wait. if 10 days go by and it's not doing anything else either you have a problem or it's done lol those nutes are ok but I could lead you to a better 2 part line with everything you need in it

Thank you. Yes I do pH my water. Usually 6.4. My runoff is below 6 but in soil I though runoff was difficult to determine. I tried on my last grow to raise runoff ph but I had to flush over and over before it changed. That didn’t seem right to me.

I’m going to keep feeding then for at least 2 more weeks then? Cool. I’m excited to see them grow. They are almost the same size as when I harvested my first grow. Thank you all.

ok since nobody guessed right
you have a mag deficiency 1 tsp per gal of epsom salt gets you there. Those leaves that are jacked wont come back so dont try to think about it.

No you dont need to use cal/mag every watering and probably shouldnt, if you use r/o dont remember if you do then maybe you should.. Cal/mag is a supplement.

For somebody to say that you use cal/mag one time at week four in soil is crazy and for you to say that is what your going to do next time is crazy, dont blindly do things that people put out on the internet. Do your research.

And checking ph run off is silly and not needed. At all. Microbes regulate the ph at the root surface I would get some microbe action going if you want to up your game. Your microbe game that is. Measuring ppm run off is just as silly and not needed if you feed it correctly but at least that will tell you where your at if you think that you have a hot pot.

Thank you for your post. I like your advice of doing my own research. Doing my research literally led me here. I understand that it is crazy to blindly follow advice. I do feel comfortable following advice that seems to fit within the majority of the consensus with weight being given to higher ranking members. You don’t think it was potassium or nitrogen?

How did you determine mag deficiency? They all look similar on the chart of leafs showing deficiency. Can you explain what you see that brought you to that diagnosis? Thank you again.

It doesnt look like its P in the pics but they do like their P. Its mag and they are crazy for the mag. 1tsp of epsom salt will get you about 250 ppm of mag per gal. Notice I didnt say add cal/mag. Mag makes the plant green nitrogen makes it grow.

And you dont want to feed it any nitrogen at this stage of the game at all, even though if you feed it nutes something will have nitrogen in it you dont want to feed it any if you dont have to. Im talking about specifically feeding it nitrogen.

they are mag whores
blotchy leaves
the red petiole is an indicator as well.

You need to up the mag as needed in late flower. Any time really but in late flower they are working hard to make bud, mag is the center molecule for photosynthesis.

Gotcha. I can add epsom salt at the same time I feed?
