Plant Moisture Stress - Symptoms and Solutions

Sheesh, just kidding! Unless you give me complete day to day activities, your issues could be based on a dozen things.

Recommend a book on indoor plant culture. Mel Frank's MJ Insiders Growers Guide is hard to beat.

Good luck......

Still here givin out great advice. You're like one of my fav people UB. I link people to your lectures and lessons all the time. U know, u have quite a following. Ever think of writing a book? You could ghost write it and still make a lot of moolah. It would make a nice addition to my collection also. High five u cannabis guru u

I agree there too Dannyboy, Uncleben certainly knows his sh!t, he seems to only have to glance at a plant to see its problems. Utmost respect. Peace

yes agreed !

think outside the label !!




soil

i aggree with that..

Has Any one got any advice for me, my plants are in early flowering about 2weeks maybe less. 2 are looking good the third not so good. After reading Uncle ben's wisdom its clearly caused by moisture stress and looks like its induced some deficiencies as well now, spreading rapidly.

Severe yellowing edges of leaves in middle of plant, lots of curled leaves (they have been around for a while mind), lower smaller leaves are turning speckled pale yellow, and most now have red stems...basically its pretty messed up.

flushed it the about 2 days ago and then next day lightly fed it some bloom nute's 2-4-5 Earth Juice sugar peak.
only got rough ph tester kit, so soil ph was between 6-7, closer to 7. I fed the nutes slightly acidic to try bring the ph closer to 6.

potted in bio bizz soil mix
under a whimpy 125watt Cfl flowering spectrum.
wardrobe grow, fan for circulation, i leave the door open.



sorry pics are poor, worth noting there were a lot more yellow leaves but a bunch fell off yesterday when i touched them.

Leaving it alone might be the best option but would like to hear other opinions, cheers folks!

Sounds like the typical response from using cannabis specific foods. What's the micros values in your foods? They look chlorotic to me.

haha its first time i've used it too.
it says nothing on the bottle about micro's, and couldn't even find a website with it on. is says derived from molasses, bat guano, calcium nitrate, potassium sulphate, marine bird guano, phosphoric acid, and kelp meal.

guess theres a fair chance this stuff is shitt, heard mixed reports.

have you said what you use in this forum somewhere?

Nothing wrong with Walmart foods.

ben any chance of some good help
what i have is 4 bag seed plants in roots organics
75-80 deg for temps,fans, 8 cfl for veg and 150 hps for flower
they are a month old and have repotted about ten days ago.
i use ph tap water that sits over night and water every other day. and have only added nutrians twice at like half dose.
what should i do
you think over water, nitrogen burn, or just young plants in soil thats a little hot to start..?? learn me the ways o mighty one
thanks

What foods and at what rate are you feeding them? I see some margin curling which suggest moisture stress.

Ben
I use pure pro grow right now but have only given half strength two times every 3rd watering.
I let the pots dry out to the best I can tell (nubbie) . Think some cal/mag is what's needed.
Ph the runoff today and was way low . How can I raise the soil ph if needed. Thanks Ben ...

I too have a question for the great Ben, how come when i get heat and moisture stress i also get very dark green leaves??

Peace

Don't ever let the pots dry out and no need to worry about the pH.

Don't know, as they're not related.

Hey Uncle Ben...what do you think? Can't figure out what's up with this plant. It's in the same bucket with 3 others and two show no signs of issues whatsoever. One is faintly showing the same problem but this one is the worse. Plants are about 18 days old and there is a little bit of leaf curl upward on this one. It's in DWC with what I believe to be plenty of air pumping with the water line about .5-1" below the net pots.

Conditions:
Temps: 73-76
Res Temps: 66-69
PPM: 210-240
PH: 6.5

Other than being extremely stunted regarding vigor, they look fine to me. Curious, why did you go with DWC rather than soil?

UB

That's a good question....it looked interesting and seemed like a good challenge. I am also basing the grow off of someone else so I'm basically setting up exactly the same. So why do you think they are stunted...I know they don't look sickly but I'm trying to catch things before they are real trouble! Anyway appreciate the response!

Also, I have 1 2ft 2 bulb t5 over it...is that enough light? I just don't know why they would be stunted?

They're stunted because something is out of wack. Could be a combo of a dozen things. Being popular and looking interesting is your pathway to failure when it comes to cannabis forums. Are you a regular gardener?

I've done outdoors with great results in ground and obviously soil plenty of times so these problems I'm encountering are new to me especially since I have never started seeds in rapid rooters in a DWC, it's also been a while since I've started from seeds also. Soil was probably the easiest thing I've ever done. I said nothing of being popular but DWC does interest me. I like trying new things and this was the logical next step. I'm sure something is out of whack I'm just having trouble pin pointing it.
