Plant Moisture Stress - Symptoms and Solutions

DaveCoulier said:

Also regarding promix, people often amend it with compost or earth worm castings, and/or organic amendments like bone meal/blood meal/alfalfa meal, etc, etc. Compost/EWC will aid in the digestion of your Bio-Bizz products from the extra microbes. You may want to try that out when you up-pot later on.

I think this is a MUST with promix IF using organic foods. I have done too much testing with promix, and all test results lead to the biological activity in promix just is not enough to work proper with organic foods. (works great with chems though!) Now if you add compost and or EWC then its a great enviroment for the microbes.
I usually dont just pop in right in the middle of someone helping someone else , but i feel i need to toss my 2 cents in before you get too far with the promix.

I get that same message when I try to go to the message via the popup. Go to your "My Rollitup", and there should be a link to my message in the middle of your screen.

thanks for all the replies? i'm thinking i shouldn't have bothered wasting my time posting? sussed it out myself with no help from RIU. the problem i dont think was moisture stress and is not due to the way i am feeding them or the nutes themselves. The sealant used to hold the airstones on the bottom tanks for some reason had not completely set, the sealant had set solid on the outside but when i pulled the stones out there was a little bit in the middle that was not set and this must have been putting god knows what into the water burning the plant. i'm only posting for the sakes of anyone else having a problem like this in the future if at all likely. thank you Uncle Ben for your addition.

I dont know if uncle ben is stiill around in this thread, but I definitely need someones help...

I posted this in another thread,so its kind of a repost, but I think its appropriate to whats being discussed...

White Rhino under 1000 HPS, 2 weeks. Soil/clone.

Title has most of the details. I have a white rhino baby that is in my room right now, its about 12 inches tall. It has some discoloration on the newest growth. Like a reddish brown color. I was thinking maybe nutrient lockout from PH, or some kind of Phosphorous or Iron deficiency. I have begun feeding with a mild nutrient solution, it is my own recipe that I use that is pretty complete. Before yesterday, i was just using water because I start my babies in Fox Farm Ocean Forest soil, and it usually burns my plants if I feed right off the bat.

So, Im going to give it a couple days to see if feeding them clears it up, but, I am worried it may be something else like:

1)Maybe not enough fresh air in the room? With the exhaust fan on, it gets down to 68-70 degrees. I am trying to run co2 as well, so, Id like it to be a little warmer, but its cold in January!! If I turn off ALL the fans and exhaust, then I get it up to 74, but then there is no air exchange or movement.

2)Too much co2? I have it set really low on the tank, but because only 1 fan and my exhaust fan are on, maybe its not leaving the room as fast as usual?

3)too cold? it gets from 59-61 with lights off, to 68-71 with lights on. Only 1 light is on, because they are just babies. I have my inline fans off too, to warm up the room as much as possible.

So, like I said, I began feeding last night, so I hope that gets them back to what they usually look like, which is a luscious green and FAST growth, around an inch a day it seems. Can anyone help?

Ive enclosed a pic of the best shot I could get of the discoloration on the new growth. Oh, the stems have red stripes too.

One more thing. SOme of the leaves seem swollen, if that makes sense. Also, some of the edges of the bigger leaves are turned up right on the very edge. Im thinking this is just from water transpiration? Too much maybe?

How close are the lights?

I had a plant that developed similar brown/red at the newest growth and it was because I had the lights too close. Once the light was raised up, all was taken care of. Hopefully thats your problem as well.

Yeah, I have moved them back, it didnt look like a burn, more reddish than brown, and the leaf isnt damaged, just discolored. I figured since the room was so cool could set the lights closer. Right now Im about 12-18 inches away from the tallest plant, about 24 inches from the smallest plants.

I experienced the same exact thing. It will get worse if you leave the lights and plant as is.

Id keep the 1k 20 inches or more away to start with.

Maybe you can get a good distance in this thread:

So UB. do you use nitrogen at the end aswell? Do you flush and for how long? I learned how to grow weed from overgrow a while back and pissed off when they shut it down. I see that your in the growbible for credits. What did they use you for? jw.
Do you think its a good idea to take all the bigg leafs off when your doing a 6 day flush? Should i wait till the last three days? Have you ever had a strain that wasnt suited for you?

If the plant requires it, of course.

Do you flush and for how long?

Flushing is a myth. I believe in plant health, not in unsubstantiated gimmicks.

Leave the leaves alone. Strain? Dalat is one pain in the ass for indoors.

ARe you for real? you explain that you discovered a chemical sealant problem (if you used any waterproof sealant it wouldnt matter if it were everywhere in the tank) anyway you bash RIU because no one told you this? lol thanks for the heads up I will make sure to never use anything toxic in my res

I have no problem with PM's. I can't open up something called "new visitor messages", like I said.

Grow a healthy plant, keep RH and temps fairly low during flowering, harvest at the right time, buy a book on indoor gardening.

u say keep temps during flowering low and grow a healthy plant. whats RH and what brand of feedings (AN, Biobizz,etc) do u lean towards?

RH= Relative Humidity. When it is high it leads to bud rot & Powdery Mildew. Its thought that lower humidity increases Trichome production. Ive never really looked into that much though. Your priority should be to keep humidity in check to prevent major problems and if it does increase Trichome production thats an added benefit.

UB doesn't use products "designed" for MJ. Thats one thing he'll tell you to get out of you head. A plant is a plant. It'll grow just fine with 'regular' nutes.

P.S. UB, I think you should put what nutes you like in your Signature. Ive lost count of how many times that question has been asked.

Hi Dave, sup?

AMEN, when it comes to learnin in a forum a person needs to read and research to find the right answers as there are so many contradictions as well as different styles when it comes to growing

I love the post that start out "Couldn't read the whole thing but it looks really good, can you help me with x,y,z"

and everyday I am simply entertained by reading new post & questions where so many wrong answers are given and when you interject with the right answer or the truth folks ignore it, cause it doesn't fit the parots version of things

Haha I've seen that many times. Pretty selfish imo. Tells me poster isn't gonna read my post and offer me a honest comment or advice. So then why should I offer them my comments or advice? I always thought speech was a give and take deal. So if you can't speak to me how am I supposed to hear you? haha

hey guys possibly another dumbass question here for you so please take it easy on me what does IOW stand? for i see ub uses it often but i haven't got a clue what it stands for thanks for the help guys
