9 days old plants yellowing please HELP!

[astronomy420a]

ok my bad! your flooding three time's aday, did you start seedling's in a small chunk of coco? if you did, when flooded doe's the level reach that chunk of coco? a little feeding, just a few tablespoons of water fed from the top around the base of the seedling. if your flood level reach's the coco chunk, that you started your seedling's in, then disregard everything i suggjest. you stated that you could not see root's yet to detirmine weather they were brown or slimy... thats why i suggjest feeding a little from the top! because the roots are in the starter chunk.:smokebuds:just throwing idea's out there!

Well I started the seeds in little coco plugs like jiffy but from another company called rootit. Germinated them in one of those propagators also from rootit. as soon as i saw roots coming out from the bottom of the plugs I put them under gentle light cfl only. I read here in the forums autos don't appreciate transplanting, so I thought putting them in the big pots would be best. First I fed them canna bio rhizotonic 0.4 EC for a few days, 2 sessions / day one in the morning and one in the evening. Cpl of days later because i read in C.E.'s guide I must increase the Ec with 0.1 every day, he sais around days 7-10 I should be around 1.2 EC so I started to add canna coco A+B 0.1 EC every day, 3 sessions of 5-10 minutes / day until yesterday when i was at .9 EC and the yellowing started.

I don't know what you mean by flooding i use the drippers i have from the attami wilma sytem, the blue ones. Water never really flood using those, coco just gets wet but water doesn't build up. It flows back in the tank. What you suggest with driping clean water from the top I did and it seems to have worked, the yellowing definetly stoped and they are now twice as big as they were yesterday new sets of leaves emerge (green). Last night I also flushed the entire big pots with a light mixture of water and canna flush, (for those who are not familiar with it, they say is better than just flushing with water because it washes the salts and buildups and leaves there all the trace mineral and what is needed). So far it looks good probably too early for a complete recovery but there's definetely growing no stunning or anything like that, and the yellowing is atl east stopped. I don't see any new yellowing appear, nor disappear (yet).

glad to hear they are on the mend.:dance: ijust fed four baby dragon's at the age they are now, i spoonfeed them right on the peat pellet's i use to start my baby's. they now sit in four gallon pots, no transplant shock.

What are dragons? I keep seeing people here speak dragons.. what's that all about? Is it some killer strain?

Sometimes people over complicate things, like tying your shoes - it's really easy, it's really basic and pretty much second motion - but some people like to do these exquisite knots and mess shit up. Keep things simple man, you've clearly invested in a quality system and have quality nutes. There's absolutely no nutrients in hydroton or coco and your plants are on their third set of true leaves with GREAT structure, no twisting or mutating at all - what does this tell me? Your EC/PPM is irrelevant because there is NO shock or stunting going on. The little plants are ABSORBING everything and then some at this point. There's a HEALTHY plant trying to thrive but it has insufficient nutrients to do so. You're starving the plants trying to obtain this EC in the fashion you read to do it - but all strains are different. Give them 1/4 str veg nutes and stick to that until about 4-6 sets of leaves then start kicking it up. If there was a tell all guide to growing out these lovely plants, all of these forums wouldn't exist. The best growers tailor to the need of their plants, don't treat all plants the same!

Hmm I can't treat them differently with the hydro system that I have, they are all connected to the same tank with the same nozzles and nutrients and everything. Also by all methods of checking if they starv or have enough food I'm not sure they are starving. I read somewhere another way to check if there's enough nutrients, is to check the EC daily, and if it drops that means they eat more than they drink water and should be increased, and viceversa. So far rinsing them and stoping the feeding for 2 days has turned them around and they are clearly recovering. If what you say that I'm starving them were so the effect of what I did flush + feeding stop shouldn't have been the oposite and they would get worse?

I'm really unexperienced and I don't know much but on my first grow I did the method you suggest, mainly because I didn't have an EC meter, so I added 1/4 then later 1/2 etc... after about 30 days my plants started to show problems, quickly ordered an EC merter and turned out the solution was at about 2.8 EC. After fixing the solution to a 1.8-1.9 strength and a rinse, it all went back to normal. Why would it be so different now? Incidentaly the plant that was the most ill now, is from the same batch of seeds as my previous grow...

I don't wanna sound like the noob who argues and knows best but I can't find logic in what you say, if the problem was they was starving, then what I did (starving them even more for 2 days) should of made it worse not better don't you think?

On a seond thought the problem might have only been that the lights were too far, and lowering the lights fixed it, wich is another thing I did, and then feeding and nutrients have nothing to do with it.

Anyways, so far they seem to keep recovering, I had another issue this morning, we had a power outage of about 6 hours, but I don't think this is any concern with auto's.. or is it?

clear improvement... you are on the mend... :gthumb:

looks like you had a ph or low nutrient issue to me as well... ph usually causes yellowing due to lock out... but this can occur when there simply arent enough nutes... WG is right on the hydroton and coco... no nute value AT All in them... strcily medium...


see the link in my signature on ph... it will help all your growing drastically.

Waaah that's a lot of reading, but I'm a nerdish dude i love that kind of stuff. Yesterday I was reading your post on photosynthesis, and I was thinking why didn't I had you as a teacher in school... hehe I will read it no doubt thanks!

PH problem could be, the nutrient solution on the day the problem appeared was a bit high (around 6.3-6.4), Some guys dismissed it they said my plants are too young for lockout, now is back at 5.8 that should be fine iinnit? I just gave them one feeding seesion for about 10 minutes, will see how it goes, for now you think my .9 Ec is ok or should I increase it? My thought is leaving it as it is for a cpl of days and then start slowlyu increasing it again if all is good... What would you do?

yes... leave a few... then up to say 1.2 I'd guess... I'm not really a hydro guy anymore tho...

but you are exactly right on the ph issue... nitrogen is green growth and a good portion of veg nutes... but potassium and a few others are really key to stem and root growth early on...now look:
