help i think my young plants are getting sick
Posted 05 September 2006 - 04:31 PM
The plants that look ill have a pH of about 7-7.1 while the plants that appear to be healthy have an average pH of 6.9. I tested the soil of the dead sprout with a kit that tested not only the pH, but the nitrogen and phosphorus in the soil. The nitrogen content registered as very high, while the phosphorus content registered as medium to low. The ill-looking plants have exhibited yellow leaves, sometimes turned upwards, slightly weak stems, and one sprout has yellow curled leaves with white tips. Some of the healthier plants have shown signs that their leaf color is lightening, althought they don't appear ill.
I have two solutions at my reach, one solution of ammonium sulfate that has a nitrogen content of 21, and a 20-20-20 fertilizer. Is my pH too high, and causing the sprouts to not receive nutrients? Or is my phosphorus too low, but adding the ammonium sulfate solution or fertilizer could cause the plants to have too much nitrogen? Or is there something else I should do?

You have far, far, far too much concern about nutrients and chemicals
I wouldnt add anything yet, these are sprouts and your talking all kinds of chemicals already I fear this is your problem.

listen to whats been said - soil growers should not add ferts to new soil for atleast 2-3 weeks. Get your lights nice and close 2-3" atmost if your using cfl or fluoro and 2' if your using a HID light.
what about nutes likes fish emulsion and blood meal? I ask only because I gave mine some fish emulsion this time around during their first 5 days since sprouting and they didn't show any signs of overferting (that I know about, which is not much at all).

organic ferts or otherwise , sprouts need nothing, just the soil they are in, you were fortunate...

Organics or chemicals, NO FERTS FOR FIRST 3 WEEKS. Why is this difficult? The soil without any ferts and the cotyledon leaves should have enough food for about three weeks of baby life. The single most common error that noobees (including myself at the time) make is OVER caring for our plants.

1.Does this growing medium contain any nutrient within it or is it totaly nuetral?
2.Does it require any additive such as perlite and/or vermiculite for moisture and airation or is it ok used just on it's own?
3.If there is NO nutrient present in Coco mix should I feed plants 1 week old or when?or do the plants just support themselves for first week or 2?
4.Can anyone reccomend a good organic nutrient for BioBizz Coco mix, Grow & Bloom types?
Sorry for all the questions but am a bit confused when folks say don't feed for first 1-2 weeks, does that only apply if you're using a soil mix/medium that already has nutrients or is it that the plant simply has its own nutrients for early growth:confused:
Thanks in advance of any replys [Please]

do not use soil with fertilizer additives & do not feed sprouts ANYTHING
I dont use these products (BioBizz Coco mix) read the labels
I find all soil mixes are lacking in perilite
I only use organics (bat guano & Alaskan Fish Emulsion) so you will need other recomendations from others about chemicals

As ganja said, don't use soil with nutrients added in it either. I did a search on your soil. Is this the one on the top of the page? http://www.u-grow.co...ng_Mediums.html If so, it looks ok. Just make sure there is nothing on the bag listing numbers in NPK form. Also, the soil says the ph should be from 5-6. This is too low for weed grown in soil. It should be between 6.3-6.8. If I were you, I would invest in a soil ph tester or some ph test strips maybe both. Then check if the soil has an NPK number and if so, do NOT use it.

pay attention m8!!
you say the plants are a week old "THEY ARE SPROUTS LEAVE THEM ALONE"
I already posted you need nothing for your sprouts yet your still looking for more fert choices
and I did give you a couple options already in the organic ferts
trying not to sound like im picking on you, but start your own thread, you have highjacked this dudes problem thread, when we come back to see your responses we have to search around to see where you have stashed your posted questions & responses

Don't worry about it Sam. Start your own thread with all the details on your grow, get some pictures up on there and send me a link. I would be happy to help you out further as I am sure Ganja would as well.
