Babies are sick, need help !!

[pokherking]

If some one can help please !!! So i have them under flourescent tubes about 2-3 inches away, water when they get dried out(every couple days) and just yesterday gave them some 20-20-20 plant food with their water, they looked like this before i gave them food though,bottom leaves are dying off and it appears to be spreading up the plants.Any suggestions would be much appreciated, thanx !!

When did they start looking like this? Did you give them fert to try and fix the problem? Cause that looks more like some type of burning from within rather than a nute defficiency. That was your first time feeding it? Even if it was that's still too young for food, I'm not an expert though.

20-20-20 is very strong for such young plants.
Water them to the point where the water runs out the bottom with plain tap water.
Test the pH of the runoff.
Check that it is between 6.5 and 6.9.
They are a LITTLE small to be feeding yet, and the first feeding should be with a much weaker fertilizer that is a real grow fert, such as a 6-2-2 mixed to half the recommended strength.

They started looking like this about 5 days ago, no i didn't start giving them food to fix the problem, i just thought they were ready for feeding.And yes that was the first feeding.I don't beleive that they are close enough to the light to get burned but maybe,well no i guess not because one of the babies that is doing this,wasn't as close to the light.

Well that explains why they looks so crispy, it's been deterriorating for a while now. It's not the light I can tell you that. If it were, those leaves would problably be brown by now. Plus you would have more damage on the top of the plant assuming you have most of the light overhead. I suggest you take stinkyattic's advice.

Don't know what your soil is but I imagine it has ferts already in it? Those things are nuteburned for sure.....which may be due to abnormal ph in the soil or....ferts already IN the soil.....plus you just added MORE ferts.

Are the plants still with you? If so....as the Stinky says....flush like hell.

They are in miracle grow potting soil,so yes i will flush them out, any idea on how much water to run through them ?? And i think i have another problem......i just tested the ph level of the tap water i was giving them from the start and the ph is about 7.4 and that is bad right ?? i am thinking of going and getting bought water from the store for them and check that ph level. Or is there a way to lower or raise the ph level in the tap water prior to giving it to the plants ? And when can i tell if they are males or females ?? Thank alot guys !!

Mg prefertilized soil is a big NO NO in growing. It is a proven fact that that soil kills small cannabis plants. Just to mch nutes in it for small plants like that you want to get organic, transplant, and give it plain water for a week. Then feed regularly.

[Weedhound]

I like bud expresses idea...a transplant would sove all your problems if you use quality soil (fox farms oceans forest I has been recommended to me) but if you can't transplant then I would flush those plants heavily with ph correct water (6.2-6.8) 3 -5 x the size of the pot (1 gallon pot....3-5 gallons of water) By the end of your flushing the ph should be the same going in as going out.

Id like to recommend 1/4 strength nute mix at the end but not that 20-20-20 stuff at all so don't unless you have something along the line Stinky recommended.

Is your lighting on 12/12? If not no...you can't tell at this stage if they are male or female. Without that info or how old they are etc.....plus photos of the nodes who knows he or she.

You can use baking soda to raise ph in a pinch and distilled white vinegar to lower it.
DONT use ph adjusters for aquariums....fyi.

Good Luck.

What is "disstilled vinegar" ??? When i went to go buy it i couldn't find one that said that, they said " Pure white vinegar" Any help? And my lights are on 24/7,don't know if the light is sufficient???i will post pics.They are 2 daylight bulbs and 2 full spectrum sunshine bulbs, both 4 feet long.I bought 18L of water from the store and tested the ph and it was about 6.8 so i gave the ones that are already transplanted lots of water, and i need to get some good soil to transplant the others.
