my plants are having trouble! PICTURES

Here are pictures of my grow, 5 early misty plants from Nirvana. They were going along fine and then all of a sudden they have gone to shit. Some have the leafs flipping almost upside down and turning yellow from the outside in. One plant has the tips curling upwards. The funny thing is There is a known female that seems to be doing just fine... no special treatment. I have been using a 20-20-20 fertilizer. the temp is around 70-75 degrees. my light is a 150 watt HPS bulb. a 2 foot my 3 foot growing space. Where do I go from here. I am thinking about putting them outside and see what happens???

ok that look like ph possibly because ph problems can lock out more than 1 nutrient at a time giving you odd looking problems....i would do ph test and fix probly need some lime and also that ahs happened to me where the females hold out better in more acidic conditions and what turned out to be males were the shitty looking ones...but not always the case so dont think they are all males just my experience

I have a tool that measures moisture and PH.. cost me like 10 bucks.. is that something that can be used to determine accurate ph? the tool reads 7.5 ph. Would that high enough to give me these fucked up results? should i test the water as well before watering? also my female is the first picture... how is she looking?

yes it would ....try to keep the pH around 5.8 or 6 it needs to be more acidic...

I would seperate all of those girlies out of that one pot. I hate those rectangle pots it collects water on the bottom. Sooner or later you'll get a salt build up and you'll try to flush them but it's impossible to drain all the water out of the rectangle pot. Sorry for coming off like an ass, but I just had a really bad experience with that type of pot. good luck

i dont think you need keep it acidic i would research that in grow faq i always thoughtto keep it 6.8-7 you could drop it a bit and it may help also flush with water and give it a week watering see what happen.....watch out for pollen sacks when 1 my plants look that it hermied

where did you get the ph meter for 10 bucks??

What kind of soil is that? Is your fert. old? For whatever reason PH lockout or old nutes or some kind of mineral def. the nitrogen is not getting to the leafs. I don't think outside is going to do any good unless your grow has bad ventilation. You need to ph your water before watering. If your soil or nutes are old get new. Other than that don't know what to tell you. Good luck. One thing that may help is any of the products like Superthrive or florilicous plus may help over a couple of feedings. They contain a lot of minerals and vitamins most ferts. esp. miricle grow do not have. If you have a def. it will help to cure that.

Also looks like you have over nuted.

what the hell is over nuted?

Well i dont know where u get those numbers but 5.8 wont do any good for plants... it need to be like 6.8... If you dont have exp about that please do not miss lead folks.

Sometimes you need to make your soil more acidic to help a problem. Let's say you have a P deficiency, you would need to make the soil more acidic so that P will become available for the plant. Something at 5.5-6.5 is ideal.

Used too much nutes. The plant couldn't handle the dose so it's leaves look like they do. Not saying that happened, but looks like it may be part of the problem. You tried flushing your plant with an all around fertilizer or just PHed water?

spring water is what I flush with. the next watering I do I am going to put a little PH aquarium lowering solution in the water and see what happens.

ya and it seems as if his pH is too high so i suggested he bring it down.. im not misleading him

Ahh, yes I see that your PH is fairly high. Bring it down to 6.5 and flush with that. A few days after that you might want to flush again with a mild nute solution. What size containers are you in?

You PH is too high, which is resulting in a sulfur lockout/deficiency. Flush with reg water to reset PH to 6.9-ish and then feed with some PH'd to 6.0 1/2 strength nutes. Then u'll be golden.
