Things aren't looking good!!

I have so many unhealthy looking plants and I have no idea what to do. I think the nutrients I am using are probably no good for cannabis cultivation. I am using Dutch Nutrient Formula 2 part solution. I also think that maybe my issues are a result of improper PH within my water, but I do not own a meter so I can't test it to be sure. I am currently using a hand mix blend of peat moss, pearlite, and vermiculite. I water roughly 400-500mL every 3rd or 4th day. My temperature stays constant around 23'C and my humidity never goes above 35%. I use tap water that sits for a minimum of 24 hours before being applied to the plants. I mix the recommended dosage for established cuttings in soil which according to the package is 2.5mL/1L. From what I can gather the majority of the plants seem to be showing Nitrogen deficiencies. I could be wrong in my diagnosis though. I am thinking that perhaps my best plan of action is to flush out the plants and start over. I am afraid though that if I am to flush a plant that is already possibly deficient I may cause even more of an issue. All the of the tops of the plants look healthy it is only the bottom leaves that are showing signs of issues. Should I trim the leaves off or allow them to stay. Please anyone who has input I 'd like to know what you are thinking. I have read all I can find to read but to read is one thing. To know how to act upon everything you've read without any of the actual experience is a whole other game.

PLEASE HELP

Anyone have any thoughts?

yer sort ya pH out and give it some more water and things should be ok

Well, Things that it aren't: watering issue, pH doubtful. Not rootbound. Not temp issue....... I think it has something to do with the nutrients, what is the ratio per gal? (im in the states) They might be too strong..Has this been something rapid or was it progressing over some time?

looks lke over watering to me. you didnt say how often you water, but that is what it looks like.

I could see the sagging as well (which is a symptom of overwatering) but its not the water...I think the roots are getting nute lock. What are the NPK's on your nutes? you also need a pH meter or 9.99 strip kit

I have seen this slowly happen. I wouldn't call it a rapid change. I have been rather busy with school and underestimated the severity of the issue.

Go back and read the post again I clearly state that: "I water roughly 400-500mL every 3rd or 4th day."

The total NPK of the 2 part DNF formula is 3-2-3 I believe. 2-2-0 and 1-0-3 I believe is the makeup of the 2 parts.

ok how often are you giving nutes?

I have been applying nutrients with every feeding. I am wondering if maybe that is an issue as well. I figured that because I was using a very low concentration of nutrients it was ok to feed every watering. Perhaps this was not the correct approach. I am thinking I want to begin to feed it nutrients organically. I found that walmart has a decent selection of organic nutrients such as Bonemeal

Looks like a ph problem/lockout. Peat moss is pretty acidic. Even when mixed with perlite and vermiculite. I would be that your medium is just too high in PH. However, try to get your hands on a ph test kit for pools or aquariums. Put your water through at ph 6.5 and then measure the ph of your run off. If the ph is too high or too low it is probably being affected by your medium. You could transplant into a more neutral soil mix. Ive had less problems with ph since growing in 100% perlite. Hope you can nip it in the bud

K you can't give nutes that often....once..... maybe twice a week depending on how strong you make it....I go with half of what the bottle says (if its the first time with a new product) because most nutes aren't made for mj. I would recommend laying off any nutes for 6-7 days, just straight 6.3 - 6.5 ph room temp water allowing for some run-off to occur. keep us posted and GL.

hey man its really easy go get bigger pots and miracle grow three month continuious feed potting soil and a bigger light, dont use any nutes untill you flower

Thank you for all the input guys. Does anyone know of some natural ways to change pH that would involve things I could find around the house. Maybe a couple drops of lemon juice a little bit of vinegar, things kinda like that, or am I going to have to break out my old chemistry textbooks. Relearn how to do pH balanced equations and then work off that.
