So I finally sucessfully got a start and have had great growth over the past couple weeks. All of a sudden this week my leaves began yellowing and having spots on them also some of the first true leaves have become crispy I have them on a 20/4 light cycle under a 150w hps. Any ideas on what is wrong with my plants?

soil? nutes? watering? feeding schedule?
cmon.
I could give you a pretty accurate diagnosis if I knew these things.
Its definitely nutrient-related. thats for sure.

Yes I did provide drainage for the cups. I have a mini 6" fan above the light blowing down on top of the light.I very rarely close the door to the closet as its in an extra room.

When you transplant them into a bigger pot, ditch the MG and pick up some Fox Farm Ocean Forest. You plants will take off when you do that.

They've been growing extremely well no issues with that just the discoloration of the leaves and the spotting. Plus what are other suggested soils that fox farm stuff is not sold any where locally.

thats not very good advice IMO. If hes a noob having trouble with nutes in soil and watering schedules than FFOF is going to be hell for him to work with. Ive seen experienced growers fry their shit with that shit. I use MG organic and my plants dont do that. I also researched and added my own components to it.

to the OP
that soil needs some perlite(Fox farm perlite is great)
looks like the constant watering is constantly feeding your plants the slow release nitrogen nutes and burning em. (for the record I didnt sprout mine in MG organic, I transplanted into it at 5 weeks old.)
let that soil dry some and try getting a moisture meter from lowes for 5 bux, they also sell ph soil meters also for 5 bux.
mixing one cap of peroxide to 1 gallon of water and feeding your plants helps with overwatering problems and also helps build strong roots.
you can transplant out of those cups now too.

the mg organic does not have slow release nitrogen, and i wouldnt be recommending 5 dollar tools that easily are thrown off or are just garbage in general(a ph meter should never cost lest the 50 bucks IMO)

to the OP, water alot less often. dryer soil encourages root growth which encourages faster plant growth. if your using distilled or RO water you will need to add epsom salts like the previous poster stated as the plant matures. i would cut back on the watering, water every other day at least, and see how they do

overwatering without proper drainage could be your issue. when putting the holes in the bottom of the cup, did you leave a small layer of pebbles or rocks to support drainage? if you have water'd everyday and alot of stagnent moisture is just chilling in the bottom of your cups, thats not good. roots need air and lots of it!

Ok kewl yeh I didnt start them in the MG Organic I started in MG Seed Starting mix then moved from jiffy greenhouse to red cups with MG Organic I have one more move to go. I grow out side year round near me so I am technically a noob when it comes to indoor growing. As for the drainage no rocks but I did cut large holes and slits up the sides of the red cups

Ive checked the reliability of the cheapo meter because I have a good ph meter. 5 buck meter reads the same as my 68 dollar one

I've done a lot of research on soils and have only heard of a few people burning plants on straight ffof, and most of the time it was something else that fried them. MG isn't the best for cannabis, and with a little research you will discover the same thing.

Just trying to help here. I have pretty much the same setup using the same soil except mine are outdoors. I started mine before researching and had the same issues you have. I recently switched them all over to ffof and they exploded with growth. Fox Farm even lists their soil as safe for seedlings.

all soils are different. If you know how to work it. Im not dissing FF or you. just saying if he cant control the soil hes using, Moving to FF would possibly set him up for failure.
