Help! New grower with sick plants!

[Osirix]

Hey everyone! So I am a brand new grower who went a little gung-ho on Amazon now that we are allowed to grow 12 plants legally here. My question to you folks: Over the past 2 weeks I have started to see increased yellow blotching and dying of lower leaves (I even completely lost one of my smaller plants.) I've been doing my best to research online and my original guess was a pH problem. However, I just got a pH meter today and it is indicating a range of 6.3-7.0 which seems to be an acceptable range for most plants. My other theory is maybe I have been over-fertilizing (gung-ho new grower problems)? I'm hoping that you guys and gals, being the experts, will pick up on something I have not.

Thanks!! Let me know if you need better pictures or more information

Also just a note about the pictures - the splotches are more yellow in real life. The grow lights make them seem more white in the above images

Hi !

It's quiet hard to tell but it looks like the symptoms I once had because of linoleum toxicity. Do you have linoleum in your grow room ? Because it tends to generate toxic gases for the plant, really bad stuff.

Give us some more infos like what soil do you use, did you used ferts...

I grabbed some more pictures to help.

Its a completely indoor set up with one of the reflective tents, using LED lighting. I used foxfarm "grow big" as my liquid fertilizer (see attached pictures for more info). As for soil, i've used Fafard "ultra potting mix"

Also in this picture burst i pulled some of the plants out of the grow lights so you can get a better idea of the true color change.

Also no linoleum in the immediate area!

Looks like they were a little over fed but otherwise doing OK. Just give them plain water next feed then a less hot mix the next time you do feed.

Never heard of this. Have had many rooms with linoleum floors and never a problem.

are you growing with a black light? wtf?

no dats no black Light lol. I woodnt recomend feeding within the first week since the soil has food already. try jus feeding wit plain ph'd water.. what kind of water are u using? if bottled water make sure to put some calls mag in it. some low amounts since ro water doesn't contain it like tap water does.. also make sure the water is room remp. I had problems dis grow because of cold water

I also keep my lights 2 to 3 feet away from plants. only time I keep it farther is if it's 1000 wat since dose let off alot of heat. ur light doesn't seem to let off tons of heat huh
