Hi, I am growing these 5 strains in coco under a T5 light in my closet. I planted them about 3 weeks ago at the same time and there's some problems. I have General Hydroponics Flora Series. I used it when I first planted them (bad idea), but they recovered. I used the nutes the other day since I'm in the 3rd week of the grow. The amount I used is a 1/4 at the most of the recommended dosage so I don't know if they got burned from just that little bit of nutes. I have been watering them whenever they need it, like every other day or so. I read you are supposed to use nutes for every feed but I don't wanna risk making them even worse so I've just been using water. The ph is probably a problem too, since I don't have a meter. Which one should I get?

Basically, I don't know if they are burnt, or have deficiencies, or both. I thought the 3 part Flora Series was supposed to be enough? I guess not. I've been told to get cal-mag. Is there anything else I should get? And for cal-mag, what should I get? I found some on Amazon. Is there a certain kind I should get for coco? Do I need other stuff besides the Flora Series and the cal-mag?

I've been looking all over the internet but I can't totally tell what the problems are, but I have those general ideas that I mentioned. If anyone can offer some insight on this or offer any other advice, that'd be great. Thanks!

It seems pretty comfortable. Not too hot and not too cold. The lights aren't even that hot since its a CFL.

Come on johnny we need more accuracy than that on temps. They are N def because your using 1/4 str nutes , they are ready for full str now. Weak str nutes don't work in coco as it has nothing to contribute in nutes.

Hahaha I can't find my thermometer but the temp in my house is in the mid 70s so I'd say the temp in my grow room (closet) is a little more so around 80
