Tap water isn't the best, IMO, but many people successfully grow using it.... I'm not a fan of it because of the extras that the municipal water companies put in it.... But like mentioned, some people have no problems with it.... If you can, get yourself a source of RO or distilled.... This way you can completely control the amount of ppms in your nutrient mix....

Along with the Bio Bloom, you should get yourself the Fish Mix and Alg A Mic for a complete and balanced NPK mix....and some Cal-Mag....and a micro nutrient that you think will work for you....(I prefer Liquid Karma).... When thinking about nutrients, you need to think balance....

pH test strips are not very reliable.... If your nute mix has any tint to it at all, your pH reading has already been altered before you even guess what the pH could be.... Digital pH meters are the most reliable.... Milwaukee makes an inexpensive one....and you will have to get the pH calibrating solution as well.... Then to adjust your pH up and down, you simply get yourself some pH up and pH down....very inexpensive and last a long frigging time....

Have you tried running just one of the 400w HID to see if temps permit 18/6??? Just wondering.... Once you are able to control the temps, your plants are going to thank you with those 2 - 400watters....

Other than what was just mentioned, everything looked ok....IMO.... I can't really say what is causing the cauliflower look but I can say that most of the pics that I saw looked like healthy young plants.... I strongly recommend changing your water source and getting a complete line of nutrients.... pH is very important as well....and while we're at it, might as well get yourself a ppm meter....don't want you to over fert your lil ones....

Hope this helps....If you have any more questions, ask away....

CanGroIt Reviewed by CanGroIt on . 4 Seedlings, which look really wierd, 2 different strains??? Hey guys, So I germinated 4 seeds and got 4 sprouted. They are 2 x Ortega Indica feminized and 2 x Alquimista Feminized. (These are normal strains not autoflowering ones as i'm currently growing fine). So these seedlings have 2 and 4 leaves, they look really weird they only way I can describe them is cauliflower looking.. they look out of shape and deformed, but in a really odd way, I've taken pictures which you can see below.. but they don't do it justice.. I am not sure whats wrong Rating: 5
