No, I just checked and you are fine. I didn't know it needed to be lower for hydro... I'm seeing folks say 5.5 to 6.5...so you are good.

i would have to ask,(what kinda nutes are you using? seems maybe kinda like a lack of Potassium (K), (dont quote me,im sure theres more with more experince), and by the looks of that plants left leave.its kinda shaped like a v..thats usually has something to do with the humidity..I few more details may help us answer your question.otherwise check black leaves out in the search form.im pretty sure theres a few..
hope it works out.let us know.

but the top leaves look ok right? trim off the blackin leaves.cut them in half or off.depending on how bad. the new growth is what your really looking for.
u can always add some bone meal,its simple and works.
and a tablespoon of salt/gallon of water..shake.pour in your sprayer when you mist your leaves..
Candana Dry in your humidifier works well for C02
peace.

Nitrate - Ammonium is found in both inorganic and organic forms in the plant, and combines with carbon, hydrogen, oxygen and sometimes sulfur to form amino acids, amino enzymes, nucleic acids, chlorophyll, alkaloids, and purine bases. Nitrogen rates high as molecular weight proteins in plant tissue.
Plants need lots of N during vegging, but it's easy to overdo it. Added too much? Flush the soil with plain water. Soluble nitrogen (especially nitrate) is the form that's the most quickly available to the roots, while insoluble N (like urea) first needs to be broken down by microbes in the soil before the roots can absorb it. Avoid excessive ammonium nitrogen, which can interfere with other nutrients.
Too much N delays flowering. Plants should be allowed to become N-deficient late in flowering for best flavor.
Nitrogen Deficiencies
Plants will exhibit lack of vigor, slow growth and will be weak and stunted. Quality and yield will be significantly reduced. Older leaves become yellow (chlorotic) from lack of chlorophyll. Deficient plants will exhibit uniform light green to yellow on older leaves, these leaves may die and drop. Leaf margins will not curled up noticeably. Chlorosis will eventually spread throughout the plant. Stems, petioles and lower leaf surfaces may turn purple.

At six weeks of veg, plants should be a lot more developed than that. Your root structure is also pretty anemic. Getting enough oxygen in the nutrient solution? If so, it is something with pH or PPM.
