need 2nd opinion

I've been trying out DWC, but I haven't been extremely successful with at and I am currently (trying to) diagnosing a plant problem, but would like a second Opinion. I am currently feeding 30mL botanicare progro and 20mL their micros, liquid karma in a 4 gal bucket using the ratios found on the label. My plant looks like this.

I've kept the pH around 6, I try to keep it lower, but I also try not to change the pH too radically at one time. I'm thinking maybe either Mn or cal/mag deficiency, maybe caused by a bad pH. I got a little lax about the pH and found it around 6.5-7, so I figured maybe caused by pH lockout. More pics at request if necessary.

I don't have access to a ec or tds meter, but I see what you're saying

I dont think its your fault just a retarded/mutant plant. Where did you get the seed?

It's a blackjack seed from nirvana

I am growing two Nirvana (a White Widow and a Raspberry Cough) and have learned the hard way that they really do not like strong nutes in their early stages. Now they are in late veg in soil ... and their appetites have become more normal. cn

so would you say like half strength?

Can't say what "half strength" is. My young Nirvanas showed burn above approx. 400 ppm. Go by what your instruments tell you! Hydro growers cannot really do without a ppm/EC meter imo. cn

Yeah bro in my opnion its a little eairy to be hittinf youre girl with nutes...id chop ir down to a quarter strenth....until youre girl bounces back...plusr with our your meter youre kinda shooting in the dark......chop thenutes ....until youre sure youre girl is ready for it

bought a meter, what do you guys think ofhttp://www.saltysupply.com/Dual-Inline-TDS-Meter-p/FX1358.htm?utm_source=GAN&utm_medium=affiliate&clickid=0004b501ee172cb40ae06a8910451418&utm_campaign=k211893It got solid reviews on the web, so hopefully it'll be accurate
