Is this a PH problem? wk4bloom

this looks like a number of things so im asking for help..2 different plants 4 weeks into flowering ..over the last 30 or so hours had some leaves changing

i premix my nutes in gal jugs....(2 5 gallon tubs in hydro)..always the same dose everytime so no goofs with that..(1 tsp dyno gro bloom per gal)
also been usen 1 tbs of mollasses every other jug, and add about a gallon between the 2plants each day.

iv never had a problem in flowering til this..and everything i look up looks like this


i use the ph lq tester..dont have the digital ones..so its hard to test ph with molasses in it..but its always 5.6 to 6.0 when mixed in jugs..thx for any help

It looks like broad-spectrum underfeeding to me. I see K, P, Ca/Mg, N deficiencies. On the Dyna Gro schedule, you should be at 2 1/2 times the concentration plus cal-mag. Why molasses? Are you in hydro? cn

ya hydro(DWC)not a circulating kind..always followed instructions with the dyno grow..nowhere does it say double the amount ..and i heard molasses is good..for taste bloom size.ect..can u get cal mag at a local store? walmart lowes ect

i found elsewhere ppl are saying to mix a little dyna-gro veg with the bloom to get the leaves green again..ill try that tomoro if raisen the ph didnt help..they are about to sleep now..
