help Brown Spots on Leaves Pics

35days in to flower ppm 700 ph.6 maybe N deficiency could you please advise

looks like a ph issue. soil or hydro? hydro needs to be around 5.5 and soil 6.8. 6 you will have nute lock outs which is waht it appears to be. what nute locked out would depend if soil or hydro. and at a month she should start getting nitrogen deficient which is normal. but there is more than that going on.
soil or hydro?

thanks mate in soil feeding with canna terra flores every 2 weeks up to 7 ppms just a basic garden soil john westland so if i took the ph up to 6-8 would this improve it and do you recomend raising the ppms thanks

sure, FYI- Mg and Ca get locked out of soil in ph 6.4 and under so def. raise up that ph to 6.8 or little higher first. I think your feeding for next time should be maybe 1x a week, and I would increase to that now. I would keep the ppms where they are. Just make sure you are using a bloom fert with little nitrogen and more potassium and phosphorous. does it have the N-P-K ration on your bottle?
She looks good, those spots would def. be from too low of ph but she looks quite well otherwise. You will not see improvement in those affected leaves but it should not spread to any other large fan leaves and do check constantly.

thanks very much for the time you toock to awnser
